Unusual Findings in Trials Evaluating Adjuncts to Scaling and Root Planing: Meta-analysis (Part 1).

Background: A number of studies in patients with periodontitis have compared scaling and root planning (SRP) combined with an adjunctive treatment to SRP alone. Within that literature, an array of studies with overlapping investigators has consistently yielded substantially greater effects of adjunctive treatments than had been previously noted. This report investigates discrepancies between that cluster of research and the most recent American Dental Association (ADA) systematic review.

Unusual Findings in Trials Evaluating Adjuncts to Scaling and Root Planing: Reporting Quality (Part 2).

Introduction: On the topic of adjuncts to scaling and root planing (SRP), numerous randomized clinical trials (RCTs) were published by a single group of authors and frequently reported unusually large effect sizes. A meta-analysis in part 1 of this project failed to explain the causes for these unusual findings. We assessed the reporting quality and trial registration discrepancies to examine the possibility of replicating the work of this research group as well as the overall rigor of the research methodology.

Desquamative gingivitis: a challenging diagnosis for clinicians.

Introduction Diagnosis of underlying causes for desquamative gingivitis (DG) is often delayed in clinical settings, but little is known about factors influencing its delayed diagnosis. We investigated the diagnostic patterns and associated factors in a cohort of patients presenting primarily with DG.Materials and methods A total of 41 patients presenting primarily with DG were interviewed to evaluate professional and patient diagnostic delays.

Reporting quality and spin in abstracts of randomized clinical trials of periodontal therapy and cardiovascular disease outcomes.

Objective: Poor reporting in randomized clinical trial (RCT) abstracts reduces quality and misinforms readers. Spin, a biased presentation of findings, could frequently mislead clinicians to accept a clinical intervention despite non-significant primary outcome. Therefore, good reporting practices and absence of spin enhances research quality.

Medical reliability of a video-sharing website: The gingival recession model.

Objectives: To evaluate the quality of the scientific/clinical information in dentistry delivered by videos hosted by a popular video-sharing website.

Methods: The gingival recession condition was used as a model and YouTube™ as the video hosting service. A systematic observation of videos containing information on gingival recession was conducted.
