Self-Report Questions May Help Predict Periodontitis

-->
Study confirms validity, reliability of self-report data in determining periodontal disease prevalence in US adult population

Chicago, IL – October 28, 2013 – The use of self-report questions may help predict the prevalence of periodontitis in US adults, according to the Centers for Disease Control and Prevention (CDC) and the American Academy of Periodontology (AAP). A clinical research report recently published in the Journal of Dental Research found that self-reported measures performed well in forecasting periodontitis in a representative sample of the US adult population.

The study utilized eight questions developed by the CDC and AAP that address gum health and treatment history, loose teeth, bone loss around teeth, teeth not “looking right”, and use of dental floss and mouthwash. Responses were obtained during the in-home interview component of the 2009-2010 National Health and Nutrition Examination Survey (NHANES). Response rates were very high, at greater than 95 percent, suggesting that adults responded well to the questions in the survey.

Researchers then compared the self-report data against clinically classified periodontitis assessed during the Full Mouth Periodontal Examination (FMPE) Protocol used in the 2009-2010 NHANES to gauge predictive performance. Statistical analysis indicated that the self-report data on gum health and treatment, bone loss and use of dental floss was found to be effective in predicting periodontitis prevalence.

“Over half of US adults have some form of periodontal disease, which makes periodontitis a significant public health issue. The ability to conduct valid and reliable periodontal disease research that demands fewer resources allows us to better understand community-specific disease trends and essentially provide better, more personalized treatment for patients,” explains Stuart J. Froum, DDS, President of the American Academy of Periodontology and Director of Clinical Research in the Department of Periodontics and Implant Dentistry at New York University Dental Center.

The American Academy of Periodontology supports the study’s findings that while clinical data remain the preferred measure for surveillance of periodontitis, self-reported measures offer an effective alternative for expanding population-based public health research of periodontitis in the US adult population. Due to good performance and cost-effectiveness, the self-reported models provide a viable alternative to clinical periodontal measures in population surveys where the latter may be impractical or cost-prohibitive. In the future, existing interview-based surveys at the local, state and national levels can serve as platforms for self-report-based surveillance of periodontitis.

Curve Dental Introduces Curve Connex: New Patient Portal and Appointment Reminder Capabilities



Curve Dental customers now able to provide their patients with convenient online payment capabilities while reducing no-show’s with automated appointment reminders
OREM, UT—Today Curve Dental, developers of web-based dental software, introduced a new package of patient communication features called Curve Connex, which includes a patient portal for online payments and an automated appointment reminder system that can help the practice reduce missed appointments.
The patient portal is an online extension of the practice wherein patients can make a payment, review current and past statements, view past payments, and see when the next appointment is scheduled for the family or individual. In addition, the portal provides the visiting patient with a library of more than 60 fully automated and professionally narrated patient education videos. Whenever a visiting patient watches a video the date, time, and video title is noted in the patient’s record. As a web-based application, Curve Dental is able to securely pass data to the patient portal in real time; synching with a local server is not required.
Curve Connex also includes a fully automated appointment reminder system. Patients can be reminded of upcoming appointments by e-mail or text message. With few limitations, Curve Dental customers determine how often they wish a customer to be reminded, when they are to be reminded, and how they are to be reminded.
“Curve Connex allows our customers to practice outside the walls of their office,” said Ian Zipursky, President and COO of Curve Dental. “Consumers use the web because it is much more convenient and flexible, which are hallmark benefits of managing the

practice on the cloud rather than with traditional software. More and more of us would rather pay our bills online and learn more about our account at a time and place that fits our lifestyle. We don’t want to be restricted by business hours and weekends. Additionally, our customers should experience a reduction in missed appointments with Curve Connex’s automated appointment reminder capabilities.”
As an accessory to Curve Dental’s practice management system, Curve Dental customers have the option to add Curve Connex to their monthly subscription at an additional charge. Curve Dental customers only need to call and ask to add the service to their current subscription.

Indirect restorations for severe tooth wear: Fracture risk and layer thickness

Available online 8 October 2013

Abstract

Objectives

This in vitro study investigated static failure risk related to restoration layer thickness for different indirect materials and compare them to direct composites.

