Taub Products Announces Release of New Eyewash station



Jersey City, NJ: June 22, 2017 - TAUB Products, a long-time manufacturer of dental laboratory and restorative products, has introduced a low-profile emergency eyewash station that adapts to a wide range of office and laboratory faucets. The new station provides instant access to a single aerated water jet, flushing the eyes and washing the face of chemical or particulate contamination.

Jordan Taub, Vice President of TAUB, stated, “The unique design allows water to flow normally downward for washing hands, and during an emergency, the user can quickly rotate it upwards, providing a soft stream of water that will wash the face. The user places the water stream on the brow of the nose and both eyes receive an effective rinse.”

Setting this apart from dual-jet designs, the key features of the product include a single rotating nozzle to wash eyes and face, a low-profile modern design that fits most standard faucets, a flow rate of 1.2 gallons per minute, which exceeds ANSI standards, and a design that prevents standing water, thus reducing the chance for mold development.

TAUB Products is celebrating its 65th year in business. TAUB provides innovative, high-quality solutions for dental professionals. For more information on TAUB and its products, call 800-828-2634, or go to www.taubdental.com.

A Novel Evidence-Based Periodontal Prognosis Model

,

Abstract

Objective

Patients with periodontal disease and the dental professionals responsible for their care want to know which teeth are expected to respond favorably to periodontal treatment and which teeth are likely to be lost in the short and long term. A number of different periodontal prognosis systems have been previously proposed but do not consider important patient-level factors, such as smoking and diabetic control, in the calculation of the expected outcome and often use subjective measures that introduce potential inaccuracies. The aim of this report is to translate the best available evidence on periodontal prognosis into a clinical model to facilitate decision-making and improve patient outcomes.

Methods

Criteria for an ideal prognostic system were proposed and used to assess the previously reported models. With an emphasis on the inclusion of patient-level modifiers (PLMs) and the exclusive use of objective parameters, a new evidence-based model was developed.

Results

This report proposes a new tooth-level prognosis model that uses 9 evidence-based quantifiable parameters to provide a prognosis of secure, doubtful, poor, or irrational to treat. Six tooth-level risk predictors (bone loss:age, pocket depth, furcation involvement, infrabony defects, anatomical factors, and mobility) and 3 PLMs (smoking, diabetes, and bleeding on probing) are used to determine the expected course of disease with specific reference to the suitability of the tooth for future dental treatment.

Conclusions

PLMs must be considered when determining the prognosis of a tooth with periodontal disease. The model proposed in this report is based on the best available evidence for factors affecting tooth survival and has been designed to be as simple and objective as possible to facilitate its adoption in clinical practice. It will be retrospectively and prospectively validated to determine its ability to accurately predict the course of disease.

Erbium Laser Technology vs Traditional Drilling for Caries Removal: A Systematic Review with Meta-Analysis



Abstract

Objective

The study aimed to assess the efficacy of erbium laser technology compared with traditional drilling for caries removal.

Methods

A systematic search was conducted through Medline via PubMed, Embase, Cochrane databases, CNKI till December 2016. Randomised controlled trials, quasi-randomized controlled trials, or controlled clinical trials with data comparing the efficacy of erbium laser technology versus traditional drilling for caries removal were included.

Results

Fourteen studies were selected in our meta-analysis. Erbium laser technology showed an increased time when removing caries compared with drilling (mean difference: 3.48, 95% confidence interval: 1.90-5.06, P < .0001). However, erbium laser technology reduced the requirement for local anesthesia (risk ratio: 0.28, 95% confidence interval: 0.13-0.62, P = .002). Erbium laser technology was also not significantly different to traditional drilling with regard to restoration loss, pulpal vitality, and postoperative sensitivity.

Conclusions

Erbium laser technology showed an increased time for cavity preparation compared with traditional drilling. However, erbium laser technology reduced the requirement for local anesthesia. There was no significant difference between erbium laser technology and traditional drilling regarding restoration loss, pulpal vitality, and postoperative sensitivity.

CAD/CAM-fabricated ceramic implant-supported single crowns made from lithium disilicate: Final results of a 5-year prospective cohort study


Abstract

Background

All-ceramic bilayer systems suffer from technique-sensitivity, resulting in increased technical complication rates. This might be overcome by monolithic reconstructions, facilitating digital workflows.

