Dentoalveolar characteristics in children with juvenile idiopathic arthritis
Abstract
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. 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). 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 signif...Continue Reading

Autoimmune Diseases
Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
