RESUMO
OBJECTIVE: To explore the presence and severity of temporomandibular disorders (TMD) signs and symptoms in a Turkish pediatric population, as well as their relationship to parafunctional behaviors, bruxism, malocclusion, anxiety, and sociodemographic traits. METHODS: A cross-sectional study was conducted with patients between the ages of 5-15. Demographic variables, TMD signs and symptoms, parafunctional habits, bruxism, and malocclusion were evaluated by clinical examination. Fonseca Anamnestic Index (FAI) was used to determine the presence and severity of TMD. State-Trait Anxiety Scale for Children (STAI-C) was used to evaluate the anxiety. Student t, Mann-Whitney U, chi-square tests, and logistic regression were used for statistical analysis. RESULTS: One hundred sixty-two participants (85 girls, 77 boys) with a mean age of 10.03 ± 1.88 years were included. The frequency of the participants who reported signs/symptoms of TMD was 19.7% according to FAI scores. Logistic regression analysis with the associated factors showed a significant relationship between the presence of the signs/symptoms of TMD and parafunctional habits (OR 4.24, 95% CI 1.64-10.93), and the presence of signs/symptoms of anxiety (OR 1.09, 95% CI 1.02-1.16). CONCLUSIONS: Children and adolescents who exhibit parafunctional behaviors and anxiety had a higher likelihood of having TMD signs/symptoms of varying degrees of severity.