Methods

Two ceramics (IPS e-max CAD, EmpressCAD (Ivoclar Vivadent)), two indirect composites (Estenia (Kuraray), Sinfony (3M)) and two direct composites (Clearfil AP-X (Kuraray), Tetric EvoCeram (Ivoclar Vivadent)) were chosen. Of each material, 25 discs varying in thickness (0.5–3.0 mm) were prepared and cemented to bovine dentine. For measuring compressive strength, samples were placed in a universal testing device. Each sample was uniaxially loaded until failure occurred. For each material a regression model based on the Weibull distribution was used to estimate the relation between restoration layer thickness and failure. Using these models, the chance of failure, standard error and 95% confidence interval for that chance is estimated. Groups of materials were compared as well.

Results

Except for Tetric Evoceram, all materials show a significant positive association between layer-thickness and compressive strength, with an increased strength of increased thickness. ProCAD performed significantly worse than all other materials, especially when compared to the other ceramic material (IPS e-max CAD) (p = 0.001).

Conclusion

For most tested materials, a thicker layer offers more strength, however, this property seems to be material/brand specific.

Clinical relevance

As direct composites showed the best results within the limitations of this in vitro study, dentists should consider these materials as a good choice for restoring severe tooth wear, and may offer superior performance compared to indirect composites and ceramics. For some brands of materials thicker layers result in a stronger restoration.

Factors associated with oral hygiene practices among adults with systemic sclerosis

Int J Dent Hygiene DOI: 10.1111/idh.12056 Yuen HK, Hant FN, Hatfield C, Summerlin LM, Smith EA, Silver RM. Factors associated with oral hygiene practices among adults with systemic sclerosis.

Abstract

Objective

To identify factors associated with oral hygiene practices in adults with systemic sclerosis (SSc).

Methods

In this cross-sectional study, 178 dentate adults with SSc received an oral examination which included measurement of oral aperture, assessment of manual dexterity to perform oral hygiene, as well as completion of the Center of Epidemiological Studies Depression (CES-D) Scale and an oral health-related questionnaire.

Results

Multivariable logistic regression modelling showed male, minority and high CES-D scores (i.e. clinically significant symptoms of depression) were associated with less likelihood of participants brushing teeth at least twice daily, but the presence of self-reported dry mouth symptoms increased the likelihood of toothbrushing. Having a dental visit in the past 12 months and use of an adapted flossing or interdental cleaning device were significantly associated with daily dental flossing; however, having difficulty flossing teeth reduced the likelihood of daily flossing.

Conclusions

Overall, demographic variables were strongly associated with toothbrushing frequency, whereas flossing self-efficacy and barriers were strongly associated with dental flossing frequency in adults with SSc. The results suggest that dental health professionals should take mental health into consideration when educating patients with SSc to improve their oral hygiene and consider making referrals for patients exhibiting suspected clinically significant depressive symptoms to mental health professionals for further evaluation and treatment. In addition, an appropriate adapted flossing or interdental cleaning device should be recommended to increase dental flossing practices in this patient population.

Effect of silica coating and silane surface treatment on the bond strength of soft denture liner to denture base material

Journal of Applied Oral Science
Print version ISSN 1678-7757
J. Appl. Oral Sci. vol.21 no.4 Bauru July/Aug. 2013
http://dx.doi.org/10.1590/1678-775720130066 

