Orthodontic Researchers Ask, Where's Your Retainer?

Have you been wearing your retainer? It's a question countless parents ask of their children post-braces. Now Case Western Reserve University School of Dental Medicine researchers are getting serious about the question.


"We found little written about the kinds of retainers prescribed and how compliant patients are in using them," said Case Western Reserve's Manish Valiathan, an assistant professor of orthodontics and a member of the American Board of Orthodontics. He notes that there is a dearth of information despite the devices being common in orthodontics practice.

Consequently Valiathan and fellow researchers embarked on three studies that examined how people are using retainers, which types are prescribed and what happens when patients don't follow up orthodontic work with a retainer.

After randomly sending 2,000 surveys to orthodontists throughout the country, researchers received responses from 658 practitioners regarding the kinds of retainers they prescribe. The majority (58.2 percent) prescribed removable retainers; about 40 percent opted for fixed lingual retainers that, once in place, are worn for life.

Post-braces, the majority of orthodontists said they required wearing removable retainers full-time for the first nine months and then part-time after that. They also encouraged part-time retainer use throughout life.

Valiathan said that without retainers specific prior conditions may return but that definitive research does not exist as to what conditions require ongoing retainer use. More evidence is needed, he said.

Another survey study of 1,200 patients from four practices focused on patient compliance two years after prescribing retainers. Patients self-reported and 36 percent responded to the researchers' questions regarding type of retainer used, age, gender, length of time since braces were removed, and hours per day and night retainer is worn.

The overall responses showed that 60 percent wore retainers more than 10 hours a day in the first three months and 69 percent wore them every night. By the time retainer users reached 19 to 24 months, 19 percent were not wearing retainers but 81 percent were even if it was only one night a week. About 4 percent never wore their retainer at all.

Research indicated that many patients were still using their original retainers two years later a sign that teeth had not moved, Valiathan said. Additionally, researchers found that age, gender and the type of retainer did not impact compliance.

The third study was a pilot research project. It examined the ramifications of no retainer use within the first four weeks after braces removal. Researchers measured patients' teeth before and after for spacing issues, overbites, under bites and tooth crowding.

Thirty patients had the wires removed from their braces but kept the appliances affixed to the teeth to monitor any changes without a retainer. Nearly half of the participants showed no movement, and many showed positive settling of the back teeth including the molars. Some did require additional orthodontic treatment at the end of the four weeks.

"Further studies with a larger study population will let us know if some patients can go without using retainers," Valiathan said.

He added that orthodontic researchers need to study what kinds of conditions require long-term retainer use.

Defendant Pleads Guilty In Tooth Whitening Case, UK

25 Mar 2011  


In the first case of its kind the UK's dental regulator, the General Dental Council (GDC), has successfully prosecuted a non-registrant for performing tooth whitening, which the GDC regards as the practice of dentistry.

On Wednesday at City of Westminster Magistrates Court in London 48 year old Paul William Hill of Warrington, Director of PW Healthcare Consulting Limited, pleaded guilty to 4 offences including practising dentistry while not registered as a dentist or dental care professional between 2 October 2010 and 11 March 2011. Under the Dentists Act 1984 it is an offence for non-registrants to practise or be prepared to practise dentistry.

Mr Hill has been ordered to pay a total of £6,265 in fines and costs and PW Healthcare Consulting Limited, which traded nationally as Style Smile Clinics, has been ordered to pay a total of £6,765. The amounts include costs of £5,500 for the GDC.

The GDC launched the case last year after it received hundreds of complaints from members of the public and dental professionals about tooth whitening treatment being provided by individuals who are not registered dental professionals.

The GDC, which regulates all dental professionals in the UK, began criminal proceedings under the Dentists Act 1984 on the grounds that tooth whitening may only lawfully be provided by those who are registered dental professionals.

Charges relating to two other people and one other company have been adjourned until 18 May.

Chief Executive and Registrar of the GDC, Evlynne Gilvarry said:

"This case has significant implications for the dental profession and for public protection. The General Dental Council will now consider its position carefully with regards to the hundreds of other complaints about the illegal practice of dentistry that it has received. We are concerned about the risk to the public posed by such potentially hazardous treatment being provided by people without the training and qualifications necessary for registration as a dental professional."

3M ESPE and Straumann collaborate to develop a streamlined digital workflow for restorative dentistry

•    Companies plan to connect 3MTM ESPETM LavaTM Chairside Oral Scanner C.O.S. to the Straumann® CARES® digital platform for restoration of Straumann implants.
•    Companies plan to offer new 3M ESPE CAD/CAM Restorative materials through Straumann CARES, improving the workflow from both companies.
•    Collaboration builds upon their effort to drive the adoption of Dental Wings Open Software (DWOSTM) into the leading open global standard software platform for dental applications.

