Compare the effect red and green low level laser light accelerates the healing of the incision in the skin after the suturing in hamsters

Accelerated wound healing was the first application for this type of laser. In terms of green light laser ability which whether it can enhance wound healing or not there is some disagreement. this study was done in order to compare the green and red light lasers (less powered one) in terms of accelerated wound healing which can be done surgically on the skin. In this study thirty healthy, mature hamster from suyrian strain was selected and randomly divided into three different group as below: A: control group, B: group which was under the radiation of low level red laser, C: group which was under the radiation of low level green laser. After the induction of general anesthesia, the straight incision at the length of two cm was created in the dorsal zone of animal, then by means of nylon 5-0 was sutured in a simple manner. In the group A the cutted site without any intervention was remained intact in order to proceed first type of wound healing, in the group B (by red laser) and C (by means of green laser) the cutted site was treated with the velocity of 0.5 J/cm 2 during one minute by constant movement of lasers on the surface of incision which was continued up to six days. Sampling was done in the 3th 7th, and 12th days. The average wound healing in groups B and C were significantly higher than the control group, but between the two green and red laser, there was no meaningful difference. Although the red laser a little bit was good during operation compared with the green one. Less powered laser accelerates the process of wound healing. In those situations which the case is resistance to wound healing we can use less powered lasers.
