Abstract:
Objective To quantify the effect of 650 nm semiconductor laser irradiation on cutaneous wound healing in rabbits. Methods Model wounds were induced in 21 adult male rabbits. They were then divided randomly into a control group, a 5 mW irradiation group and a 10 mW irradiation group. Biometry and light microscopy were used to investigate the effect of low intensity laser therapy (LILT) on cutaneous wound healing. Results Statistically significant differences were observed among the groups in terms of wound shrinkage. The differences between the irradiated and control groups were significant at the 5th, 9th and 13th day. However, any differences between the S mW and 10 mW groups were not significant. Conclusions LILT at 650 nm at either 5 mW or 10 mW and 1 J/cm2 accelerates cutaneous wound healing in rabbits. But irradiation at 10 mW is no more effective than at 5 mW.
