Prevalence of tooth erosion and associated factors in 11‐14‐year‐old Brazilian schoolchildren

摘要: Objective: Prevalence data about tooth erosion has attracted increasing attention in the dental community; however, population-based studies that assessed impact of demographic, socioeconomic, and dietetic predictors on are scarce. This investigation prevalence this condition a sample 11-14-year-old schoolchildren etiological factors. Method: A cross-sectional study multistage random 944, Brazilian was conducted Santa Maria, Brazil. We recorded severity erosion, caries, enamel hypoplasia. Socioeconomic habits/dietetic were collected by structured questionnaire. Data analyzed using Poisson regression model taking into account cluster sample. Results: low (7.2%). The most affected teeth maxillary incisors. Labial surfaces more often than palatal ones. All erosive lesions observed confined to enamel. Older children [prevalence ratio (PR) = 1.71; 95% confidence interval (CI): 1.06-2.76] with hypoplasia (PR = 1.98; CI: 1.21-3.22) likely have erosion. No significant association between habits dietary patterns, socioeconomic factors. Conclusion: suggest associated age presence It may indicate need strategies diagnose early stages minimize consequences.
