Bone regeneration after different lengths of exposure to laser irradiation. [Rabbits]

Journal Article:

Abstract

Rabbits in which a portion of the tibia was excised and replaced with preserved bone were locally irradiated by an LG-75 laser (25 mv) for 30 seconds, 1, 2, 5, and 10 minutes a day for a month. Histological examination of sections showed an acceleration of the inflammatory reaction and more rapid maturation of periosteal callus in experimental animals compared to controls. Cartilage appeared on day 9 instead of 15. The proliferation of histiogenic cells and their differentiation into fibroblasts and osteoblasts were more vigorous than in the control. The effects of irradiation on osteosynthesis were directly dependent on the duration of exposure. The development of the inflammatory reaction and resorption of the graft were most pronounced in the animals exposed for 10 minutes daily.
