摘要：

The purpose of this study was to examine histologically the healing process of the bone defect created by Er:YAG laser irradiation in the long-term, in comparison with that created by conventional rotating bur. Two straight groove-like defects were prepared on the rat calvaria by Er:YAG laser or rotating bur. After operation, SEM analysis of the lased surface and histological observation of the healing process were performed. The results showed that the Er:YAG laser was capable of ablating bone tissue with the same effectiveness as the bur treatment, without causing severe thermal damage. The bone defect created by Er:YAG laser irradiation was repaired by new bone uneventfully within 2 months, almost equal to that of the bur treatment. These results suggest that the Er:YAG laser can be clinically applicable to periodontal bone surgery. (C) 2002 Elsevier Science B.V. All rights reserved.
