We conducted a systematic review of epidemiological studies to assess the prevalence of distal surface caries (DSC) in second molars adjacent to third molars. We searched the Cochrane Library, Lilacs, Embase, and Medline through Ovid (Wolters Kluwer) to retrieve English and non-English papers from inception to June 2016, and supplemented this with a search of the references and by tracking citations. Three reviewers contributed: one reviewed all the papers, and the other two divided the rest between them. They extracted data, completed structured quality assessments with a validated risk of bias tool for observational studies, and categorised the summary scores. The search yielded 81 records and 11 studies were analysed. The considerable methodological diversity meant that five were not eligible for inclusion in the quantitative synthesis. A meta-analysis of six studies on the prevalence of DSC and a subgroup analysis of three on various third-molar angulations were indicated. The overall pooled prevalence estimate calculated with a random-effects model was 23% (95% CI 2% to 44%) among patients. Prevalence subtotals were 20% (95% CI 5% to 36%) for prospective, and 15% (95% CI 5% to 36%) for retrospective studies among teeth. A subgroup analysis of three studies with 1296 patients (1666 molars) yielded a prevalence of DSC of 36% (95% CI 5% to 67%) for mesial impactions and 22% (95% CI 1% to 42%) for horizontal impactions. DSC was present in 3% of distally-inclined impactions, (95% CI 1% to 5%) and in 7% (95% CI 1% to 13%) of vertical third molars. The studies varied. The risk of bias was low in one and moderate in two. European studies suggested that DSC may be present in about one in four referrals for the assessment of third molars, and that the risk is considerably higher in those with convergent third molar impactions.

Oral paresthesia occurs when one of the nerves in the region is injured, usually the inferior alveolar and/or lingual nerve, after dental procedures such as the extraction of lower third molars. The objective of this study was to describe the case of a patient who received photobiomodulation (PBM) therapy for paresthesia of the inferior alveolar nerve (IAN) caused by the extraction of mandibular third molars. The protocol used involved a super-pulsed diode laser with dual wavelengths of 810 nm and 980 nm, 1 W, 60 seconds, 12.

Introduction: Third molar removal is one of the most common surgical procedures in dentistry. Therefore, it is important to evaluate the learning curve of dentists undergoing surgical training. Thus, the aims of this study were to assess the performance of oral surgery residents in third molar extractions based on operative time and the occurrence of incidents/complications, and to determine which variables are associated with surgical difficulty.

The primary aim of this study was to determine whether there is a difference in degree of conversion (DC) between resin cements polymerized with an adhesive and those without an adhesive. The secondary aim was to compare interfacial gap of zirconia restoration when resin cements are self-cured. The DC of resin cement was measured without adhesive treatment continuously for 15 min and at 24 h.

Third molar radiographic assessment can help determine the probability of an individual reaching the legal age of majority, typically 18 years old. This study aims to assess this probability using third molar development through the Demirjian staging system. The sample consisted of 429 panoramic radiographs (210 females, 219 males) from individuals aged 15-23.

Background: The current study attempts to assess the impact of third molar impaction on external root resorption (ERR) of the adjacent second molars. We aimed to determine the prevalence, severity, and associated factors with ERR in a sample of panoramic radiographs.
Material And Methods: A retrospective cross-sectional study was carried out at teaching hospital.
