Abstract
ABSTRACT Objective This study aimed to investigate the relationship between occlusal problems and hearing symptoms. Methods Electromyography, occlusion analysis, and hearing tests were performed on 24 patients with temporomandibular disorders and concurrent ear symptoms and 16 subjects in the control group. Results The null hypothesis of no statistically significant relationship between pure tone audiometry (PTA) values and disclusion times (DT) > 0.40 s and <0.40 s was rejected. There were statistically significant correlations between 0.25, 0.5, 1, 6, and 8 kHz airways of the right and left ear and 1 and 2 kHz bone conduction for disclusion times >0.40 s. Conclusion Reducing disclusion time to <0.40 s may ameliorate ear symptoms.