OBJECTIVE:
This study investigated the effects of different surface treatments on the tensile bond strength of an autopolymerizing silicone denture liner to a denture base material after thermocycling.
MATERIAL AND METHODS:
Fifty rectangular heat-polymerized acrylic resin (QC-20) specimens consisting of a set of 2 acrylic blocks were used in the tensile test. Specimens were divided into 5 test groups (n=10) according to the bonding surface treatment as follows: Group A, adhesive treatment (Ufi Gel P adhesive) (control); Group S, sandblasting using 50-µm Al2O3; Group SCSIL, silica coating using 30-µm Al2O3 modified by silica and silanized with silane agent (CoJet System); Group SCA, silica coating and adhesive application; Group SCSILA, silica coating, silane and adhesive treatment. The 2 PMMA blocks were placed into molds and the soft lining materials (Ufi Gel P) were packed into the space and polymerized. All specimens were thermocycled (5,000 cycles) before the tensile test. Bond strength data were analyzed using 1-way ANOVA and Duncan tests. Fracture surfaces were observed by scanning electron microscopy. X-ray photoelectron spectrometer (XPS) and Fourier Transform Infrared spectrometer (FTIR) analysis were used for the chemical analysis and a profilometer was used for the roughness of the sample surfaces.
RESULTS:
The highest bond strength test value was observed for Group A (1.35±0.13); the lowest value was for Group S (0.28±0.07) and Group SCSIL (0.34±0.03). Mixed and cohesive type failures were seen in Group A, SCA and SCSILA. Group S and SCSIL showed the least silicone integrations and the roughest surfaces.
CONCLUSION:
Sandblasting, silica coating and silane surface treatments of the denture base resin did not increase the bond strength of the silicone based soft liner. However, in this study, the chemical analysis and surface profilometer provided interesting insights about the bonding mechanism between the denture base resin and silicone soft liner.

Bond strength to root dentin and fluid filtration test of AH Plus/gutta-percha, EndoREZ and RealSeal systems

Journal of Applied Oral Science
Print version ISSN 1678-7757
J. Appl. Oral Sci. vol.21 no.4 Bauru July/Aug. 2013
http://dx.doi.org/10.1590/1678-775720130114 

OBJECTIVES:
To investigate the bond strength and seal ability produced by AH Plus/gutta-percha, EndoREZ and RealSeal systems to root canal dentin.
MATERIAL AND METHODS:
Sixty extracted single-root human teeth, instrumented manually to size 40, were divided into three groups (n=20) according to the sealer used; G1: AH Plus, G2: EndoREZ, and G3: RealSeal sealers. After filling using the lateral condensation technique, each sealer group was randomly divided into two subgroups according to the tests applied (n=10 for µPush-out test and n=10 for fluid filtration test). A fluid filtration method was used for quantitative evaluation of apical leakage. Four 1-mm-thick slices (cervical and medium level) were obtained from each root sample and a µPush-out test was performed. Failure modes were examined under microscopy at 40x, and a one-way ANOVA was applied to analyze the permeability. Non-parametrical statistics for related (Friedman's and Wilcoxon's rank tests) or unrelated samples (Kruskal-Wallis' and Mann-Whitney's tests) allowed for comparisons of µPush-out strength values among materials at the different levels. Statistical significance was accepted for p values <.05.
RESULTS:
There are no significant differences among fluid filtration of the three sealers. The sealer/core material does not significantly influence the µPush-out bond strength values (F=2.49; p=0.10), although statistically significant differences were detected with regard to root level (Chi2=23.93; p<0 .001="" ah="" and="" bond="" dentin="" higher="" in="" intraradicular="" medium="" obtained="" p="" plus="" realseal="" root="" slices.="" strength="" the="" to="">
CONCLUSIONS:
There are no significant differences between the permeability and global µPush-out bond strength to root canal dentin achieved by AH Plus/gutta-percha, EndoREZ and RealSeal systems.

Comparison of CaOH with MTA for direct pulp capping: a PBRN randomized clinical trial.

 2013 Jul;92(7 Suppl):16S-22S. doi: 10.1177/0022034513484336. Epub 2013 May 20.


Abstract
This practice-based, randomized clinical trial evaluated and compared the success of direct pulp capping in permanent teeth with MTA (mineral trioxide aggregate) or CaOH (calcium hydroxide). Thirty-five practices in Northwest PRECEDENT were randomized to perform direct pulp caps with either CaOH (16 practices) or MTA (19 practices). Three hundred seventy-six individuals received a direct pulp cap with CaOH (n = 181) or MTA (n = 195). They were followed for up to 2 yrs at regular recall appointments, or as dictated by tooth symptoms. The primary outcomes were the need for extraction or root canal therapy. Teeth were also evaluated for pulp vitality, and radiographs were taken at the dentist's discretion. The probability of failure at 24 mos was 31.5% for CaOH vs. 19.7% for MTA (permutation log-rank test, p = .046). This large randomized clinical trial provided confirmatory evidence for a superior performance with MTA as a direct pulp-capping agent as compared with CaOH when evaluated in a practice-based research network for up to 2 yrs.