Cologne, Germany, 22 March 2011: At Europe’s largest dental trade fair, the International Dental Show, today Straumann and 3M ESPE announced that they are collaborating to develop a streamlined digital implant workflow that connects the Lava Chairside Oral Scanner C.O.S., to the Straumann CARES digital platform for prosthetic restoration of Straumann implants.
The goal of the collaboration is to increase accuracy, simplicity and productivity of the implant restorative procedure by combining technology solutions from industry leaders.
This new development will enable dentists to use the Lava C.O.S. to transfer digital scan information of the patients’ oral geometry to dental labs with the Straumann CARES system. This option also increases the breadth of the Straumann CARES digital offering.
In this new workflow, labs will retain control over the custom digital design of both implant abutments and final crowns. As announced earlier today, the two companies have selected Dental Wings Open Software (DWOS) as the core software behind the new Lava Design 7 Software and CARES CADCAM systems. This move allows both companies to channel their resources into developing one common software platform. This not only offers immediate benefits to the dental labs, such as simplifying choices, or minimizing training and investment risk. It also allows the three companies to focus on delivering additional indications and enhanced workflow functionality of the software to support multiple growing industry needs.
3M ESPE will continue to offer clinicians attractive restorative material solutions - from monolithic all-ceramic and hand-layered porcelain to zirconia restorations to new technologies to enhance the design and production of CAD/CAM crowns. In addition, the companies are working on offering new 3M ESPE CAD/CAM restorative materials through Straumann CARES, improving the implant workflow from both companies.

Biodegradable tooth-binding micelles inhibit Streptococcus mutans biofilm growth

San Diego, Calif., USA – Today, during the 89th General Session & Exhibition of the International Association for Dental Research, held in conjunction with the 40th Annual Meeting of the American Association for Dental Research and the 35th Annual Meeting of the Canadian Association for Dental Research, lead researcher F. Cheni will hold an oral presentation on a research study titled "Biodegradable Tooth-binding Micelles Inhibit Streptococcus mutans (S. mutans) Biofilm Growth."
This research was performed under the objective to develop tooth-binding micelles(TBM) using peptide based biodegradable tooth-binding moieties that can effectively bind to the tooth surface to provide prolonged drug retention in the oral cavity, but can also safely detach from the tooth by gradual degradation of the peptide. Di-phosphoserine, tetra-phosphoserine and hexa-phosphoserine peptides were synthesized using a standard solid phase peptide synthesis method. These oligopeptides were conjugated to Pluronic P123 copolymer using a click reaction.
The tooth-binding micelle was prepared by self-assembly of the modified Pluronics with the antimicrobial agent triclosan. The binding kinetics of TBMs on hydroxyapatite (HA) particles was evaluated using a UV spectrophotometer. For in vitro biofilm prevention studies, HA discs were pretreated with different TBM formulations prior to inoculation with S. mutans UA159, and subsequent biofilm formation was assessed. Biofilm growth was measured by calculating the colony forming units (CFU) recovered per disc. Specific differences between the log-CFU/biofilm of each experimental group were analyzed using the Student t-test. A p-value of < 0.05 was considered as statistically significant.
The binding kinetics of TBMs on HA particles were found to be fast (< 1 min). Higher binding capacity was achieved using tetra- and hexa-phosphoserine as binding moieties. In biofilm prevention study, the TBM treated groups all showed significantly lower CFU (2 to 4-log reduction, p<0.05) per HA disc compared to the control groups.

Single dose oral mefenamic acid for acute postoperative pain in adults.

Cochrane Database Syst Rev. 2011 Mar 16;3:CD007553. 
Pain Research and Nuffield Department of Clinical Neurosciences (Nuffield Division of Anaesthetics), University of Oxford, Churchill Hospital, Oxford, Oxfordshire, UK, OX3 7LJ.

Abstract

BACKGROUND: Mefenamic acid is a non-steroidal anti-inflammatory drug (NSAID). It is most often used for treating pain of dysmenorrhoea in the short term (seven days or less), as well as mild to moderate pain including headache, dental pain, postoperative and postpartum pain. It is widely available in many countries worldwide.
OBJECTIVES: To assess the efficacy of single dose oral mefenamic acid in acute postoperative pain, and any associated adverse events.
SEARCH STRATEGY: We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to December 2010.
SELECTION CRITERIA: Single oral dose, randomised, double-blind, placebo-controlled trials of mefenamic acid for relief of established moderate to severe postoperative pain in adults.
DATA COLLECTION AND ANALYSIS: Studies were assessed for methodological quality and the data extracted by two review authors independently. Summed total pain relief (TOTPAR) or pain intensity difference (SPID) over 4 to 6 hours was used to calculate the number of participants achieving at least 50% pain relief. These derived results were used to calculate, with 95% confidence intervals, the relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over 4 to 6 hours. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals was collected.
MAIN RESULTS: Four studies with 842 participants met the inclusion criteria; 126 participants were treated with mefenamic acid 500 mg, 67 with mefenamic acid 250 mg, 197 with placebo, and 452 with lignocaine, aspirin, zomepirac or nimesulide. Participants had pain following third molar extraction, episiotomy and orthopaedic surgery. The NNT for at least 50% pain relief over 6 hours with a single dose of mefenamic acid 500 mg compared to placebo was 4.0 (2.7 to 7.1), and the NNT to prevent use of rescue medication over 6 hours was 6.5 (3.6 to 29). There were insufficient data to analyse other doses or active comparators, or numbers of participants experiencing any adverse events. No serious adverse events or adverse event withdrawals were reported in these studies.
AUTHORS' CONCLUSIONS: Oral mefenamic acid 500 mg was effective at treating moderate to severe acute postoperative pain, based on limited data. Efficacy of other doses, and safety and tolerability could not be assessed.

