Abstract
Aim of study: To evaluate the effect of different wave length of low level laser therapy on the degree of inflammation following soft tissue injury.
Materials & Methods: Nine healthy rabbits aged (6-10) months ,weights 1-1.5 Kg were introduced to surgical operation by incision of 2cm of skin and subcutaneous tissue on the dorsum of rabbit ,the animals were divided into three groups .The first group(control) applied the same surgical procedure but without laser irradiation ,the second group irradiated by 650nm,the third group irradiated by 810nm,the exposure time was(1mint) at 2.5 mw immediately after surgery and then at day 2,3,5,7 post operative days .The experimental animals were scarified at the subsequent postoperative days and the specimens were examined histopatholgically. Number .of inflammatory cells were calculated statistically to assess the degree of inflammatory response.
Results: The animals irradiated with 650nm of laser were significantly differences in all post operative days compare to control but non significant differences in the group treated with 810nm of laser except in 7 postoperative days compare to control .Statistically comparison of both treated groups(650,810nm) showed significant differences in all post operative days.
Conclusion: laser reduce the inflammation and enhance the healing by increase the inflammatory cells at wave length of 650nm but induced damage (reduction of healing)at 810nm.
Keywords: different wave length ,laser ,soft tissue healing.
