A structured questionnaire was developed and applied to collect information on participants' professional profiles, clinical indications, materials, techniques, and perceptions of pit and fissure sealants. The study outcomes were the positive perception of sealant use as: (a) a preventive measure, or (b) a therapeutic approach to carious lesions. Responses were dichotomized into positive perception (\"strongly agree\" or \"agree\") and negative perception (\"neither agree nor disagree,\" \"disagree\" or \"strongly disagree\"). Independent variables included sociodemographic, educational, professional, and technical characteristics. Multiple logistic regression models were used to analyze associations (p < 0.05). A total of 2,394 dentists participated in the study, 82.5% of whom had a positive perception of sealants for prevention, and 83.1%, for therapeutic purposes.

A sample of 2,102 male and female Brazilian children aged 3 to 10 years exhibiting good general health was examined by 30 calibrated dentists using WHO probes and clinical mirrors, using the index proposed by Ghanim et al.

Prevalence was assessed by calculating frequency, whereas etiologic factors were evaluated using univariate and multivariate Poisson logistic regression with robust adjustment. In addition, multivariate analysis was conducted using nonparametric resampling with Jacknife adjustment. The overall prevalence of hypomineralization in primary teeth was 18.5%, with second molars affected in 17% and canines in 6.7% of the cases, while other teeth were affected at lower rates. Exclusive breastfeeding for six months showed a protective effect against hypomineralization (p = 0.40). Children with HSPM were five times more likely to develop MIH, regardless of sex (OR: 4.92).

The roots were then divided into 3 groups according to retreatment procedures: Reciproc R25 followed by R40; Hyflex 25.04 followed by 40.04; ProDesign Duo Hybrid 25.06 followed by 40.05. The canals were irrigated with 1 mL 1% sodium hypochlorite, and a final rinse was performed with 5 mL 17% EDTA for 3 minutes.
