INVESTIGATION OF THE RELATIONSHIP AMONG TEMPOROMANDIBULAR JOINT SUBLUXATION, JOINT SPACE AND ARTICULAR EMINENCE INCLINATION IN BENIGN JOINT HYPERMOBILITY SYNDROME

Objective: The objective of this study was a radiological examination of the articular eminence inclination and space of the temporomandibular joint in benign joint hypermobility syndrome (BJHS) patient who has temporomandibular joint subluxation (TMJS) and not subluxation. Material and Method: A hundred patients (50 females, 50 males) with BJHS who admitted to our clinic with the complaint of TMJ were included in the study. The eminence inclination and the joint space were measured on the cone-beam computed tomography (CBCT). Results: In our study, there was no statistically significant difference among subluxation and all measurements and age. However, there was the statistically significant difference only between gender and superior joint space (SS). The SS was higher in males (mean 3.60 mm) than females (mean 2.89 mm). There was found a statistically significant correlation between the SS and the age, bf (best-fit) angle, tr (top-roof) angle, posterior joint space (PS) (p<0.05). Conclusion: In patients with BJHS with and without subluxation, joint spaces [anterior joint space (AS), SS, PS and articular eminence inclination (determined by bf and tr angle) do not differ when the mouth is in the closed position.
