Irradiation effect of low-energy laser on alveolar bone after tooth extraction. Experimental study in rats.
A histopathological study of the initial healing of extraction wounds following low-energy laser irradiation, using a gallium-arsenide semi-conductor laser, was carried out in rats. The results suggest that this mode of treatment has a beneficial effect on initial bony wound healing. It was found that proliferation of fibroblasts was more prominent in the irradiated group, and so was the formation of trabecular osteoid tissue. The deposition of lead in the newly formed bone suggests a more rapid ossification in the irradiated group.
