Abstract


Objectives: To investigate the association between oral parafunctions, personality traits, anxiety and signs and symptoms of temporomandibular disorders in the adolescents.

Methods: Two hundred and seventy adolescents were examined clinically for the signs and symptoms of temporomandibular disorders. Participants completed questionnaires about demographic variables, medical history, symptoms of temporoman- dibular disorders, parafunctional oral habits, Minnesota Multibasic Personality Inventory, and Spielberger State-Trait Anxiety Inventory.

Results: Logistic regression analyses revealed that bruxism was associated with joint tenderness (Odds ratio (OR)=6.38, p < 0.01), joint noises (OR=6.02, p < 0.01) and masticatory muscle tenderness (OR=4.19, p < 0.05) to palpation. State anxiety showed increased risk of joint tenderness (OR=2.47, p < 0.05) and muscle tenderness (OR=3.25, p < 0.05) to palpation.

Conclusion: Within the limitations of this study, it was concluded that oral parafunctions, especially bruxism, state anxiety, de- pression and hysteria were associated with signs and symptoms of temporomandibular disorders in adolescents.

Keywords: Oral parafunctions, personality traits, signs and symptoms of temporomandibular disorders, adolescents.