Cellular signals between pancreatic cancer tumors and saliva support validity of salivary diagnostics

Pancreatic cancer is one of the deadliest forms of cancer. Most of those with the disease will die within the first year of diagnosis, and just 6 percent will survive five years.
The disease is typically diagnosed through an invasive and complicated biopsy. But a discovery by researchers at the UCLA School of Dentistry may be one major step toward creating a noninvasive tool that would enable clinicians and oncologists to detect pancreatic cancer through a simple risk assessment test using saliva.
In a study on a tumor-ridden mouse model, the UCLA researchers were able to definitively validate that pancreatic cancer biomarkers reside in saliva. The team was led by Dr. David Wong, the dentistry school's associate dean of research and the Felix and Mildred Yip Endowed Professor in Dentistry.
The findings are published in a recent issue of the peer-reviewed Journal of Biological Chemistry.
To date, salivary biomarker panels have been successfully developed for cancers of the breast, ovaries, lungs and pancreas. However, researchers in the field of salivary diagnostics are still attempting to understand how biomarkers produced by other parts of the body ultimately appear in the mouth. Scientists have surmised that RNA molecules - which translate genetic code from DNA to make protein - are secreted into extracellular spaces and act as an information signal system, representing an innovative model in intercellular signaling.
With this understanding, Wong's research team was able to demonstrate that tumor-derived extracellular RNA molecules are transported through organelles called exosome vesicles that originate at the source of the tumor and are re-processed into saliva as biomarkers. To prove it, the researchers examined mice models with pancreatic cancer whose saliva showed evidence of biomarkers for pancreatic cancer. When they inhibited the production of exosomes at the source of the tumor, the researchers found that the pancreatic cancer biomarkers no longer appeared in the mouse's saliva.
Their discovery supports their claim that tumor-derived exosomes provide a mechanism in the development of disease-specific biomarkers in saliva.
"This paper is significant because it provides credibility to the mechanism of systemic disease detection in saliva," said Wong. "We have been able to substantiate the biological connection between systemic disease and the oral cavity."
The team's findings come on the heels of a $5 million award that Dr. Wong recently received from the National Institutes for Health's Common Fund, a strong statement that saliva is proving to be scientifically credible for the detection of systemic disease and is advancing toward clinical maturation.
"Dr. Wong and his team have provided verifiable evidence to fully explore the use of salivary biomarkers for the detection of life threatening disease in a way that is noninvasive and doesn't cause pain for the patient," said Dr. No-Hee Park, dean of the School of Dentistry. "This new paper truly confirms a mechanistic tie between systemic diseases and their oral manifestations."

Biofilm removal by 6% sodium hypochlorite activated by different irrigation techniques

 

Abstract

Aim

To compare the removal of biofilm utilizing four irrigation techniques on a bovine root canal model.

Methodology

Fifty dentine specimens (2x2 mm) were infected with biofilm. The samples were then adapted to previously created cavities in the bovine model. The root canals were irrigated twice with 2 mL of 6% sodium hypochlorite for 2 minutes (4 minutes total). Following initial irrigation, the different treatment modalities were introduced for 60 s (3 x 20 s intervals). The evaluated techniques were needle irrigation, endoactivator, passive ultrasonic irrigation and laser activated irrigation (photon induced photoacoustic streaming). The controls were irrigated with distilled water and conventional needle irrigation. Subsequently, the dentine samples were separated from the model and analyzed using a scanning electron microscope (SEM). Fifteen operative fields were scanned per block and SEM pictures were captured. Two calibrated evaluators examined the images and collected data using a 4-degree scale. Non-parametric tests were used to evaluate for statistical significance among the groups.

Results

The group undergoing laser-activated irrigation using photon induced photoacoustic streaming exhibited the most favorable results in the removal of biofilm. Passive ultrasonic irrigation scores were significantly lower than both the endoactivator and needle irrigation scores. Sonic and needle irrigation were not significantly different. The least favourable results were found in the control group.

