ABSTRACT
OBJECTIVE: This cross-sectional study examined differences in orofacial features and oral health-related quality of life in previously treated young adults with either idiopathic condylar resorption (ICR) or TMJ involvement from juvenile idiopathic arthritis (JIA).
MATERIAL AND METHODS: The study included 17 patients with ICR and 15 patients with JIA-related TMJ involvement, all treated at the Section for Orthodontics, Aarhus University Craniofacial Clinic, Denmark and the Department of Oral and Maxillofacial Surgery, Aarhus University Hospital, Denmark. Data compared came from a standardised radiological examination with cone-beam computed tomography, a standardised clinical orofacial examination and a completed oral health-related quality of life questionnaire (OHIP-14). Validated methodologies were used to evaluate TMJ and dentofacial morphology.
RESULTS: The ICR patients reported a markedly higher number of TMJ pain symptoms, affected jaw function and difficulties in chewing food. The ICR group showed significantly more pronounced aberrant dentofacial morphology in relation to mandibular inclination, anterior/posterior face height ratio and mandibular sagittal position. No statistically significant differences were detected in the severity of condylar deformity between ICR and JIA patients. The oral health-related quality of life was significantly more negatively affected in the ICR group compared to the JIA group in the following domains: physical pain, psychological discomfort and psychological disability.
CONCLUSION: The present study illustrates more severe TMJ signs and symptoms, a greater degree of dentofacial deformity and negatively affected oral health-related quality of life in the ICR group when compared with the JIA group. The same degree of TMJ deformity was found in both groups. Our findings contribute valuable insights towards establishing diagnostic criteria for ICR patients and improving the differential diagnosis of JIA-related TMJ involvement.
