December 2017No 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

December 2017The 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.
December 2017A 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;
December 2016The authors of this study evaluated the effects of
lasers on the outcome of direct pulp capping by means of a meta-analysis. The
authors completed a literature search on PubMed, Cochrane Library, Embase, and
China National Knowledge Infrastructure, as well as a manual search of the
reference lists of all identified articles since the introduction of lasers in
endodontics in 1971 through May 30, 2016. The authors systematically evaluated
the studies that met the inclusion criteria and performed a meta-analysis.
December 2016The 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 2015The 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
December 2015To 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 =
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.
December 2015A 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
November 2016The 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.