X-ray machine from 1896 compared to modern version

I came across this article and thought it was interesting to compare radiographs from a machine over 100 years old! MJ

Scientists have dusted off X-ray equipment dating from shortly after the discovery of the rays in 1895, in order to put it through its paces.
Researchers from the same Dutch town where the system was originally built used it to produce striking images that belie its simplicity and age.
The team said the images required a radiation dose to the subject some 1,500 times higher than a modern X-ray.
Details of the research were published reported in the journal Radiology.

CWRU researcher sends message to postmenopausal women: 'Increase yearly dental checkups'

Postmenopausal women have a new health message to hear. Two annual dental checkups aren't enough. Older women need more, according to research findings from the Case Western Reserve University School of Dental Medicine and the Cleveland Clinic.

That message comes from a comparison study of women on and off bone-strengthening bisphosphonate therapies for osteoporosis.
Leena Palomo, assistant professor of periodontics from the dental school, and Maria Clarinda Beunocamino-Francisco from the Center for Specialized Women's Health at the clinic, set out to study the long-term effects of bisphosphonate therapies on the jawbone, but came up with this new findings that impacts all women after undergoing menopause.
Twenty-eight postmenopausal women with normal bones were compared with 28 women on bisphosphonate therapies for at least two years or more. The participants (all between the ages of 51 and 80) received conebeam CT scans of their jaws and a complete periodontal check for dental plaque, bleeding, and loss of bone attachment and of the alveolar bone socket.
Both groups of women had followed the recommended American Dental Association oral health standards to brush twice daily, floss and have at least two dental checkups a year.
The findings for bone strength and other markers for osteoporosis were similar for both groups. But the researchers found both groups had increased dental plaque levels, which could endanger the jawbone of normal postmenopausal women and reverse any benefits gained in bone mass.
Dental plaque is the fuzzy bacterial material that covers the teeth when you wake up in the morning. The biofilm is a mixture of bacteria, bacterial waste and food particles stuck to the teeth and provide nourishment for more bacteria.
While women from both groups had similar bone health results and women on the long-term oral bone-strengthening therapies showed no signs of bone death, they had abnormal dental plaque.
Their findings were announced in the article, "Is long-term bisphosphonate therapy associated with benefits to the periodontium in postmenopausal women?" that was published in the February issue of Menopause.
Menopausal women at risk for osteoporosis also are at risk for periodontal disease, which affects bone that anchors teeth, says Palomo. A prior study by Palomo showed that short-term use of bisphosphonates had increased bone density in the jaw.
But over time, if the hard plaque is left on teeth, it triggers the processes for gum disease. Gum disease, also known as periodontitis, is an inflammatory reaction that produces the cytokines protein reaction. Cytokines act like water runoffs on the side of the hill and erodes the socket that anchors the tooth in place.
If that bone loss isn't stopped, Palomo said, a woman could potentially lose her teeth.
She added that those cytokines also set in motion the process that weakens bones in osteoporosis.
Palomo said women may need to see the dentist as many as four times a year to control dental plaque by deep periodontal cleanings.
"Women also have to realize that bone disease and gum disease are two separate diseases," Palomo said. The bisphosphonate therapy isn't enough to keep jawbones strong and healthy, she added, that means getting rid of the dental plaque.

Factors affecting wear of composite resin denture teeth—24-month results from a clinical study

DOI: 10.1007/s00784-011-0534-y

Abstract


The objectives of this study were to measure the occlusal wear of composite resin denture teeth in patients wearing a complete denture and to evaluate factors affecting wear. Fifty participants provided with complete dentures in at least one jaw were included. Gypsum casts were made from preliminary vinyl polysiloxane impressions 4 weeks after insertion, then after 6 (t 1), 12 (t 2), and 24 months (t 3). Three-hundred and three posterior denture teeth were evaluated after 24 months. Wear was measured indirectly, from the casts, by means of a three-dimensional laser scanner device. Sequential images of the occlusal surfaces were digitized and superimposed (occlusal matching). Statistical analysis was performed by the use of mixed regression models, with the patient being a random effect. Mean wear (median, interquartile range; micrometer) of the entire occlusal surface was 8 (19) at t 1, 18 (34) at t 2, and 40 (61) at t 3. Maximum vertical loss (median, interquartile range; micrometer) was 92 (112) at t 1, 146 (148) at t 2, and 226 (184) at t 3. The dental status of the opposing jaw and the nature of the opposing material significantly affected the wear of denture teeth at t 3. Gender, daily wearing time, jaw, and type of tooth had no significant effects on the extent of wear. Clinically relevant vertical loss of composite resin denture teeth occurs after 24 months. Considering the limitations of this study, wear of denture teeth was affected by dental status and opposing material. The results suggest that wear of composite resin denture teeth exceeds that of enamel.

CT imaging in bisphosphonate-associated mandibular osteonecrosis: case report, pathological correlates, and review of literature

DOI: 10.1007/s11282-011-0059-8

Abstract


Osteonecrosis of the jaw is a severe bone disease that occurs as a result of reduced local blood supply. Bisphosphonate-associated osteonecrosis of the jaw usually occurs following dental procedures. We report clinical and radiological findings in a case of mandibular osteonecrosis associated with the use of bisphosphonate; the mandibular osteonecrosis was undiagnosed prior to cross-sectional imaging with computed tomography. The radiological correlation to the underlying pathological process and a correlative assessment of history, clinical, and imaging findings enabled the diagnosis. A discussion of differential diagnoses is provided to alert the oral radiologist to the presence of this condition in cases with typical imaging findings. The literature on indications for advanced imaging is reviewed to simplify the selection of the appropriate imaging modality for mandibular osteonecrosis.

