Proportional changes in lesion percentage (PL%) overtime relative to T0 across the treatment groups

Evaluation times	Group
	Control	PRF	PRF/ACS
T0/T0	1cd	1 bc	1 ab
T7/T0	1.3 ± 0.03 b	0.95 ± 0.02 cd*	0.99 ± 0.016 a*
T14/T0	1.3 ± 0.02 b	1.12 ± 0.04 b*	0.92 ± 0.019 b*#
T30/T0	1.4 ± 0.02 a	1.31 ± 0.04 a	0.78 ± 0.02 c*#
T60/T0	1.1 ± 0.03 c	1.02 ± 0.04 bc	0.81 ± 0.019 c*#
T90/T0	1.0 ± 0.02 d	0.87 ± 0.01 d*	0 d*#
T150/T0	0.65 ± 0.02 e	0 e*	0 d*

Times with different superscript letters ( a, b, c, d, e ) are significantly different at p < 0.05

^* there is a significant difference compared to the control group in the same time at p < 0.05

^# there is a significant difference compared to the PRF group in the same time at p < 0.05
