Temporomandibular disorders and psychosocial status in osteogenesis imperfecta - A cross-sectional study

Background Osteogenesis Imperfecta (OI) is characterized by a number of deviations in the orofacial region. The aims of the present study were to investigate the occurrence of temporomandibular disorders, to evaluate the psychosocial status, and to assess the dental occlusion in a population of adult OI patients. Methods Participants (n = 75) were classified with mild OI, type I (n = 56), or moderate-severe OI, type III and IV (n = 19). OI patients were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (axis I and II). Results Temporomandibular disorders and functional limitations in the orofacial region were rare and did not differ between patients with mild and moderate-severe OI (P > 0.050). No significant differences between Graded Chronic Pain Scale grades 0, 1, and 2 were found in mild OI vs. moderate-severe OI (P > 0.160). Few patients (16%) had signs of depression, but close to half (48%) had signs of somatization. Patients with moderate-severe OI had a lower mean number of teeth compared to patients with mild OI (P
