Surface characteristics and lesion depth and activity of suspicious occlusal carious lesions

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.

Efficacy of adjuvant laser therapy in reducing postsurgical complications after the removal of impacted mandibular third molars

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.

Dental disease before radiotherapy in patients with head and neck cancer

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.

Benefits and harms of capnography during procedures involving moderate sedation

Patient safety is a priority in dentistry. Evaluating the benefits and harms associated with the addition of capnography to standard monitoring during moderate sedation for adult patients in the dental practice setting is needed. The authors used rapid review methodology to identify relevant systematic reviews, which they updated through a systematic search by using the same search strategy as the identified reviews. The authors searched PubMed and Google Scholar and through the references of the identified systematic reviews, which yielded 2,892 studies. Inclusion criteria were that the article was available in English, was original research in adult humans who had undergone moderate procedural sedation, and involved comparing standard monitoring with the addition of capnography.

Key Words. Capnography; moderate sedation; procedural sedation; hypoxemia; respiratory events; sedation quality.

Clinical accuracy data presented as natural frequencies improve dentists’ caries diagnostic inference

The authors assessed whether dentists’ diagnostic inferences differ when test accuracy information is communicated using natural frequencies versus conditional probabilities. A parallel, randomized controlled trial with dentists was carried out in Rio de Janeiro, Brazil. The dentists received a question on the probability of a patient having interproximal caries, given a positive bite-wing radiograph. This question was asked using information that was formulated into either natural frequencies or conditional probabilities.

Key Words. Diagnosis; communication barriers; persuasive communication; health education; risk; probability.

Assessing dentists’ human papillomavirus-related health literacy for oropharyngeal cancer prevention

Oropharyngeal cancers related to human papillomavirus (HPV) are on the rise. Dentists may be the next group of providers articipating in the prevention of HPV. The aim of this study was to assess dentists’ health literacy regarding the connection of HPV and oropharyngeal cancer. The authors conducted 4 focus groups with dentists (N = 33) during a regional dental conference in 2016. Guided by the health literacy competencies (that is, access, understand, appraise, and apply), the authors used constant comparison methods for data analysis.

Key Words. Human papillomavirus; HPV-related oropharyngeal cancer; dentists; health literacy; HPV vaccine.
