Sesame Communications Releases Groundbreaking Research on Digital Marketing and Patient Engagement System Adoption and Use in the Dental Industry

National study reveals dental care provider perceptions of the top digital marketing and online patient engagement systems and their impact on practice growth and profitability
SEATTLE, WA — May 29, 2014 — Sesame Communications, the leading provider of cloud-based solutions to help dentists and orthodontists accelerate new patient acquisition and build patient loyalty, today announced the release of a national study that sheds new light on the key drivers of adoption and use of digital marketing and patient engagement technology and services by dental practices. This was a blinded study commissioned by Sesame and administered by Dental Products Report in April 2014.
This study surveyed 586 dental professionals across the nation—82% of whom were dentists. 92% of the population surveyed had primary or shared decision-making responsibility for digital marketing technology adoption. The study addressed all core areas of digital marketing and patient engagement including websites, SEO, social media, patient online review syndication and patient engagement platforms (sometime referred to as ‘patient login’ systems).
While core technologies such as automated appointment confirmation (one component of a complete patient engagement management platform) ranked highly (76.34%) as drivers of practice production, newer innovations such as patient accessibility to their records 24-7 from any mobile device (71.39%) and the importance of these systems to new patient acquisition (70.4% of respondents) also scored high marks from dental professionals. This same study also found that while the majority of practitioners had a practice website presence (78%), only 53% use SEO services, a key strategy to ensure their website is seen by prospective patients.
“As the vast majority of patients now rely on the Internet to choose and communicate with providers, the dental industry is responding and looking for the right digital marketing and communications technologies to increase efficiency and production.” said Diana P. Friedman, President and CEO of Sesame Communications. “This research confirms that the majority of practices see digital marketing and patient engagement platforms as a strategic component in their growth strategy. Those practices that have yet to embrace the Internet or have given it only cursory attention with antiquated technologies are at a distinct disadvantage compared to their competition.”
The complete results from this study are in the Sesame Communications Whitepaper The Digital Dental Practice, which will be available at on Monday, June 2nd 2014.

Masticatory efficiency in complete denture wearers with reduced dental arches – a randomised cross-over study

Iegami, C. M., Barbosa, W. F., Furuyama, R. J., Lima, J. R. B., de Campos, T. T., Minagi, S. and Tamaki, R. (2014), Masticatory efficiency in complete denture wearers with reduced dental arches – a randomised cross-over study. Journal of Oral Rehabilitation. doi: 10.1111/joor.12179


One obstacle to placing artificial posterior teeth in manufacturing complete dentures is a reduction of the space between the maxilla and the mandible. Occasionally, second molar placement is not performed, as it does not affect aesthetics, phonetics or comfort. The aim of this study was to compare the masticatory efficiency between patients wearing maxillary and mandibular complete dentures with reduced dental arches (without second molars) (WSM) and with full dental arches (FDA). Twenty subjects were divided into two groups and randomly received new complete dentures. Patients in Group 1 were given dentures WSM, and those in Group 2 were given dentures with FDA. After the post-placement visits, an initial masticatory efficiency test was performed with Optocal, an artificial test food. Fifteen days later, second molars were placed in Group 1 and removed from Group 2, and a new test was performed. Comminuted material was treated and sieved under vibration. The mean and standard deviation of masticatory efficiency with FDA were 10·4 and 8·1, respectively. In the tests WSM, the mean and standard deviation were 8·4 and 3·3, respectively. After removing the second molars in Group 2 and adding them in Group 1, the mean and standard deviation were 15·7 and 14·7 for Group 1 and 12·5 and 10·4 for Group 2, respectively. Within the limitations of this study, placing artificial teeth up to the first molars can be performed when needed without compromising masticatory efficiency.