Purpose

To evaluate the clinical and patient-reported outcome of CAD/CAM-fabricated implant-supported single crowns (ISCs) made of lithium disilicate (LS2) cemented on ceramic implants 5 years after implant installation.

Materials and methods

Twenty-four patients were included in the study. All participants received a one-piece ceramic implant in anterior (4 incisors) and posterior regions (10 premolars, 10 molars). LS2 crowns were computer-aided designed (CAD), manufactured (CAM) and adhesively luted onto the implants. Follow-ups were performed yearly up to 60 months after implant installation. The survival/success rates of the restorations were calculated according to modified US Public Health Service criteria as follows: Clinically relevant defects that could be repaired intraorally were accepted for survival, whereas small-area chippings, roughness (ø < 2 mm), slightly soundable marginal gaps, minimal undercontours/overcontours, and tolerable color deviations were accepted for success. Kaplan-Meier plots were used for the success/survival analyses. Furthermore, patient-reported outcome measures (PROMs) were assessed by applying visual analog scales (VAS). Linear (PROMs) and logistic (USPHS criteria) mixed models were fitted to evaluate time effects on response variables.

Results

Twenty-two ISCs could be evaluated 55.2 ± 4.2 months after prosthetic delivery. Two patients were reported as drop-outs (1 died, 1 moved abroad). No failures were observed, resulting in 100% survival. At two ISCs, a major-roughness had to be treated. This resulted in a Kaplan-Meier success estimate of 91.7% (95%CI: 70.6%-97.9%). Compared with pretreatment, all surveys at prosthetic delivery except for self-esteem (P = .375) showed significantly improved VAS scores. No decrease in satisfaction could be observed over time until the end of follow-up (P ≥ .056).

Conclusion

Concerning survival/success rates and PROMs, the evaluated crown-implant system showed favorable mid-term results. To date, there are no comparable data available for implant-supported ISCs made of LS2.

Comparison of dimensional accuracy of conventionally and digitally manufactured intracoronal restorations


The Journal of Prosthetic Dentistry


Available online 2 June 2017

Abstract

Statement of problem

Advances have been made in digital dentistry for the fabrication of dental prostheses, but evidence regarding the efficacy of digital techniques for the fabrication of intracoronal restorations is lacking.

Purpose

The purpose of this in vitro study was to compare the dimensional accuracy of intracoronal restorations fabricated with digital and conventional techniques.

Material and methods

A sound mandibular molar tooth received a standard onlay preparation, and onlays were fabricated with 1 of 3 fabrication techniques. In group CC, the onlays were made after conventional impression and conventional fabrication of a resin pattern. In group CP, the onlays were made after conventional impression and 3-dimensional (3D) printing of the pattern. In group IP, the onlays were made after intraoral scanning, and 3D printing produced the resin pattern. Ten specimens in each group (N=30) were evaluated. Glass-ceramic restorations were fabricated using the press technique. The replica technique was used to assess the marginal fit. Each replica was assessed at 8 points. One-way ANOVA was used to compare the marginal discrepancy among the 3 groups. The Tukey honest significant differences test was applied for pairwise comparisons of the groups (α=.05).

Results

No significant differences were noted in the marginal discrepancy at the gingival margin among the 3 groups (P=.342), but significant differences were noted among the 3 groups in the pulpal (P=.025) and lingual (P=.031) areas. Comparison of the absolute discrepancy among the 3 groups revealed that only groups CC and CP were significantly different (P=.020) from each other.

