Abstract

This study determines the frequency and relationship between disk position and degenerative bone changes in temporomandibular joints in children and adolescent patients with internal derangement. Study design: TMJ, MRI of 88 patients were analyzed (average age: 14.7 years-old, range age: 10-18 years-old), female n=65 (73.9%) and male n=23 (26.1%). Images obtained were used to determine the frequency of disk position, joint effusion (JE) and degenerative bone changes (OA). Images were assessed by a calibrated radiologist (Kappa=0.82). Results: No significant association was found between disk displacement with reduction and degenerative bone changes (Chi2=9.894; OR= 0.375; p=0.0017), nor disk without displacement (Chi2=9.448; OR= 0.223; p=0.0021). A significant association was found between disk displacement without reduction and degenerative bone changes (Chi2=30.951; OR=6.304; p=0.0001). Conclusions: There is a significant association between disk displacement without reduction and degenerative bone changes (p=0.0001) in children and adolescent patients with TMD.
