Background Temporomandibular disorder (TMD) is a disorder with many possible etiologies (age, gender, ethnicity, parafunctional habit, etc.) and can cause degenerative bone change on the head of the condyle. It is best seen by cone beam computed tomography (CBCT). Objectives This study aimed to assess the effect of gender on the degenerative bone change of the condyle and joint space. Materials and Methods a prospective study of 97 study groups (194 TMJ) aged (20-50) The study group was TMD patients selected according to diagnostic criteria of temporomandibular disorder DC/TMD, and the study group were divided into two subgroups (Male and female). Then CBCT was taken and measured for the patient. The condyle degeneration was classified into (Flattening, erosion, osteophyte, and sclerosis. Results There was no significant difference between degenerative bone change (flattening. Erosion, and osteophyte) and genders. A significant difference, however, was found between genders in sclerosis and joint space. Conclusion TMD affects females more than males. Males have more joint space than females, and females have more degenerative condylar bone change compared to males, Erosion and flattening were the most frequent degenerative change in the condyle, and sclerosis was more frequent in females. Also, joint space in females was narrower than in male
