The effect of Er:YAG laser irradiation on the bone tissue.

Caption

Laser irradiation causes photomechanical response, photobiological activation reaction, and photochemical response in the various tissues and cells. Downregulation of Sost expression in the bone tissue was observed after Er:YAG laser bone ablation. Because sclerostin (coded by Sost) suppressed bone formation by inhibiting canonical Wnt signaling pathway, there is a possibility that Er:YAG laser irradiation to the bone enhances bone formation.