Methods and preliminary findings of a cost-effectiveness study of glass-ionomer-based and composite resin sealant materials after 2 yr

Goldman AS, Chen X, Fan M, Frencken JE. Methods and preliminary findings of a cost-effectiveness study of glass-ionomer-based and composite resin sealant materials after 2 yr. Eur J Oral Sci 2014; 00: 000000. © 2014 Eur J Oral Sci
Cover image for Vol. 122 Issue 2

The cost-effectiveness of glass-carbomer, conventional high-viscosity glass-ionomer cement (HVGIC) [without or with heat (light-emitting diode (LED) thermocuring) application], and composite resin sealants were compared after 2 yr in function. Estimated net costs per sealant were obtained from data on personnel time (measured with activity sampling), transportation, materials, instruments and equipment, and restoration costs for replacing failed sealants from a community trial involving 7- to 9-yr-old Chinese children. Cost data were standardized to reflect the placement of 1,000 sealants per group. Outcomes were the differences in the number of dentine caries lesions that developed between groups. The average sealant application time ranged from 5.40 min (for composite resin) to 8.09 min (for LED thermocured HVGIC), and the average cost per sealant for 1,000 performed per group (simulation sample) ranged from $US3.73 (for composite resin) to $US7.50 (for glass-carbomer). The incremental cost-effectiveness of LED thermocured HVGIC to prevent one additional caries lesion per 1,000 sealants performed was $US1,106 compared with composite resin. Sensitivity analyses showed that differences in the cost of materials across groups had minimal impact on the overall cost. Cost and effectiveness data enhance policymakers’ ability to address issues of availability, access, and compliance associated with poor oral-health outcomes, particularly when large numbers of children are excluded from care, in economies where oral health services are still developing.

Longitudinal micromorphological 15-year results of posterior composite restorations using three-dimensional scanning electron microscopy

Available online 6 May 2014




Hybrid composite restorations in posterior teeth were evaluated over 15 years using the semiquantitative Clinical, Photographic and Micromorphologic (CPM) index. It was a further aim to quantitate the surface morphology by three-dimensional scanning electron microscopy (3D-SEM).


Thirty seven hybrid composite restorations (Ketac-Bond/Visio-Molar X, ESPE, Seefeld/Germany) were longitudinally followed up.
Parallel to clinical assessment replicas were taken at baseline, after 1, 5, 10 and 15 years and evaluated by SEM, and profilometrical analyses of 3D-SEM data were computed. The profilometrical results were statistically analysed by ANOVA. The level of significance was set to p < 0.05.


The semiquantitative micromorphological evaluation exhibited the most considerable deterioration within the first year and up to 5 years of function. Less change was detected during the next 10 years. The profilometrical quantification showed raising depth of the negative marginal ledges with a mean of 27.2 μm (range 0.6 μm to 94.5 μm) after 10 years, with no statistically significant changes from 5 to 10 and 10 to 15 years. The 3D-SEM revealed marginal grooves beneath the level of the ledges (mean 34.5 μm after 5 years) within the bonding zone, exposing enamel margins. Leakages, marginal fractures and surface roughness did not seriously deteriorate the quality of restorations.


Hybrid composite restorations of Class I and II cavities surviving the first five years performed well over 15 years of function. Quantitative 3D-SEM profilometrical measurements revealed the dynamics of marginal behaviour over time.

Brasseler USA® Introduces the ESX® Rotary File

Designed for Powerful yet Precise, Minimally Invasive
Endodontic Procedures

SAVANNAH, GA (May 15, 2014) – Brasseler USA®, a leading manufacturer of quality instrumentation, is pleased to introduce the ESX® Rotary File. Designed with several performance-enhancing patented features, ESX Rotary Files are designed for a powerful yet minimally invasive performance, maximizing the long-term success of the treated tooth.   

The ESX Rotary File is equipped with a patented ACP™ (alternating contact point) design that efficiently cleans 3 dimensionally as its sharp cutting edges engage with the canal walls at opposing intervals. The asymmetrical flute design alternates between zero to three points of engagement while moving debris coronally in a wave-like motion.  This mechanism allows the ESX to operate at a low torque setting yet at a higher speed, reducing stress on the file and root. In addition, the triangular cross section of the ESX Rotary File supports sharper cutting edges and a larger chip space for more effective debris removal. 

