Abstract

Objectives: To verify the relationship between tooth brushing frequency and associated factors using new perspectives of health data analysis. Materials and methods: A cross-sectional study was conducted with data collected from the Brazilian National School Health Survey 2015 (PeNSE), we used multilevel and multivariate Poisson regression and classification tree analysis data mining technique. Results: 10,231 students  participated in the study, of which 51.3% were female students aged 13 to 18 years. In the multivariate and multilevel analysis, association between frequency of brushing and non-living in a state capital (PR=1.03) was verified; being female PR=1.06); race PR=1.02); age; and live in houses with up to 4 people PR=1.03). In the classification tree analysis, gender was the variable with the highest weight of discrimination. Conclusions: several factors were associated with the tooth brushing and it is expected that the data will subsidize public policies on the issue.
