Abstract :

Accelerated wound healing was the first application for this type of laser. In terms of green lightlaser ability which whether it can enhance wound healing or not there is some disagreement. thisstudy was done in order to compare the green and red light lasers (less powered one) in terms ofaccelerated 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 groupas 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 generalanesthesia, 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 sitewithout any intervention was remained intact in order to proceed first type of wound healing, inthe group B (by red laser) and C (by means of green laser) the cutted site was treated with thevelocity of 0.5 J/cm2 during one minute by constant movement of lasers on the surface of incisionwhich was continued up to six days. Sampling was done in the 3th 7th, and 12th days. Theaverage wound healing in groups B and C were significantly higher than the control group, butbetween the two green and red laser, there was no meaningful difference. Although the red lasera little bit was good during operation compared with the green one. Less powered laseraccelerates the process of wound healing. In those situations which the case is resistance towound healing we can use less powered lasers.