As with all Brasseler USA rotary files, the ESX Rotary File surface is treated with Brasseler’s exclusive proprietary electropolished finish. The electropolished treatment greatly improves resistance to cyclic and torsional fatigue often associated with the long-term use of dental rotary files.   

Another significant feature of the new ESX Rotary File is its patented booster tip. The BT Tip™ maximizes safety and efficiency and provides the user stress-free

apical progression and clearing of debris while respecting even the most challenging canal anatomy. The BT Tip features six cutting edges that smoothly transition to a true reamer design for increased cutting efficiency, and has an anti-ledging and anti-perfing centering mechanism that provides superior performance each and every time.

The adhesive strength and initial viscosity of denture adhesives.

Acta Odontol Scand. 2014 May 5. [Epub ahead of print]


Objective. To examine the initial viscosity and adhesive strength of modern denture adhesives in vitro. Materials and methods. Three cream-type denture adhesives (Poligrip S, Corect Cream, Liodent Cream; PGS, CRC, LDC) and three powder-type denture adhesives (Poligrip Powder, New Faston, Zanfton; PGP, FSN, ZFN) were used in this study. The initial viscosity was measured using a controlled-stress rheometer. The adhesive strength was measured according to ISO-10873 recommended procedures. All data were analyzed independently by one-way analysis of variance combined with a Student-Newman-Keuls multiple comparison test at a 5% level of significance.

Results. The initial viscosity of all the cream-type denture adhesives was lower than the powder-type adhesives. Before immersion in water, all the powder-type adhesives exhibited higher adhesive strength than the cream-type adhesives. However, the adhesive strength of cream-type denture adhesives increased significantly and exceeded the powder-type denture adhesives after immersion in water. For powder-type adhesives, the adhesive strength significantly decreased after immersion in water for 60 min, while the adhesive strength of the cream-type adhesives significantly decreased after immersion in water for 180 min.

Conclusion. Cream-type denture adhesives have lower initial viscosity and higher adhesive strength than powder type adhesives, which may offer better manipulation properties and greater efficacy during application.

Influence of light-curing mode on the cytotoxicity of resin-based surface sealants

BMC Oral Health 2014, 14:48  doi:10.1186/1472-6831-14-48
Published: 6 May 2014


Abstract (provisional)


Surface sealants have been successfully used in the prevention of erosive tooth wear. However, when multiple tooth surfaces should be sealed, the light-curing procedure is very time-consuming. Therefore, the aim of this study was to investigate whether reduced light-curing time (while maintaining similar energy density) has an influence on resin-based surface sealant cytotoxicity.


Bovine dentine discs were treated as follows: group 1: untreated, groups 2-5: Seal&Protect and groups 6-9: experimental sealer. Groups 2 and 6 were light-cured (VALO LED light-curing device) for 40 s (1000 mW/cm2), groups 3 and 7 for 10 s (1000 mW/cm2), groups 4 and 8 for 7 s (1400 mW/cm2) and groups 5 and 9 for 3 s (3200 mW/cm2). Later, materials were extracted in culture medium for 24 h, and released lactate dehydrogenase (LDH) activity as a measure of cytotoxicity was determined photometrically after cells (dental pulp cells and gingival fibroblasts) were exposed to the extracts for 24 h. Three independent experiments, for both sample preparation and cytotoxicity testing, were performed.


Overall, lowest cytotoxicity was observed for the unsealed control group. No significant influence of light-curing settings on the cytotoxicity was observed (p = 0.537 and 0.838 for pulp cells and gingival fibroblasts, respectively). No significant difference in the cytotoxicity of the two sealants was observed after light-curing with same light-curing settings (group 2 vs. 6, 3 vs. 7, 4 vs. 8 and 5 vs. 9: p > 0.05, respectively).


