Abstract

Temporomandibular joint dysfunction (TMJ) pain dysfunction syndrome is a multifactorial disease. Numerous studies have shown a relationship between the functional state of the TMJ, occlusion, and the musculoskeletal system. The aim of this study is to investigate the prevalence of TMJ disorders among students and compare their prevalence with occlusal factors and parafunctional habits.
Materials and methods.
A total of 155 volunteers with TMJ disorders were selected among students based on their complaints. CT scans of the TMJ were studied, and occlusal analysis was performed based on morphological and functional changes. Cases of teeth grinding and clenching were identified through questioning.
Results.
Myofascial pain was experienced by 18.2% of subjects, and 12.3% had joint disorder with disc displacement. Teeth clenching was not statistically associated with TMJ dysfunction (p≤0.01). In occlusal factors, overlap showed a statistically significant correlation only with myofascial pain. No association was found between functional change and TMJ dysfunction.

Key words:

myofascial pain syndrome, temporomandibular joint dysfunction, bruxism, dental occlusion
