Abstract
OBJECTIVES: The aim of the study was to evaluate the condylar and ramal asymmetry of the mandible in patients with juvenile idiopathic arthritis (JIA) using orthopantomographies (OPTs). METHODS: A total of 30 JIA patients with confirmed diagnosis of JIA and a routine OPT, seeking for orthodontic therapy, free of specific symptoms of temporomandibular joint involvement, and 30 normal matched subjects with OPT were comprised in the study. The method of Habets et al. was used to compare the condyles and rami in OPT. The significance of between-group differences were assessed using Mann-Whitney test. RESULTS: The results showed a high significant difference in the range of asymmetry of the condyle, being the patient group highly asymmetrical (P < 0.0001). No differences were found in the range of asymmetry of the ramus between groups (P = 0.47). The intra-group comparison between males and females showed a difference in the patient group (P = 0.04), being the females more asymmetric. CONCLUSIONS: Knowing that the temporomandibular joint (TMJ) is highly susceptible to inflammatory alterations during growth, even in absence of symptomatology, and being the OPT a cost-benefit favorable imaging tool widespread in the dental field, the latter could be used as a first screening examination in JIA patients to calculate the condylar asymmetry index. The use of this screening tool will help the physicians in addressing the patients that should undergo a more detailed TMJ imaging to early detect TMJ abnormalities and to early set up a targeted therapy of the related cranial growth alterations.