Shortening the light-curing time, while maintaining constant energy density, resulted in no higher cytotoxicity of the investigated sealants.

Going to the Dentist Linked with Overall Well-Being

OAK BROOK, Ill. (May 8, 2014) – Go to the dentist at least once a year and you are more likely to feel better about your life overall, according to Delta Dental Oral Health and Well-Being Survey1 results announced today.
In fact, Americans who go to the dentist at least once a year are 22 percent more likely to report their overall well-being – their physical and emotional health – as good or better compared with those who seldom visit the dentist.
“Going to the dentist regularly is one part of taking care of ourselves,” says Dr. Bill Kohn, DDS, Delta Dental Plans Association’s vice president of dental science and policy. “Taking care of ourselves is taking control, and we feel better about our lives when we do.”
Not surprisingly, people who visit the dentist more often also tended to report better oral health. Americans who visit the dentist at least once a year are 37 percent more likely to report their oral health as good or better versus those who infrequently find themselves in a dentist’s chair.
Delta Dental’s survey of 1,003 American adults found that income and education play an important role in getting to the dentist. For example, 86 percent of Americans making $100,000 a year or more visit the dentist at least once annually compared with 46 percent of Americans making less than $25,000. About eight of 10 college-educated adults (83 percent) had regular dental visits. For those Americans without a college degree, about six of 10 (59 percent) visit the dentist once a year.
The survey also showed some regional differences. For example, Americans in the Northeast (75 percent) visit the dentist more often than those in the South (60 percent), though that doesn’t translate to statistically significant differences in reported oral health.
Dental Coverage Associated with Dentist Visits, Well-Being
Dental coverage is also a significant factor in dental visits and overall well-being. Nearly eight of 10 Americans (78 percent) with dental coverage visit the dentist at least once a year versus only about half (52 percent) who don’t have coverage.
“The connection between dental coverage and dental visits perhaps isn’t surprising, but the numbers demonstrate the stark contrast in dental care,” Kohn says. “At Delta Dental, we strongly encourage those with coverage – and those without – to get the preventive care they need.”
In addition, Americans who have dental coverage are 14 percent more likely to say their overall well-being is good or better compared to those without dental coverage.

Reported Oral Health is Generally Strong
Half of Americans rate their oral health as very good or excellent, according to the Delta Dental study. Only 19 percent of Americans rate their oral health as fair or poor. Stronger reported oral health is linked with income, education and age. Younger Americans – those ages18 to 24 and those ages 25 to 44 – are more likely to rate their oral health highly than older Americans.
Despite the relatively strong oral health findings, several oral health challenges remain:
n  More than one of four Americans (27 percent) say they have open oral health issues that they’d like to resolve. The biggest reason for not addressing the problem is ability to pay for the work (cited by 62 percent of those with unresolved issues), while nearly a quarter (23 percent) mentioned fear of the treatment.
n  More than one of five Americans (21 percent) say they have been advised by a dentist that they have gum disease.
n  About one of six Americans (16 percent) say they have missed work due to oral health issues beyond regular treatments and cleanings.
“Delta Dental sponsored the Oral Health and Well-Being Survey to shine a spotlight on the importance of oral health in America,” says Kohn. “As leaders in dental benefits, we know the importance of oral health for basic daily activities involving the mouth and the link between oral health and overall health. This study’s findings demonstrate the vital role that dental care plays in overall well-being.”

Bonding performance of universal adhesives in different etching modes.


Available online 6 May 2014




The aim of this study was to compare the microtensile bond strength (μTBS) and resin penetration into dentin of three universal adhesives (UAs) applied in two different etching modes (i.e. self-etch or etch-and-rinse). The effect of thermocycling on the μTBS was also evaluated.


