Incidence of orofacial manifestations of juvenile idiopathic arthritis from diagnosis to adult care transition: a population-based cohort study.

Orofacial signs and symptoms were frequent findings in children and adolescents with JIA. TMJ involvement was seen in 30.1% of the cohort; and 20.6% of the total cohort developed JIA-related dentofacial deformity before transition into adult care. This is the first population-based study in the biologic era to document these frequent orofacial complications in children with JIA.
