Scanning electron microscopy analysis of metallic and aesthetic bracket meshes before and after debonding.

Objective: To study the influence of bracket base meshes on shear bond strength and observe them using a scanning electron microscopy (SEM) before and after debonding.

Methods: Ninety brackets were divided into nine groups of 10 samples each: G1-Alexander, G2-Mini Sprint Brackets, G3-In-Ovation R CCO, G4-Gemini SL Self-Ligating Bracket, G5-Classic mini 2G Stylus, G6-Gemini Metal Brackets, G7-Clarity Advanced, G8-Crystall-Ize, and G9-Ceramic Series Flexx 2G. Groups G1 to G6 and G7 to G9 consisted of metallic and aesthetic brackets, respectively.

Prevalence and severity of dental caries using ICDAS in predicting treatment needs in Mexican school-age children.

Evaluate the prevalence and severity of caries in permanent teeth and their association with the treatment needs of 8-12-year-old Mexican schoolchildren. The cross-sectional study was conducted on 1139 8-12-year-old schoolchildren attending two public primary schools in State of Mexico. The study used the International Caries Detection and Assessment System (ICDAS) to examine the prevalence of caries and identify treatment needs in schoolchildren.