Kerr Launches SonicFill

I have tried SonicFill and it is easy to place bulk fille dposterior restorations.
MJ
Posterior Restorations in Less Than Three Minutes

ORANGE, CA – (Advance Release) April 1, 2011 - Kerr Corporation, a leading manufacturer of technology for dental procedures has announced the launch of SonicFill, a first-of-its-kind, time-saving composite system that enables clinicians to perform posterior restorations with an easy-to-use, single-step, bulk fill technology that requires no additional composite capping layer.  Dentists utilizing SonicFill can go from placement to polished in less than 3 minutes on cavities up to 5mm.

Kerr’s proprietary sonic activation within SonicFill’s delivery system dramatically lowers the viscosity of the composite during placement, providing superior adaptation. The SonicFill composite then immediately returns to a non-slumping, highly sculptable state that is easy to carve without being sticky.  Outstanding mechanical properties, including superior strength, low shrinkage and high depth of cure, allow it to be placed in bulk increments up to 5mm so that dentists can use it with confidence in posterior restorations.

"We finally have a practical, efficient technique for placing posterior composites in one single, esthetic, bulk fill increment,” said Ron Jackson, DDS of Middleburg, VA. “SonicFill is a game changer."

“It’s truly rewarding to be able to offer the SonicFill system to the dental community because it is such a decidedly different and unique composite system that can dramatically save clinicians time,” said James Lobsenz, Kerr’s Product Manager. “And not only is SonicFill a tremendous time-saver, it has also proven, in a variety of third party clinical studies, to meet or exceed performance criteria when compared with either bulk fill flowables or traditional composites placed in layers.  The initial feedback we’re receiving from the clinician community is extremely enthusiastic – we are excited to be making the system available and feel SonicFill will change the way composites are done and ultimately the way clinicians do dentistry”.

Kerr Corporation, a wholly owned subsidiary of Sybron Dental Specialties, Inc., is a manufacturer of premiere dental consumables. Advancing esthetic dentistry through education and sustainable solutions based on clinician input, Kerr has become synonymous with integrity for dental professionals worldwide.

In Future Dental Implant Success Could Be Assured By Bone-Creating Protein

Using a bone-creating protein to augment the maxillary sinus could improve dental implant success, according to Georgia Health Sciences University researchers.


Dental implants, screws that anchor permanent prosthetic teeth, won't work if the bone in which they are anchored is too thin. Bone-thinning is a common cause and consequence following tooth loss. The current favored solution is to supplement the area with bone grafts to stabilize the implant base. But that technique is problematic "primarily because it involves additional surgeries to harvest the bone," said Dr. Ulf M.E. Wikesjö, Interim Associate Dean for Research and Enterprise in the GHSU College of Dental Medicine.

In animal studies, he and his team at the GHSU Laboratory for Applied Periodontal & Craniofacial Regeneration found that implanting bone morphogenetic protein in the sinus more new bone will form within four weeks than using conventional bone grafting at the same site.

"We found that BMP induced superior bone quality over that following bone grafts, which improves the chances for successful implants," Wikesjö said. "BMP is phenomenal, because it's a true, off-the-shelf product with ease of use that can produce real results, and it could be the new gold standard for this procedure."

According to the American Association of Oral and Maxillofacial Surgeons, 69 percent of adults ages 35-44 have lost at least one tooth due to decay, disease or trauma, and 26 percent of adults have lost all permanent teeth by age 74. Before dental implants were available, the only options for replacing these missing teeth were dentures and dental bridges, both of which could lead to further bone loss. Implants provide patients with numerous benefits, including improved oral health, appearance, speech, convenience, durability and ability to eat.

National Smile Month To Bring Out The 'Smile Factor', UK

The UK's leading independent oral health charity, the British Dental Health Foundation, is delighted to announce the theme for this year's National Smile Month, the 'Smile Factor', running from 15 May - 15 June.


The aim of the campaign is to put the smile back on peoples' faces and help them display their full personalities through the 'Smile Factor' theme. Now into its 35th year, National Smile Month remains an integral part of the Foundation's work in promoting greater oral health. As in previous years, the Foundation will also be raising the awareness of a healthy diet and the link between good oral health and good overall body health and promoting the three key messages of brush for two minutes twice a day using a fluoride toothpaste, visit your dentist regularly, as often as they recommend and cut down on how often you have sugary foods and drinks.

Chief Executive of the British Dental Health Foundation, Dr Nigel Carter, described the thinking behind this year's campaign.

Dr Carter said: "A smile can be a very powerful show of emotion, yet not everyone has the confidence to do so. They say you can hide behind a smile if you are not happy or are self-conscious about your teeth, so many people are missing out on showing their very own 'Smile Factor'. Others are being held back by poor oral well-being and its impact on their general health. This year's campaign is designed to challenge those perceptions and get you smiling again."

