Objective: Current acceptability, barriers to use, and clinical/teaching practices of Silver Diamine Fluoride (SDF) among Brazilian dentists were investigated. Material and Methods: A Google forms questionnaire was sent to dentists (n=10,500) to collect information about the use of SDF and the dentists' workplace, experience, specialty, and city of practice. A logistic regression model was performed. Results: From 409 respondents, 13.2% used SDF. Working at universities increased the use of SDF by 2.29 times (p=0.018) compared to private offices. Each training year, the chance of SDF usage increased by 3% (p=0.008). Pediatric dentists are more likely to use SDF (OR=6.76, p<0.001). There is no association between SDF usage and the city of practice. The majority (75.9%) indicated SDF for noncompliant patients. Dentists (75.9%) reported the exclusive use in deciduous teeth, while 24.1% also use in permanent teeth. The main barrier for non-users was a lack of knowledge (58.3%), while for users, tooth staining (90.7%) and parental acceptance (64.8%) were the complaints. Conclusion: The Silver Diamine Fluoride is not a common product used by the dentists from RJ. Its clinical applicability should be further disseminated; thus, lack of scientific knowledge would cease to be a problem in the use of SDF to arrest caries lesions.

Dental treatment resulted in significant improvement of the preschool children's OHRQoL.

Maus-tratos Infantis. Violência Doméstica. Odontopediatria. RESUMO Introdução: A violência doméstica contra as crianças interfere no seu desenvolvimento psicológico, levando a sequelas que se manifestam e persistem até a idade adulta. A evidência física da violência doméstica é facilmente observada no complexo orofacial e, eventualmente, é detectada pelos dentistas. Relato do Caso: Relatamos o caso de uma vítima de maus-tratos, de 9 anos de idade, que foi diagnosticada durante o tratamento odontológico. Um odontopediatra, durante as consultas de rotina, após identificar injúrias físicas (hematoma na órbita esquerda e queimaduras na mão esquerda e lábios), suspeitou tratar-se de maus tratos, levando o caso às autoridades responsáveis. A custódia da criança foi concedida à avó por uma decisão judicial, o que permitiu a recuperação da saúde e qualidade de vida. Conclusão: Os profissionais devem conduzir adequadamente os casos de abuso, a fim de proteger as crianças de ocorrências futuras.

Objective: To evaluate the efficacy of silver diamine fluoride (SDF) in arresting dentin caries lesions when applied under different concentrations and times. Material and Methods: Forty-two bovine blocks were selected and fixed in 24-well plates. Each well received a mixed bacterial inoculum added to the culture medium with 5% sucrose. The plates were incubated in microaerophilia (7 days) for caries formation, confirmed by micro-CT (M1). SDF was applied over the carious lesions for different times and concentrations (n=6): SDF 30% -immediate removal, 1 minute and 3 minutes; SDF 38%, -immediate removal, 1 minute and 3 minutes. The group without treatment was the control. Then, the samples were again scanned by micro-CT (M2) and submitted to a second cariogenic challenge for 21 days. Then, a final scan was performed (M3). Results: Mean pH at the culture medium and lesion depth were compared using Kruskal-Wallis and Wilcoxon tests. 38% SDF showed the lowest metabolic activity of the biofilm. All 38% groups and 30% 1 and 3 minutes did not show an increase in mean lesion depth comparing M3 with M1. However, only 30% 3 minutes and 38% 1 and 3 minutes showed a significant reduction of lesion depth. Conclusion:The minimum application time of 30% SDF to arrest dentin caries lesion was 1 minute, while 38% SDF arrested with application and immediate removal.
