Dental disease before radiotherapy in patients with head and neck cancer
Member Price: $5.00
CE Credit(s): 1
Retail Price: $40.00
Course Created on: 12/01/2017
Description:

December 2017
No evidence-based guidelines exist for preventive dental care before radiation therapy (RT) in patients with head and neck cancer (HNC). An ongoing multicenter, prospective cohort study, Clinical Registry of Dental Outcomes in Head and Neck Cancer Patients (OraRad), is addressing this knowledge gap. The authors evaluated the level of dental disease before RT in the OraRad cohort, factors associated with dental disease, and dental treatment recommendations made before RT. As part of OraRad, the authors assessed caries, periodontal disease, dental recommendations, and dental interventions performed before RT.

Key Words. Radiation therapy; dentistry; caries; periodontal diseases; head and neck neoplasms.

December 2017
The authors updated a previously published systematic review to assess the effects of low-level laser therapy (LLLT) on reducing complications after the removal of impacted mandibular third molars. The authors searched for randomized clinical trials in which the investigators evaluated the efficacy of LLLT compared with that of placebo or no treatment. Two reviewers independently screened studies, extracted data, and assessed risk of bias. The authors used random effects model meta-analysis and the Grading of Recommendations Assessment, Development and Evaluation approach to rate the certainty of evidence.

Key Words. Impacted mandibular third molar; systematic review; postsurgical complications; pain; swelling; trismus.

Surface characteristics and lesion depth and activity of suspicious occlusal carious lesions
Member Price: $5.00
CE Credit(s): 1
Retail Price: $40.00
Course Created on: 12/01/2017
Description:

December 2017
A lesion on an occlusal tooth surface with no cavitation and no radiographic radiolucency but in which caries is suspected owing to surface roughness, opacities, or staining can be defined as a suspicious occlusal carious lesion (SOCL). The authors’ objective was to quantify the characteristics of SOCLs and their relationship to lesion depth and activity after these lesions were opened surgically. Ninety-three dentists participated in the study. When a consenting patient had an SOCL, information was recorded about the tooth, lesion, treatment provided, and, if the SOCL was opened surgically, its lesion depth. The Rao-Scott cluster-adjusted c2 test was used to evaluate associations between lesion depth and color, roughness, patient risk, and luster.

Key Words. Evidence-based dentistry; carious lesions; dentin.

Establishing the association between nonnutritive sucking behavior and malocclusions
Member Price: $5.00
CE Credit(s): 1
Retail Price: $40.00
Course Created on: 12/01/2016
Description:

December 2016
The authors studied the effects of nonnutritive sucking behavior (NNSB) on malocclusions through a systematic review of association (etiology). The authors performed a 3-step search strategy, including electronic searches. Studies of healthy participants with a history of active or previous NNSB, for whom specific malocclusion outcomes had been assessed, were eligible for inclusion. The authors considered before-and-after studies, prospective and retrospective (longitudinal) studies, case-control studies, and analytical cross-sectional studies. They excluded reviews, text and opinion-based articles, conference abstracts, case reports, case-series, and descriptive cross-sectional studies. The authors, using standardized instruments, independently assessed methodological quality and extracted data from the included studies. In situations for which there were sufficient studies, the authors conducted meta-analyses using the random-effects model, supplemented with the fixed-effects model in situations for which statistical heterogeneity was less than 50%, which the authors assessed using the I2 statistic.

December 2016
Because of the many possibilities for endodontically restoring the posterior teeth and the high prevalence of restoration failures, this topic continues to be of major concern. A composite resin (CR) restoration reinforced by a horizontal fiberglass post may improve the fracture resistance of endodontically treated teeth. The authors investigated this possibility by comparing the fracture resistance of molars restored with direct techniques with that of molars restored with indirect techniques. The authors divided 50 extracted sound third molars into 5 groups: sound teeth, onlay (ON), inlay (IN), direct CR, and transfixed fiberglass post (TFP) plus direct CR. The authors performed standardized mesioocclusodistal cavity preparations and endodontic treatments. The authors cemented indirect restorations of Lava Ultimate (3M ESPE) adhesively in the ON and IN groups. The authors restored CR group teeth directly with Filtek Z230 XT (3M ESPE). In the TFP group, the authors transfixed 2 fiberglass posts horizontally and restored the teeth directly with CR. Thereafter, the authors submitted the teeth to cyclic fatigue loading with 500,000 cycles at 200 newtons. The authors tested fracture resistance in newtons in a universal testing machine. The authors analyzed data with 1-way analysis of variance and a Tukey test (P < .05).

Dental disease patterns in methamphetamine users
Member Price: $5.00
CE Credit(s): 1
Retail Price: $40.00
Course Created on: 12/01/2015
Description:

December 2015
The authors used a large community sample of methamphetamine (MA) users to verify the patterns and severity of dental disease and establish a hierarchy of caries susceptibility by tooth type and tooth surface. Using a stratified sampling approach, 571 MA users received comprehensive oral examinations and psychosocial assessments. Three calibrated dentists characterized dental and periodontal disease by using National Health and Nutrition Examination Survey protocols. The authors also collected data on substance use history and other attributes linked to dental disease.

To determine the effectiveness of a mobile phone–based remote oral cancer surveillance program (Oncogrid) connecting primary care dental practitioners and frontline health care workers (FHW) with oral cancer specialists. The study population (N = 3,440) included a targeted cohort (n = 2,000) and an opportunistic cohort (n = 1,440) screened by FHW and dental professionals, respectively. The authors compared the screening efficacy in both groups, with specialist diagnosis considered the reference standard. The outcomes measured were lesion detection and capture of interpretable images of the oral cavity.

Repair or replacement of restorations
Member Price: $5.00
CE Credit(s): 1
Retail Price: $40.00
Course Created on: 12/01/2015
Description:

December 2015
A prospective cohort study that included dentists in The National Dental Practice-Based Research Network was conducted to quantify 12-month failures of restorations that were repaired or replaced at baseline. The study tested the hypothesis that no significant differences exist in failure percentages between repaired and replaced restorations after 12 months. It also tested the hypothesis that certain dentist, patient, and restoration characteristics are significantly associated with the incidence of restoration failure. Dentists recorded data for 50 or more consecutive defective restorations. The restorations that were either repaired or replaced were recalled after 12 months and characterized for developing defects.

Description:

November 2016
The aim of this systematic review was to answer the focused question, “In adults, is there any association between sleep bruxism (SB) and alcohol, caffeine, tobacco, or drug abuse?” This systematic review included studies in which the investigators assessed SB diagnosis by using questionnaires, clinical assessment, or polysomnography and evaluated its association with alcohol, caffeine, tobacco, or drug abuse. The authors graded SB as possible, probable, or definitive. The authors developed specific search strategies for Latin American and Caribbean Health Sciences Literature, PsycINFO, PubMed, ScienceDirect, and Web of Science. The authors searched the gray literature by using Google Scholar and Pro-Quest. The authors evaluated the methodological quality of the included studies by using the Meta-Analysis of Statistics Assessment and Review Instrument.
