No association between types of unilateral mandibular condylar abnormalities and facial asymmetry in orthopedic-treated patients with juvenile idiopathic arthritis

JIA patients with unilateral condylar abnormalities (deformation or erosion) exhibited significantly more severe dentofacial asymmetries than did the JIA patients without condylar abnormalities and the control subjects. We found the same degree of dentofacial asymmetry when dividing patients with condylar abnormalities into deformation and erosion groups.
