| Popis: | Introduction: In studies on the prevalence of tooth wear, few publications related to young adults are found. Objectives: To explore the associations of behavioral, medical, and socio-demographic variables with prevalence and severity of tooth wear of the whole dentition, in a sample of young adults, using a modified version of the Tooth Wear Index (TWI). Methods: Sample consisted of 116 university dental students with an average age of 23 years, who answered a questionnaire related to sociodemographic variables, self-perception and health behaviors. In addition, individuals underwent a clinical evaluation of tooth wear by one trained examiner using the TWI modified by Smith and Knight. Logistic regression was carried out at individual level. Results: A total of 9,906 dental surfaces in 116 individuals were examined, 72.27 % dental surfaces had no tooth wear (grade 0), but all individuals had at least one worn surface. Among the individuals, 78,4 % had grade 1 (enamel) as the highest level and 21.6% grade 2 (dentin) as the highest level. The presence of grade 2 tooth wear was mainly prevalent in the following individuals: male; smoker; with bruxism, and among those who reported having undergone orthodontic treatment. Analyzing the relevant factors that affect tooth wear by multiple regression analysis, it was found that smoking (OR 6.67; IC 1.73- 25.76) and bruxism (grinding) (OR 4.05; IC 1.29- 12.7) had the greatest effect on tooth wear. Conclusions: Our results suggest that being male, being a current smoker, having grinding bruxism and having previous orthodontic treatment are associated with tooth wear. |