Every year the Foundation encourages local communities, practices and individuals up and down the country to take part and get involved in National Smile Month, and as ever, there will be a wide range of different ways in which people can do just that. There will be many family and community events throughout the campaign - all of which need your support.

Computerized Tomography Scanning Offers New Uses In Oral Surgery Recovery

Computerized tomography (CT) has proved a useful tool in reconstructive dental implant surgery where a bone graft is required. It provides reliable information in diagnosis and treatment planning and has been used to determine the volume of bone for grafts. Now dentistry is finding postsurgical uses for CT as well.


An article in the current issue of the Journal of Oral Implantology relates two case studies in which CT played an essential role. Both cases used CT scanning before and up to one year after the patients' oral surgery. With this technology, oral surgeons were able to gauge the healing process following surgery that reconstructs the jaw and prepares it for future implants.

Bone grafts where the graft material is harvested within the patient's own jaw are commonly used in this type of reconstructive surgery. Areas where bone can be safely harvested can be determined with CT scanning before surgery.

Dentists are now turning this technology in a new direction, following the patient's recovery progress after surgery. In one of the cases, the technology was used not only to evaluate the success of the implant, but also to check the condition of the graft donor sites. In the other case, CT scans helped determine the patient's readiness to receive three implants six months after the initial surgery, evaluating new bone formation, condition of the sinus membrane, and radiographic change.

While radiolucency was still apparent in the area where the two halves of the jaw bone meet, at 5½ months following the surgery in one case and one year in the other, the size of the defect was notably reduced. Healing was uneventful for these two patients, as they showed a good acceptance of the procedure. Past the one-year point of this study, CT scanning could also be used to evaluate progress of remineralization and other long-term changes.

Full text of the article, "Computerized Tomographic Evaluation of Symphyseal Donor Sites Used in the Reconstruction of the Posterior Maxilla: A Case Report of 2 Patients," Journal of Oral Implantology, Vol. 37, No. 1, 2011, is available here.

KöR® Whitening Deep Bleaching™ Results Now Achieved in Half the Time with Lower Cost



Introducing KöR® Whitening’s New Dual Accelerated,
Tri-Barrel Hydremide® Peroxide Technology

Rancho Santa Margarita, CA (February 24, 2011)Evolve® Dental Technologies, Inc., an innovative research, development, and dental product sales company, recently announced its most recent research and development resulting in a reduction of in-office whitening time by 50% and significantly lower cost to dental offices, yet providing the same intense whitening results.  These new advances are made possible by the introduction of Evolve’s new Dual Accelerated, Tri-Barrel Hydremide® Peroxide technology.

“The KöR® Whitening Deep Bleaching System is the first teeth whitening system to utilize a tri-barrel design that keeps the whitening gel chemistry separated into three barrels,” explained Evolve Dental Technologies founder and chief whitening researcher, Dr. Rod Kurthy.  “The innovative new tri-barrel system has enabled the creation of our new Hydremide Peroxide formulation, resulting in the ability to achieve desirable chemical and physical properties of whitening gels never before accomplished.  The increased effectiveness has allowed Evolve to cut in-office whitening time in half by eliminating one of the two in-office whitening visits, thereby reducing the amount of whitening gel necessary and providing a reduction of cost.”

Evolve Dental Technologies is the first company to refrigerate a full line of whitening products from the instant of manufacture until received by dental offices.  This, in addition to the new Dual Accelerated, Tri-Barrel Hydremide Peroxide technology, is responsible for the ability to provide fully water-based gels with a neutral pH, yet still provide a long shelf life and assurance of receiving whitening gels at 100% potency.

Benefits resulting from constant refrigeration and the new Hydremide System include:
  • Whitening gels with an extremely low surface tension without running off the teeth.  The low surface tension results in greatly improved absorption of whitening factors into the microstructure of teeth.
  • The addition of a buffering system. All hydrogen peroxide-based gels generate acid as they release the whitening factors that whiten teeth.  This can result in an acidic level as low as pH3.  Acidity increases sensitivity and slows the whitening process.  Addition of a buffering system results in the maintenance of normal pH, greatly lowering sensitivity and maintaining rapid production of bleaching factors throughout the application time.
  • Two distinctly different chemical accelerators.  These increase the ability to force the generation of effective whitening ions and radicals instead of simply water and molecular oxygen.
  • The ability to provide fully aqueous and neutral pH gels.  This results in an osmolarity as low as 1/11th that of ordinary gels that may have an anhydrous base with acidifiers added (necessary to extend shelf life when refrigeration is not utilized).  The lower osmolarity results in much less osmotic force on dentinal tubular fluid, greatly decreasing sensitivity experienced during whitening procedures.
  • An 18-24 month shelf life, yet still providing extremely unstable whitening gels. Unstable gels release whitening factors rapidly and effectively when placed in the patient’s mouth.

Peroxidase antioxidant is found in both saliva and sulcular fluid, and will destroy peroxide gel on contact.  Critical to the KöR Whitening system is the unique fabrication of KöR-Seal Deep Bleaching Trays. The fabrication may be performed by dental office staff or by the KöR Laboratory.  KöR-Seal Trays provide a “seal” at the cervical 1 – 1.25mm of the teeth, effectively sealing whitening gel in the trays, and sealing damaging saliva and sulcular fluid out.

