Tooth wear and sleep quality: A study of police officers and non-police officers

Abstract

Abstract Objective: A cross-sectional study was performed to assess the prevalence of tooth wear facets and sleep disorders. Methods: The sample was divided into two groups: Group I: police officers (n = 144), and Group II: industrial workers (n = 142). A self-reported questionnaire, a clinical examination recorded in the dental records, and the Brazilian version of the Pittsburgh Sleep Questionnaire Index were used for data collection. Descriptive analysis, chi-squared and multiple logistic regression were used as statistical tests at a 5% significance level. Results: Group I was almost twice as likely to have tooth wear facets as was Group II (OR = 1.88 95% CI = 1.03–3.44). Sleep disorders were worse among the participants of Group I. Conclusions: The type of profession exerted an influence on sleep disorders and the presence of wear facets among the groups, with police officers most likely to suffer from these disorders.