Conclusions

Laser activation of 6% sodium hypochlorite significantly improved the cleaning of biofilm infected dentine followed by passive ultrasonic irrigation.

Effect of fluoride varnish supplemented with sodium trimetaphosphate on enamel erosion and abrasion: An in situ/ex vivo study

Available online 3 October 2013

Abstract

Objective

To evaluate the effect of fluoride (F) varnishes supplemented or not with sodium trimetaphosphate (TMP) on enamel erosive wear followed or not by abrasion in situ. Methods: Ten volunteers were selected and randomly divided into four groups, according to the varnishes tested: placebo (no F or TMP), 5% NaF (positive control), 2.5% NaF and 2.5% NaF/5% TMP. Enamel blocks (n = 4) were mounted in palatal devices and received an application of each test varnish, following a double-blind, crossover protocol. After 6 hours, varnishes were completely removed and the blocks were subjected to erosive challenges by ex vivo immersion in citric acid (5 min, 4x/dia, 5 days). Following, half of the blocks were subjected to abrasion by brushing with a placebo dentifrice slurry for 15 seconds. Enamel wear (μm), surface hardness (SHf) and cross-sectional hardness (ΔKHN) were assessed after each experimental period. Results were analyzed by ANOVA, Student-Newman-Keuls's test and Pearson correlation coefficient (p < 0.05).

Results

The fluoride varnish supplemented with TMP promoted significantly lower wear and ΔKHN when compared to the other groups after erosive challenges, followed or not by abrasion (p < 0.05). As for (SHf) the fluoride varnish supplemented with TMP promoted similar results to the 5% NaF product, being significantly higher than the remaining groups after erosive and erosive + abrasive challenges (p < 0.05).

Conclusion

TMP significantly enhanced the effects of F on enamel wear after erosive challenges, followed or not by abrasion.

Pulpal response to sensibility tests after traumatic dental injuries in permanent teeth

Bastos, J. V., Goulart, E. M. A. and de Souza Côrtes, M. I. (2013), Pulpal response to sensibility tests after traumatic dental injuries in permanent teeth. Dental Traumatology. doi: 10.1111/edt.12074

Abstract

Background/Aim

The assessment of pulp vitality is one of the major challenges in dental traumatology due to the temporary loss of sensibility after trauma and because of the limitations of conventional pulp tests. The aim of this study was to evaluate pulpal response to sensibility tests and to determine their accuracy after crown fractures and luxation injuries.

Materials and methods

A total of 121 permanent anterior teeth from 78 patients treated at the Dental Trauma Clinic of the Federal University of Minas Gerais were evaluated. Responses to pulp sensibility tests were monitored for a minimum period of 24 months or until the diagnosis of pulp necrosis.

Results

At the first appointment, 68 teeth responded positively to sensibility tests, one tooth was necrotic and 52 teeth did not respond to sensibility tests but showed no other signs of necrosis. The initial lack of response was not associated with age (P = 0.18), but was related to the presence of luxation (P < 0.001). At the final appointment, 87 teeth were classified as vital and 31 were classified as non-vital. While a positive response shortly after trauma was a good predictor of vitality, a lack of response was not associated with subsequent necrosis. The final pulpal condition of the teeth that initially did not respond was associated with the type of injury, as displaced teeth tended to develop necrosis (P = 0.008). The accuracy of each sensibility test at the initial and final appointments was, respectively, 55.1% and 67.8% for the heat test, 55.9% and 77.9% for the cold test, and 57.6% and 89% for the electrical test. Conclusions.
A temporary loss of sensibility was a frequent finding during post-traumatic pulpal healing, especially after luxation injuries. All sensibility tests presented low accuracy shortly after trauma. The electrical test provided the best support for pulpal diagnosis after long-term follow up. The clinician must be aware of additional signs of crown discoloration and radiographic changes before initiating endodontic treatment.

Influence of chlorhexidine digluconate on the clinical performance of adhesive restorations: A 3-year follow-up

 

Abstract

Objectives

The aim of this clinical study was to evaluate the long-term clinical performance of non-carious Class V restorations with and without application of chlorhexidine digluconate to acid-etched dentine.

