Periapical and bitewing radiographs lack the sensitivity to reliably diagnose horizontal root fractures, and, therefore, asymptomatic teeth with root fractures may remain undetected for years. This article reports a case in which a patient presented with a mucogingival defect on tooth No. 24 with no apparent history of dental trauma. Read More

Child sexual abuse (CSA) is defined as inappropriate adolescent or adult sexual behavior or contact with a child. Sexual abuse may be committed by any person including those under the age of 18 years when that person is either significantly older than the victim or is in a position of power or control over the child. Detecting CSA requires a high incidence of suspicion and familiarity with physical, behavioral, and verbal indications of abuse. Read More

Amelogenesis imperfecta (AI) is a hereditary developmental disorder affecting the enamel of teeth. Affected patients present with tooth hypersensitivity, rapid tooth wear, or fractures of enamel as well as alterations in color and shape, all of which compromise esthetic appearance and masticatory function. Chronic conditions in childhood severely impact the whole family, affecting normal family routines and/or increasing the family's financial burden. Read More

Hydrolytic and enzymatic degradation by matrix metalloproteinases (MMPs) reduces the durability of composite resin restorations on caries-affected dentin (CAD). The use of MMP inhibitors such as epigallocatechin-3-gallate (EGCG) could increase the longevity of the bond to dentin. This study aimed to evaluate the use of EGCG at different aqueous concentrations on the resin-dentin microtensile bond strength (μTBS), fracture pattern and nanoleakage (NL) in immediate (IM) time interval and after 12-months of water storage (1Y) when using a two-step etch-and-rinse adhesive system on CAD.

Purpose: Adhesively luted partial ceramic crowns have been documented to be clinically more durable than direct composite restorations when minimally invasively restoring large defects (replacing two cusps or more) in posterior teeth. The clinical longevity of such restorations is largely determined by the tooth-preparation design, material selection and adhesive luting procedure. The most frequently recorded failure in medium- to long-term clinical trials is fracture of the restoration. Read More

In osteoporosis patients receiving antiresorptive medications, stopping the drug and delaying tooth extraction has been suggested to reduce the risk of osteonecrosis of the jaw (ONJ). However, postponing tooth extraction for ≥ 2 months was associated with an increased risk of delayed wound healing beyond 8 weeks after extraction, a risk factor for developing ONJ.

Introduction: A long waiting time before tooth extraction could result from concern about a potential increased risk of osteonecrosis of the jaw (ONJ) in osteoporosis patients. Read More
