Surface characteristics and lesion depth and activity of suspicious occlusal carious lesions
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.
Efficacy of adjuvant laser therapy in reducing postsurgical complications after the removal of impacted mandibular third molars
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.
Dental disease before radiotherapy in patients with head and neck cancer
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.
The relationship between education debt and career choices in professional programs
The authors examined the relationship between education debt and career choice, particularly dentists’ decisions to specialize, participate in public health insurance programs, and join dental management service organizations (DMSOs). The authors used data from the American Dental Association 2015 office database, which contains dentist demographic information and identifies dentists who participate in public health insurance programs for pediatric dental care services. The authors merged this database with the 2002-2015 American Dental Association Survey of Dental Graduates, which contains information about education debt, to assess the relationship between education debt and career choices. The authors used probit and multinomial logit models to determine the relationships among education debt, demographic characteristics, and dentist career choices.
Intrapocket topical anesthetic versus injected anesthetic for pain control during scaling and root planing in adult patients
In this systematic review and metaanalysis, the authors evaluated the pain during scaling and root planing with use of topical anesthetic versus that with the use of injected anesthetic in adult patients. The authors searched 6 databases for randomized clinical trials in which the investigators compared the clinical effectiveness of intrapocket and injectable anesthetics. The primary outcome was the risk of developing pain or intensity of pain. Quality assessment followed the guidelines from the Cochrane Collaboration’s risk-of-bias tool. The authors performed meta-analyses on studies considered at low and unclear risk of bias.
Impression evaluation and laboratory use for single-unit crowns
Objectives were to determine the likelihood that a clinician accepts an impression for a single-unit crown and document crown remake rates. The authors developed a questionnaire that asked dentists about techniques used to fabricate single-unit crowns. The authors showed dentists photographs of 4 impressions and asked them to accept or reject each impression. The authors correlated answers with dentist and practice characteristics. Other questions pertained to laboratory use and crown remake rates.
Predicting extension of cracks to the root from the dimensions in the crown
In this study, the authors investigated whether extension of a tooth crack into the root can be predicted by the appearance of the crack in the crown in vitro. The authors obtained 22 cracked teeth from 22 patients who underwent extraction, and they scanned the teeth using microcomputed tomography. The length and width of the crack on the occlusal surface (LOS and WOS, respectively) and the length of the crack on the proximal surface (LCPS) were measured on 3-dimensional reconstruction images. The pulp chamber roof was penetrated and removed. A crack line visible under the microscope only on the access cavity wall rather than extending to the bottom of the pulp chamber was termed a “nonroot crack.” A crack seen at the bottom of the pulp chamber or root wall was termed a “root crack.” The authors analyzed the data using Pearson correlation coefficients and receiver operating characteristic curves.