Methods

After the approval of the Ethics and Informed Consent Committee, 70 non-carious cervical lesions were selected and randomly assigned into two groups, according to the split mouth design. The control group was restored with a two-step etch-and-rinse adhesive (Adper Single Bond 2) following manufacturer's instructions; whereas in the experimental group 2% chlorhexidine digluconate solution was applied to acid etched dentine for 30 s after etching and prior to the adhesive application. All lesions were restored with a nanofilled composite resin (Filtek Supreme XT) and polymerized with a light-curing unit operating at 600 mW/cm2. Clinical performance was recorded after 1 week, 6, 12, and 36 months using modified Ryge/USPHS criteria in terms of retention, marginal discoloration, marginal integrity, post-operative sensitivity, and secondary caries incidence. Data were analyzed using Chi-Square, Fisher's exact test and McNemar tests (α = .05).

Results

After 36 months the control group showed a success rate of 88% in comparison to 76% of experimental group; however, no statistically difference between them was found (p = .463). Moreover, no statistical differences were observed between groups in the criteria post-operative sensitivity, marginal discoloration, marginal integrity, and secondary caries incidence between the two groups.

Conclusion

The addition of 2% chlorhexidine digluconate conditioning step does not improve the clinical durability of adhesive restorations.

Effect of three-year consumption of erythritol, xylitol and sorbitol candies on various plaque and salivary caries-related variables

Very interesting as the 3 sugars appear to act in synergy to reduce bacteria. MJ
 
Available online 3 October 2013

Abstract

Objective

The objective of the present paper is to report results from oral biologic studies carried out in connection with a caries study.

Methods

Samples of whole-mouth saliva and dental plaque were collected from initially 7- to 8-year-old subjects who participated in a 3-year school-based programme investigating the effect of the consumption of polyol-containing candies on caries rates. The subjects were randomized in three cohorts, consumed erythritol, xylitol, or sorbitol candies. The daily polyol consumption from the candies was approximately 7.5 g.

Results

A significant reduction in dental plaque weight from baseline (p < 0.05) occurred in the erythritol group during almost all intervention years while no changes were found in xylitol and sorbitol groups. Usage of polyol candies had no significant or consistent effect on the levels of plaque protein, glucose, glycerol, or calcium, determined yearly in connection with caries examinations. After three years, the plaque of erythritol-receiving subjects contained significantly (p < 0.05) lower levels of acetic acid and propionic acid than that of subjects receiving xylitol or sorbitol. Lactic acid levels partly followed the same pattern. The consumption of erythritol was generally associated with significantly (p < 0.05) lower counts of salivary and plaque mutans streptococci compared with the other groups. There was no change in salivary Lactobacillus levels.

Conclusion

Three-year consumption of erythritol-containing candies by initially 7- to 8-year old children was associated with reduced plaque growth, lower levels of plaque acetic acid and propionic acid, and reduced oral counts of mutans streptococci compared with the consumption of xylitol or sorbitol candies.

Roland’s New Compact Dental Mill

Roland DGA Expands its Award-Winning Line of Dental CAD/CAM Milling Machines with the New 4-Axis DWX-4

Roland’s New Compact Dental Mill Combines Precision, Affordability and Ease of Use into a Desktop Solution, Including CAM Software

Irvine, Calif., Oct. 2, 2013 – Roland DGA Corp. is expanding its DWX series of dental CAD/CAM milling machines with a new model, the DWX-4.  Affordably priced, the DWX-4 provides dental labs with precise milling capabilities, exceptional ease of use, bundled CAM software and a compact, desktop footprint.

“Like the award-winning DWX-50, the new DWX-4 compact dental mill is capable of milling a wide variety of materials with reliable precision,” said Brian Brooks, product manager for Roland DGA Corp.  “Its affordable price point and ease of use make the DWX-4 ideal for any lab just getting started in digital dentistry, or those labs with scanners who no longer wish to outsource production.  It is also the perfect addition to labs that need a second device for urgent jobs.  With the DWX-4, these labs can mill a single crown or bridge on demand without tying up their larger production mills.” 

Measuring just 13 inches by 14 inches and 16 inches high, the DWX-4 combines a small footprint with easy operation that allows even first-time users of a digital milling machine to achieve professional results. 

