  1. Uni-Aff affected side—unilateral JIA, Uni-UnAff unaffected side—unilateral JIA, Bil-Aff bilateral JIA, Ctrl control group
  2. *p value < 0.05 was considered as statistically significant
  3. AValues are means ± standard deviations of each patient average value between right hemimandible and left hemimandible
  4. BValues are means ± standard deviations of each patient average value between unilateral affected side and unilateral unaffected side