The occlusal third of sound human molars was removed and the exposed surfaces were treated with three UAs (Futurabond Universal, Scotchbond Universal Adhesive and All-Bond Universal) in self-etch or etch-and-rinse mode. Two one-step self-etch adhesives (Futurabond DC and Futurabond M) were applied on additional teeth as reference. After composite build up, the specimens were stored for 24 hours in distilled water at 37° C or thermocycled for 5000 cycles. Composite/dentin beams were prepared (1 mm2) and μTBS test was performed. Data was analyzed using three-way ANOVA and Tukey's test (α=0.05). One additional tooth was prepared for each group for evaluation of infiltration ability into dentin by dyeing the adhesives with a fluorochrome (Rhodamine B). After longitudinal sectioning, the generated interfaces were examined under confocal light scanning microscopy.


The addition of an etching step did not significantly affect the μTBS of none of the UAs, when compared to their self-etch application mode. All pre-etched specimens showed considerably longer resin tags and thicker hybrid layers. Thermocycling had no significant effect on the μTBS of the UAs.


Application of an etching step prior to UAs improves their dentin penetration, but does not affect their bond strength to dentin after 24 h or after thermocycling for 5000 cycles.
Clinical Significance: Similar bond strength values were observed for the UAs regardless of application mode, which makes them reliable for working under different clinical conditions.

Impact of oral mucosal conditions on oral health-related quality of life in preschool children: a hierarchical approach

International Journal of Paediatric Dentistry 2014;


To determine the impact of oral mucosal conditions on OHRQoL in preschool children.


A cross-sectional study was carried out with a selected representative sample of 724 children aged 2–5 years and their parents/caregivers. Data were collected through interviews with parents/caregivers, who also answered the B-ECOHIS. A clinical oral examination was performed to determine oral mucosal conditions, dental caries, dental trauma, and malocclusion. Data analysis involved descriptive statistics, the Kolmogorov–Smirnov normality test, the Mann–Whitney U-test and hierarchically adjusted Poisson regression models (< 0.05, 95% CI).


The prevalence of oral mucosal conditions was 50.7%, the most prevalent of which were melanotic macules (17.8%), oral ulcers (11.0%), Fordyce's spots (9.4%), geographic tongue (5.2%), fissured tongue (1.9%), median rhomboid glossitis (1.8%), and fistula (1.4%). In the final multivariate model, child with 5 years of age (RR = 1.60; 95% CI: 1.08–2.38; = 0.020), with presence of fistula (RR = 1.94; 95% CI: 1.27–2.95; = 0.002), and with dental caries (RR = 2.58; 95% CI: 2.00–3.35; < 0.001) had a negative impact on children's OHRQoL.


Child with 5 years of age, presence of fistula, and dental caries were associated with a negative impact on the quality of life of preschool children.

Prevention of dentine erosion by brushing with anti-erosive toothpastes


Available online 2 April 2014


This in vitro study aimed to investigate the preventive effect of brushing with anti-erosive toothpastes compared to conventional fluoride toothpaste on dentine erosion.

Materials and methods

Bovine dentine specimens (n = 12 per subgroup) were eroded in an artificial mouth (6 days, 6 × 30 s/day) using either citric acid (pH:2.5) or a hydrochloric acid/pepsin solution (pH:1.6), simulating extrinsic or intrinsic erosive conditions, respectively. In between, the specimens were rinsed with artificial saliva. Twice daily, the specimens were brushed for 15 s in an automatic brushing machine at 2.5 N with a conventional fluoride toothpaste slurry (elmex, AmF) or toothpaste slurries with anti-erosive formulations: Apacare (NaF/1% nHAP), Biorepair (ZnCO3-HAP), Chitodent (Chitosan), elmex Erosionsschutz (NaF/AmF/SnCl2/Chitosan), mirasensitive hap (NaF/30% HAP), Sensodyne Proschmelz (NaF/KNO3). Unbrushed specimens served as control. Dentine loss was measured profilometrically and statistically analysed using two-way and one-way ANOVA followed by Scheffe‘s post hoc tests. RDA-values of all toothpastes were determined, and linear mixed models were applied to analyse the influence of toothpaste abrasivity on dentine wear (p < 0.05).