The efficacy of non-narcotic analgesics on post-operative endodontic pain: A systematic review and meta-analysis



Summary

The objective of this review was to evaluate the efficacy of non-narcotic analgesics including non-steroidal anti-inflammatory drugs (NSAIDs) and/or paracetamol in the treatment of post-operative endodontic pain. Additionally, we aimed to examine the possible association of study covariates on the pain scores using meta-regression analysis. An electronic search was performed in 2016. After data extraction and quality assessment of the included studies (n = 27, representing 2188 patients), meta-analysis was performed using a random-effect inverse variance method. Meta-regression analysis was conducted to examine the associations between effect sizes and study-level covariates (P < 0·05). The results showed that administration of non-narcotic analgesic was more effective than placebo in the management of post-operative pain, resulting in a lower pain scores with a standardised mean difference of −0·50 (95% CI= −0·70, −0·30), −0·76 (95%CI= −0·95, −0·56), −1·15 (95% CI= −1·52, −0·78), −0·65 (95% CI= −1·05, −0·26) for immediately after the procedure, 6−, 12− and 24 h post−operative follow-ups (test for statistical heterogeneity: P = 0·000, P = 0·000, P = 0·000 and P = 0·001), respectively. Our meta-regression analysis provided the evidence for association between some study covariates with treatment effect, each at different follow-ups. We concluded that the clinicians can manage post-operative endodontic pain by administration of NSAIDs and/or paracetamol. However, analgesic regimens should be considered as important determinants when prescribing a pharmacological adjuvant.

Canadian Dentists Turn to Financial Practice Management CE, Patient Financing and Promotion on Social Media as Dental Practice Consolidation Continues



Toronto, ON – June 6, 2017 – The fundamental shift in the make-up of the Canadian dental practice detected in previous reports is continuing, according to results from the DIAC (Dental Industry Association of Canada) Twenty-First Annual Future of Dentistry Survey. All of the following points may reflect on the impact of the current economic situation on the dental practice in Canada:
  •   There are now more dentists per practice on average, with a record 13% of practices with five or more dentists. This was 3.4% in 2016 and an average of 6.3% the last 14 years.
  •   There are now more operatories per practice (72% of respondents had four or more operatories. Of these, an all-time high of 30% had five or more). Almost 1⁄4 (22%) of respondents were planning on adding at least one operatory in the next two years.
  •   The number of hygiene days per practice is increasing overall (44% of respondents in 2017 had 5 or more hygiene days per week, as compared to 40.4% last year and the average of 38.5% the last ten years).
  •   At the same time, the average number of patients treated per day continues to decline. While influenced by specialist respondents, on an overall basis, dentists treated 12 patients in an average day as compared to the average of 12.5 patients over the last ten years.83% stated they treated less than 15 patients a day (as opposed an average of 77.5% over the last four years).
    It is little wonder that “Getting More Patients” was the top challenge that respondents intended to address in 2017 (as well as the Top Metric for Success in the opinion of 83%), with “Financial/paying bills/overhead” a close second.
    Many dentists have responded by moving into Multi-practice (Group Practice). While the majority (59%) of respondents stated they were in a solo practice, more than a third (36%) were now in a group practice and a further 4% in Corporate dentistry. The two key advantages of a multi-practice structure attracting those who were in that type of practice were Associate Support (51%) and Buying Power (30%).
    Dentists are also now focusing their Practice Management CE activities on Financial aspects. While all four of the highest rated Practice Management topics for 2017 related to building the business of the practice (Ranked in order from highest: Revenue Enhancement/Expense Management; Fraud Protection, Marketing the Practice, and Communication/Case Presentation), the top focus has switched from Marketing to “the Numbers”, which may be a reflection on the economic situation. At the same time, member in Study Clubs was up overall; with 45.1% of respondents stated they belonged to one or more as compared to the average 37.9% of the previous eight years.
The majority (65%) of dental practices now offer patient financing in some fashion. Almost one-half (47%) of respondents offered in-house financing while 19% used third party financing.
Social Media continues to climb the list of Practice-Building Tools utilized at 45% of respondents, now second to “Asking for referrals” and progressively trending upward from 13% in 2012 when the question was first asked. This movement to on-line promotion mirrors where dental patients are telling practitioners they are getting information on dental treatment options. According to the survey, Internet achieved an all-time high rating and was ranked as the top patient source for the second straight year. This was followed by the more traditional sources of Family members, friends, etc. and Dentist/Dental Team presentations.
A total of 335 practicing Canadian dentists responded to this year’s survey with a good proportional distribution across all regions of the country. Based on this response rate, overall 2017 survey results have an accuracy of +/- 5.4% 19 times out of 20.