With the DWX-4, the workflow is simple.  After installing the material and milling tools in the machine, lab technicians use Roland’s intuitive Virtual Machine Panel (VPanel) to configure settings from a computer workstation.  An automatic calibration feature calibrates the mill at the touch of a button.  Then, VPanel automatically sends milling data to the DWX-4 to begin production. 

With a four-axis configuration that includes three axes (XYZ) and a rotary axis, the DWX-4 features an automatic tool changer (ATC) that changes milling tools as needed without interrupting the production process.  Prosthetic parts such as crowns and bridges can be produced using standard block and pin-type dental materials, including zirconia, PMMA and wax. 

An open-architecture system, the DWX-4 comes complete with its own CAM software and also works with commercially available CAD/CAM software for a seamless integration into an existing workflow.  Several features ensure flawless performance, including a status light that displays the progress of each job, and a tool-life management system that monitors tool usage and automatically notifies the user when a tool replacement is needed.  

An air blower prevents dust buildup, and a negative ion generator reduces static electricity when milling PMMA.  The DWX-4 also features an automatic diagnostic system that sends users an e-mail notification when an error occurs or when a job is completed.  Highly scalable, the DWX-4 offers multicast capabilities which allow users to connect up to four DWX-4s to a single computer.

Included CAM Software 

The DWX-4 comes bundled with an open-architecture CAM software package that accepts all STL file types. This easy-to-use  solution features a user-friendly interface and simple workflow for a short learning curve.  With the software, users can choose from a range of materials in various sizes. Automatic nesting and placement options help conserve materials. With pre-defined milling strategies, jobs can be sent directly from the software to the mill with no interruption during tool path calculation.  Customizable reports can also be generated once restoration cases have been completed.

Priced at $17,995, the DWX-4 is available from Roland authorized dealers.  For more information, including where to purchase, please visit www.rolanddga.com/dwx4 or call (800) 542-2307.

Flossolution® Debuts its Flossguard® Technology



Company launches two, all-new dental products designed to make flossing easy, fast and pain-free for all ages.

ORLANDO, Fla. – September 4, 2013 – Flossolution® today launches its first two products with Flossguard® Technology, the Flossolution 500 Series and Flossolution Lite.  Invented by Orlando-based dentist and Flossolution Founder Dr. Tim Pruett, Flossolution’s products are the first of their kind on the market, and tackle the challenges of everyday flossing by providing an easier, painless and more effective way to floss and brush teeth. 

"In our dental practice we’ve used every technique possible to motivate patients to floss, from showing photos of how much tooth structure is lost after removing decay between teeth, to adding up the chair-time and cost required to replace it,” said Dr. Pruett.  “For most patients, the resulting motivation is short-lived and the reasons for not flossing remain the same – it hurts, my gums bleed, it takes too long, the floss gets stuck, I don’t like putting my fingers in my mouth.  I finally realized that our patients understood the importance of regular flossing, it was just too difficult for most to make it part of their daily routine.  I knew we needed a new approach and that’s when Flossolution was born!”

Developed in Dr. Pruett’s lab and tested in his office, the Flossolution 500 Series and Flossolution Lite, are his solution to overcoming the common complaints shared by his patients on a daily basis.  The Flossolution 500 Series features a sonic powered handle to help make flossing quick and easy, while the Flossolution Lite is beneficial for those who need a smaller alternative or prefer a non-powered device.  Both products feature Flossguard and Bite Bumper™ technology. 

The Flossguard safely protects gums from flossing trauma by controlling the depth the floss can travel as it moves between tooth and gum.  The Bite Bumper acts as a soft pad for opposing teeth allowing for gentle biting pressure to be applied during flossing.  Flossolution products also feature tension-free flossers which increase functional effectiveness and safety while flossing.

In addition to their flossing capabilities, both the Flossolution 500 Series and Flossolution Lite feature Brush attachments to replace the Floss attachments, making it easy to go from flossing to brushing.  The Brusharms are designed to prevent what Dr. Pruett calls the second biggest problem in preventative dentistry today, toothbrush abrasion, by utilizing soft bristles and handles that promote gentle brushing techniques.
