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.

Multimorbidity and Depressive Symptoms and their Association with Self-Reported Health and Life Satisfaction Among Adults Aged ≥ 50 Years in Mexico.

Identify the association between multimorbidity and depressive symptoms (DS) with self-reported health (SRH) and life satisfaction in a national sample of Mexican ≥ 50 years older adults. Data are drawn from the Mexican Health and Aging Study (MHAS), a cross-sectional study conducted in 2018 involving 14,230 older adults aged 50 years and older living in urban and rural areas of Mexico. Depressive symptoms were measured using the Center for Epidemiological Studies depression scale (CES-D) and life satisfaction using the Life Satisfaction Scale (LSS), examined both as a categorical and continuous variable.

The use of the differential outcomes procedure for the recognition of facial expressions of complex emotions and its electrophysiological correlates.

The differential outcomes procedure (DOP) is an easily applicable method for enhancing discriminative learning and recognition memory. Its effectiveness in improving the recognition of facial expressions of emotion has been recently explored, with mixed success. This study aims to explore whether the expectancies generated via the DOP are reflected as differences in event-related potentials (ERPs) between participants in differential (DOP) or non-differential conditions (NOP) in a facial expression of complex emotion label task.

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.
