Abstract This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother’s schooling and malocclusion were associated with the number of sextants with bleeding. The mother’s schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

Abstract The aim of this cross-sectional study was to assess whether favorable factors related to school characteristics have a positive effect on the impact of traumatic dental injury (TDI) on oral health-related quality of life (OHRQoL). An epidemiological survey of oral health was conducted with 12-year-old schoolchildren from Quito, Ecuador. Children were examined for TDI, dental caries, and malocclusion. Individual socioeconomic data were also collected. Information on the physical environment, health practices, and occurrence of negative episodes at school was collected from the school coordinators. The Child Perceptions Questionnaire 11-14 (CPQ11-14) was used to evaluate the OHRQoL (outcome variable). Multilevel Poisson regression analysis was conducted. Severe TDI was associated with higher CPQ11-14 scores, even in the multiple model adjusted for oral health conditions, sex, individual socioeconomic variables, and school-related variables. Children from schools that had an appropriate tooth-brushing environment for their students exhibited a lower impact on OHRQoL, even after adjustment for the occurrence of TDI and other variables. A favorable school environment may exert a positive effect on OHRQoL, independent of the occurrence of TDI.

Objetivo: analisar, entre 2019-2021, as alterações quantitativas nas urgências odontológicas (UO) no Brasil e suas regiões. Materiais e Métodos: Dados coletados no Sistema de Informação em Saúde da Atenção Básica (SISAB) no período de 2019 a 2021. A representação das UO foi pelo abscesso dento-alveolar (ADA) e dor de dente (DD). O ano de 2019 foi o ano de controle (não pandêmico) e 2020-21 os de exposição. Os testes Friedman e Post-Hoc de Durbin-Conover utilizaram nível de significância de 5%. Os dados foram organizados pela diferença percentual para facilitar a análise. Resultados: Para o Brasil em 2021, a diferença percentual com 2019 sugerem que o ADA (-2,16%, p=1,0) e a DD (+14,94%, p=0,064) retomaram os valores, após a queda de 2020. A região Sul, em 2020, não teve queda em ADA (-5,48%, p=0,436) e DD (+3,7%, p
