QoLquestionnaire based on modified family impact scale (FIS)before orthodontic treatment(T1) and after 6 months of the
start of treatment (T2). The Wilcoxon signed rank test was used to determine the significance difference in FIS scores
between T1 and T2. Effect size andminimal clinically important difference (MCID) for the FIS were also determined.
Results - There was statistically significant difference betweenFIS scores at T1 and T2 (P<0.001).