Salivary and sulcular fluid peroxidase is so destructive, it is capable of destroying peroxide within ordinary bleaching trays in minutes, resulting in only 25-35 minutes of active whitening.  The combination of slow-release KöR Whitening at-home gels and KöR-Seal Deep Bleaching Trays enables a full 6+ hours of whitening activity.

Evolve® offers whitening systems for every situation and type of patient, from average patients to geriatric patients and even tetracycline-stained patients.  KöR Whitening systems include:

  • Max – the most popular KöR Whitening system. This system is the most effective and predictable for all average patients.  Protocol is two weeks of at-home whitening with 16% carbamide peroxide and daily desensitizer application, followed by one in-office whitening visit with 34% Hydremide® Peroxide. Use of retractors and paint-on gingival barrier (provided in the kit) are utilized during the in-office whitening visit.
  • Standard – effective and predictable for dental practices that prefer not to use retraction or paint-on gingival barriers.  Protocol is two weeks of at-home whitening with 16% carbamide peroxide and daily desensitizer application, followed by one in-office whitening visit with 13% Hydremide Peroxide.  Neither retractors nor paint-on gingival barrier are necessary during in-office whitening.
  • Max Ultra – used only for rare difficult cases such as tetracycline stains, fluorosis, and geriatric patients.  Protocol is an in-office whitening visit with 13% Hydremide® Peroxide, followed by at-home whitening with 16% carbamide peroxide and daily desensitizer application, and then a second in-office whitening visit with 34% Hydremide® Peroxide.
  • KöR-Night – effective whitening for patients or practices that prefer at-home whitening with no in-office whitening.  Protocol is wearing KöR-Seal Trays with slow release 16% carbamide peroxide and daily desensitizer application for two weeks at night.
  • KöR-Day – effective whitening for patients or practices that prefer daytime at-home whitening with no in-office whitening.  Protocol is wearing KöR-Seal Trays for one or two 45-minute sessions per day with rapid, aggressive-release 9% hydrogen peroxide and daily desensitizer application.

Evolve Dental Technologies offers deeply discounted start-up kits that include everything a dental office needs to start the KöR system. Included in the kits are all training (manual and DVD), a patient-presentation photo album, all impression materials for multiple patients, in-office desensitizer, marketing kit, dental office listed on patient referral section of www.KORwhitening.com; as well as all whitening products, at-home maintenance kits, and free KöR-Lab-fabricated KöR-Seal Trays for two patients.

Evolve Dental Technologies is the first and only whitening company to provide a full satisfaction guarantee of their whitening systems.  When start-up kits are purchased, after two patients are treated following the details taught in the KöR Whitening Training Manual, if the dentist does not agree that the results achieved are the best ever seen, Evolve will refund the entire cost of the start-up kit.

BIOLASE Announces the Formation of a New Division: BIOLASE Imaging

BIOLASE to Offer a Full Range of Dental Imaging Products

IRVINE, CA--(Healthcare Sales & Marketing Network) - BIOLASE Technology, Inc. (NASDAQ:BLTI ), the World's leading dental laser manufacturer and distributor, today announced that it has formed a new division, BIOLASE Imaging, to design and distribute state-of-the-art extra-oral and intra-oral dental imaging devices. The creation of BIOLASE Imaging will enable the Company to offer high-quality diagnostic solutions to complement the minimally invasive dental treatment solutions offered by the BIOLASE Laser division.


BIOLASE Imaging has the potential to substantially impact equipment sales in the second half of this year, beyond the current guidance provided for 2011, and be a major factor in the Company's equipment revenues for 2012 and thereafter.

Chairman and CEO Federico Pignatelli said, "While BIOLASE continues to actively pursue various medical applications of its patented technologies, in dentistry we are now advancing from being a laser equipment provider to becoming a high-tech solutions-provider. For more than a decade, BIOLASE's laser technology has enabled thousands of dentists to provide clinically advanced treatments, with no pain or much less discomfort than with conventional dental drills and other instruments. With its Imaging and Laser divisions, BIOLASE is now the only company that can provide both high-precision intuitive diagnosis treatment planning solutions, fundamental to the delivery of quality dentistry, together with truly advanced laser treatment solutions thereby delivering the best biological and therapeutic results for dentists and patients."

The first series of BIOLASE Imaging products planned to be available include 3D Cone Beam Computed Tomography (CBCT), portable digital x-ray, and intra-oral camera devices. United States Food and Drug Administration (FDA) 510(k) clearance for these products is anticipated in the second quarter of 2011. The 3D CBCT device produces some of the most stable and highest quality images in the industry -- a critical feature in dental implant and oral surgery cases.

Digital imaging produces only 10 percent of the radiation of conventional film radiology, thereby reducing risks to the patient's safety.

Pignatelli added, "As planned, the product line will be manufactured under an OEM cooperative agreement with a leading European manufacturer and marketed worldwide under the BIOLASE Imaging brand. The systems offer cutting-edge imaging technology at competitive prices, while still providing a 50 percent plus gross margin to BIOLASE. We expect the product line to be comprised of several systems and range in price from $5,000 to $130,000. This is the next step in the evolution of the BIOLASE business model, as later in the year we plan to introduce more products and also start to integrate the imaging and laser technologies together in a complete solution that we plan to call 'Comfort Dentistry.' Our goal is to provide the most accurate diagnosis, minimally invasive and high precision treatment, and superior clinical outcomes with our truly biological surgical laser approach coupled with the latest and safest digital imaging instruments, including a non-contact 3D laser scanning system to allow for the ultimate mapping of a patient's mouth, with wide applications in restorative and cosmetic dentistry."

