Abstract:

Objective: The effect of infrared light of gallium aluminum arsenide (Ga-Al-As) lasers on wound healing of hard palate gingival was comparedwith control group. Background data: Low level laser therapy (LLLT) has been used to accelerate the wound healing, but a lot of questions about the use of it as a therapeutic agent have not been answered yet. Methods: Seventy five adult male mice after surgical procedure were divided into 5 groups (n=15): Control group: without laser, GD1 and GD2 groups: treated with Ga-Al-As laser (wavelengths 830 nm, peak power 25 mW, and spot size 0.10 cm?). Five animals from each group were sacrificed by inhalation of chloroform in closed space on the third, seventh and fourteenth days after surgery, and samples were removed for histological analysis. Results: On the third and seventh day post surgical procedure the number of PMN in all experimental groups was significantly lower than that from control group. On the seventh and fourteenth, the fibroblasts and endothelial cell counts in all experimental groups were also significantly higher than that from control groups, and the number of fibroblast on seventh and fourteenth days was the only significant difference between experimental groups.
