[RESULTS] A statistically significant amelioration in mean mouth opening ability was observed in the KT group ( T1-BL : -0.08 cm 0.49 ( p = 0.025 ) ; T2-BL : 0.07 cm 0.59 ( p = 0.012 ) ; T3-BL : 0.20 0.63 ( p = 0.013 ) ; T4-BL : 0.42 0.59 ( p = 0.003 ) ) compared to the no-KT group ( T1-BL : -0.47 cm 0.86 ; T2-BL : -0.39 cm 0.84 ; T3-BL : -0.24 0.89 ; T4-BL : -0.13 1.02 ) .