Pignatelli concluded, "Based on recent independent marketing studies, dental imaging and laser equipment are now at the top of the 'wish-list' of high-tech purchases of domestic dental practices, as there is a need to upgrade their equipment and tools for competitive reasons to cater to more demanding patients. The BIOLASE brand is synonymous with high-tech dentistry and biologically advanced equipment and is recognized by approximately 80 percent of dentists in North America, and in many other Countries around the World. In that respect, BIOLASE, in introducing its new imaging product line, is expected to not only leverage its extensive and highly regarded brand recognition, but also its valuable access to more than 10,000 dental practices that currently use its laser products."

BIOLASE markets through a direct sales force in the United States and Canada and a selected group of high end distributors, including Henry Schein, Inc. (NASDAQ:HSIC ) and Benco Dental, and internationally through a multitude of local distributors.

BDA Warns Oral Health Must Be Tackled By New Assembly, Wales

The government that is elected in May must act swiftly to build on improvements to the nation's oral health, the British Dental Association (BDA) will warn today. To ensure that patients in Wales receive appropriate care in a time of financial constraint, the new administration must tackle inconsistencies in Health Boards' approaches to dental care and address a lack of understanding about the appropriateness of Wales' dental workforce, the BDA is warning.

The BDA's manifesto for the May elections to the Welsh Assembly, Filling the gaps - further improving the oral health of Wales, sets out four priorities for the new Welsh Assembly Government: eradicating oral health inequalities; developing a new dental contract for Wales; supporting Health Boards; and planning for the future.

It argues that careful planning will be essential to meeting Wales's evolving oral health challenges, citing the retention of an increasing number of natural teeth by an ageing population as a trend that requires particular attention. It also calls for the expansion of Designed to Smile - a community-based programme of oral health promotion for children - and better planning of domiciliary dental care services. Concerns are also expressed that low morale could persuade significant numbers of more experienced dentists to retire, leaving patients in some parts of Wales struggling to access dental care.

Stuart Geddes, BDA Director for Wales, said: "Dentists have worked hard to bring about the improvement in oral health Wales has seen during the past thirty years. Dentistry here is now at a critical juncture, and the new administration will need to address a number of significant challenges. At a time when budgets will be under pressure, it must work with dentists to address Wales's persistent oral health inequalities and ensure it does not neglect vulnerable patients and those in rural areas."

New Insight On The Microbiota Of Severe Early Childhood Caries


01 Mar 2011 
Researchers at The Forsyth Institute have made a significant discovery about the nature of childhood dental disease. The scientific studies led by Anne Tanner, BDS, Ph.D., identified a new pathogen connected to severe early childhood caries (cavities). This bacterium, Scardovia wiggsiae, was present in the mouths of children with severe early childhood caries when other known pathogens such as Streptococcus mutans were not detected. This research may offer the potential to intervene and halt the progression of disease.

Early childhood caries, ECC, is the most common chronic infectious disease of childhood in the United States. Severe ECC can destroy primary teeth, cause painful abscesses and is the major reason for hospital visits for young children. This condition disproportionately affects disadvantaged socio-economic groups. This research, which will be published in the April issue of Journal of Clinical Microbiology, provides new insight on the microbiota of severe early childhood caries.

Dental caries is caused by an interaction between bacteria, host susceptibility and a carbohydrate diet that contains large amounts of sugar. Dr. Tanner published an updated evaluation of the diet associated with severe-ECC in collaboration with Dr. Carole Palmer at Tufts University in the Journal of Dental Research in 2010. The bacterial species Streptococcus mutans is widely recognized as the primary pathogen in early childhood caries. However, it is also present in people without disease and is not detected in all cases of childhood caries. This suggests that other species such as S. wiggsiae are also disease causing pathogens.

"In my work, I have seen the tremendous public health impact of severe early childhood caries," said. Dr. Anne Tanner, Senior Member of Staff, Department of Molecular Genetics, The Forsyth Institute.

"Understanding the causes of severe dental decay in young children is the first step in identifying an effective cure."

Sensable Dental Debuts Industry’s First Touch-Enabled Virtual Articulator

Intellifit™ Digital Restoration System Delivers More Productivity with New Capabilities 
The Industry’s #1 Selling TE CAD/CAM Solution for Partials and More Also Adds Veneers, Enhanced Crown & Bridge Functionality, More Fabrication Choices, Increased Printer Throughput 

WILMINGTON, Mass.--(BUSINESS WIRE)--Sensable Dental, a division of Sensable, announced the newest version of its Intellifit™ TE (Touch-Enabled) Digital Restoration System that offers dental labs even more choice, performance and flexibility in digitally designing and fabricating a wide range of dental restorations. The first and #1 selling system for partials and more, Intellifit – formerly named the Sensable Dental Lab System – now adds support for touch-enabled articulation, veneers, enhanced design features and fabrication choices for crown and bridge, as well as increased 3D printing capacity. 

