The results of this study were the average healing time in the control group was 5.28 ± 0.958 with a Min-Max 3-6 days, while in the intervention group the average healing time was 3.00 ± 1.372 with a Min-Max 2 -5. There was a significant difference (p-value = 0.001) in the length of days of healing between the control and intervention groups.
