Abstract Purpose Juvenile idiopathic arthritis (JIA) is an autoimmune disease with multiple potential causal factors. In case of temporomandibular joint (TMJ) affection, the inflammatory reaction can result in restricted mandibular growth with implied skeletal and facial deformities. Aim of the present study was to examine dentoalveolar and occlusion characteristics in children with JIA. Patients and methods The sample consisted of 66 children (27 boys, 39 girls) with JIA. Thirty-three of them showed unilateral or bilateral condylar destruction, while the other half did not manifest any TMJ involvement. Corresponding dental casts of these patients were evaluated and Angle classification, overjet, overbite, crossbite, crowding, and ectopic teeth were registered. All dental casts were subsequently scanned and digitized to analyze 26 additional variables. Subgroups according to sex and condylar affection were formed. Statistical analysis was performed using Fisher’s least significant difference (LSD) post hoc test of analysis of variance (ANOVA). Results The prevalence of Class II, division 1 malocclusion in this JIA sample was high (28.8%). Compared to girls, boys had significantly greater dental arch widths and lengths. The group with bilateral condylar affection had significantly decreased lower arch length and increased irregularity index (p < 0.035) compared to the non-affected group. Conclusions Bilateral condylar involvement in children with JIA seems to reduce the lower arch length, while increasing the irregularity index of the lower front teeth.

Dentoalveloäre Merkmale bei Kindern mit juveniler idiopathischer Arthritis Zusammenfassung Zielsetzung Die juvenile idiopathische Arthritis (JIA) ist eine Autoimmunerkrankung mit zahlreichen ätiologischen Faktoren. Bei Beteiligung des Kiefergelenks (TMJ) kann die entzündliche Reaktion das Wachstum des Oberkiefers einschränken und zu skelettalen und fazialen Deformierungen führen. Ziel der vorliegenden Studie war es, bei Kindern mit JIA dentoalveoläre Merkmale und mögliche Auffälligkeiten in Hinblick auf die Okklusion zu untersuchen.