Dentine erosion of unbrushed specimens amounted to 5.1 ± 1.0 μm (extrinsic conditions) and 12.9 ± 1.4 μm (intrinsic conditions). All toothpastes significantly reduced dentine erosion by 24–67% (extrinsic conditions) and 21–40% (intrinsic conditions). Biorepair was least effective, while all other toothpastes were not significantly different from each other. Linear mixed models did not show a significant effect of the RDA-value of the respective toothpaste on dentine loss.


Toothpastes with anti-erosive formulations reduced dentine erosion, especially under simulated extrinsic erosive conditions, but were not superior to a conventional fluoride toothpaste.

Carestream Dental Introduces Updated, Low-dose CS 9300 and New CS Model at American Association of Orthodontists Annual Session

Product Launches Further Company’s Position as a Key Player
in the Orthodontic Industry
NEW ORLEANS – Carestream Dental today introduced two new products at the American Association of Orthodontists (AAO) Annual Session, being held today through Tuesday, April 29, at the Ernest N. Morial Convention Center in New Orleans. These products include an updated version of the CS 9300 multi-modality imaging system that effectively scans patients using a lower radiation dose and new CS Model digital design software that can be used to create orthodontic appliances.
The new version of the CS 9300 captures diagnostic images at a lower radiation dose. Covering a wide scope of clinical needs with 3D, 2D and optional one shot cephalometric imaging capable of capturing images in just over a second—and also features five field of view sizes; auto-landmark detection; and lateral, oblique, frontal (AP/PA), submento-vertex and carpus views—for orthodontic practices, the CS 9300 with Fast Scan decreases the amount of radiation required to capture an image. The system features 3D imaging with up to seven selectable fields of view, ranging from 5 cm x 5 cm to 17 cm x 13.5 cm, plus 2D digital panoramic imaging with variable focal trough technology. Existing CS 9300 customers will have the option to upgrade their current unit to include the Fast Scan capability for lower radiation dose.
“From its adaptable fields of view to easy patient positioning, the CS 9300 really is the all-in-one system that clinicians need in their practice,” said Matt Hendrickson, U.S. orthodontic director for Carestream Dental. “This lower dose version reflects our commitment to aligning our products with the ALARA Principle. Now, practitioners can get quality images while providing their patients with greater protection from radiation exposure.”
CS Model is Carestream Dental’s first CS Solutions CAD (Computer Aided Design) product designed with orthodontists in mind. Combined with Carestream Dental’s 3D scanning solutions, CS Model software enables practitioners to quickly create digital models; review and store them electronically; and produce orthodontic appliances through preferred labs.
Once digital impressions are captured with an intraoral scanner, such as the CS 3500 of the CS Solutions portfolio, or traditional impressions are scanned with a cone beam computed tomography (CBCT) imaging system, such as the CS 9300 or CS 9000 3D, orthodontic practices can use CS Model. The software takes basic distance measurements including overjet, overbite, pressure map, arch length, tooth size, crowding measurement and more, to further improve clinicians’ diagnostic capabilities. CS Model integrates seamlessly with Carestream Dental’s orthodontic imaging portfolio and CS OrthoTrac software, as well as other leading practice management software. The software is also compatible with other open CAD/CAM systems that produce orthodontic appliances.
CS Model eliminates the need to make and store physical plaster models, saving valuable time and space for practices. This environmentally friendly solution also ensures that patients’ models are not damaged, lost or mixed-up over time. CS Model gives practices access to all cases 24/7, without the need to access third-party storage via the Internet.
AAO Annual Session attendees are encouraged to visit Carestream Dental’s booth number 1605 to learn more about the updates to the CS 9300 and CS Model, as well as ClearCorrect’s recent acceptance of digital scans from the CS 3500 intraoral scanner.
