Objective of study is investigating the effect of low level laser on histomorphological changes in Achilles tendon in dogs. Twelve adult male dogs weighing 30 to 35 Kg (3-4 year old) were used for this study. Under general anesthesia and aseptic condition the dorsal surface of right Achilles tendon was exposed and after complete separation of connective tissue, it was splitted (striking 10 times) in full thickness in longitudinal fashion of 3cm in length in the mid-tendon area using BP blade no 15 in each one. These animals were divided into two groups of control (untreated) and experiment (treated with low level laser) having 6 animals each. The histomorphological changes was evaluated by using modified by collecting samples from mid splitted area of injured and normal tendons of each animal from treated and untreated. The results of this study indicated that additional exposure of tendon to low level laser as a local stimulator on severely injured or extensive lesion of Achilles tendon in dog will be highly useful in enhancing morphological changes in the treated tendon.