“We've designed over 17,000 fixed and removable restorations over the past two and a half years using Intellifit, and the system's efficiency and value for us keeps on growing”
..Driven by the need to stay competitive and leverage a declining labor force of skilled technicians, dental labs are transitioning from painstaking hand waxing to streamlined digital design and production at a rapid pace. Sensable’s Intellifit is helping transform an industry from an era of manual hand-crafting to greater productivity, profitability, and precision. The system’s support for both fixed and removable restorations, produced faster and with heightened precision though its unique touch-enabled technology, allows dental labs of all sizes to gain a competitive advantage. Sensable is showcasing the newest version of Intellifit software starting today at three dental lab industry events in Chicago coinciding with the 145th Chicago Dental Society Midwinter Meeting. 

“We are using the Intellifit system to create both fixed and removable restorations, including all-ceramic monolithic crowns, bridges, and prepped veneers,” said Kristine Van Cleve, president of Dental Prosthetic Services in Cedar Rapids, Iowa. “We especially appreciate how the system makes pressing cost-effective by streamlining the process. We can quickly create customized digital tooth designs with full anatomy that perfectly match adjacent teeth, print, invest, and then press.” 

"We've designed over 17,000 fixed and removable restorations over the past two and a half years using Intellifit, and the system's efficiency and value for us keeps on growing," said John Aitchison, owner of Minot Dental Lab in Minot ND. "Partials, crowns, bridges, overstructures, substructures and veneers – we can do them all with Intellifit. The system gives us precise and consistent results and accuracy that far exceeds hand waxing." 

Highlights of What’s New in Intellifit: 

Touch-Enabled Virtual Articulation – ‘Feel’ the Fit 

•Intellifit's unique 3D 'Virtual Touch' interface and integrated touch-enabled articulator allow lab technicians to actually feel how the teeth – including the new restoration they are producing – will fit together in the patient's mouth. Articulators are essential to testing the occlusion of almost every type of dental restoration and lab technicians have long used them, as well as their sense of touch, to assess whether a restoration will allow the patient to function with the correct amount of contact and excursive movements. Intellifit's virtual articulator mimics the feel and function of a physical articulator, yet allows dynamic settings to meet patient specifications and freedom of movement in 3 dimensions. This industry first really emulates technicians' physical movements and sense of touch, enabling them to actually feel the fit. 
Prepped Veneers 

•Intellifit’s digital design tools, along with integrated digital tooth libraries from VITA® and Heraeus, streamline the process of creating highly-esthetic and perfectly-fitting veneers. 
•Intellifit eliminates tedious, time-consuming hand-waxing, ensures symmetry and provides consistency, regardless of which technician is doing the work. 
Enhanced Crown & Bridge Functionality 

•The addition of the Heraeus Premium® digital tooth library – renowned for its distinctively natural appearance and perfect fit – allows dental labs even more choice in creating aesthetically pleasing restorations for their doctors. With full anatomy “virtual” teeth, lab technicians can jump-start their designs for veneers, crowns, bridges, overstructures and substructures using Intellifit. 
•Intellifit’s streamlined margin detection delivers precise margin lines for even the most
challenging cases 
•Multi-die scanning provides accurate 3D scans in less than 20 seconds per unit 
•Touch-enabled, virtual articulator allows technicians to test occlusion of restoration – before it is produced. 
More Fabrication Choices 

•Pressing: Dental labs using Intellifit can design and fabricate full anatomy crowns, bridges and veneers and then press in popular all-ceramic materials from VITA and Ivoclar Vivadent such as Ivoclar Vivadent’s IPS e.max® and IPS Empress® Esthetic. Technicians of varying skill levels can deliver consistent, precise-fitting restorations in a fraction of the time of hand waxing, since Intellifit streamlines the number of steps required to produce high-quality pressed restorations. 
•Milling: Intellifit provides automatic tool compensation and output for industry standard milling machines. Labs can mill full contour overstructures and substructures in a variety of materials including zirconia and all-ceramic materials through Sensable’s network of authorized milling centers. 
Increased Printer Throughput 

•New up to 60% larger printing area, now available on the integrated, high-resolution 3D Systems Projet™ DP 3000 resin printer, delivers more throughput for increased productivity. Labs can print up to 200 parts in a single build. High-resolution resin parts can be used for casting, flasking and pressing and are ideal for fixed and removable restorations. 
“We’re proud to offer the industry’s first touch-enabled virtual articulator integrated into the Intellifit system,” said Bob Steingart, president of Sensable Dental. Allowing lab technicians to assess the fit of restorations by “feel,” in a way that they are used to – and giving them the tools to easily make adjustments – means more productivity for labs. Besides innovations like this, we’re committed to giving labs more choice, more flexibility and more restoration types from the same system. As the economy forces dental labs to more closely examine their productivity, Sensable offers labs practical solutions to better serve their doctors while achieving a strong return on investment.” 

The Intellifit Digital Restoration System is on display at Cal-Lab today at the Westin Michigan Avenue, booth 45; at Spectrum Clinical Day at the Wyndham Chicago on Friday February 25, booth 106; and at LAB DAY at the Sheraton Chicago Hotel & Towers, on Friday February 25 and Saturday February 26, in Sensable’s booth 200 and at its continuing education courses.
