Table 3 Evaluation of OPTs of 46 patients: Quotient of right and left condylus-height in %; quotient of right and left ramus-height in %; quotient of right and left mandible-height in %; Also evalutation of asymmetry indices SI1 and SI2 according to Kjellberg et al. [30]
From: TMJ pathomorphology in patients with JIA-radiographic parameters for early diagnosis-
