Outline of Final Research Achievements

The United States Food and Drug Administration has stipulated that the use of laser radiation from semiconductor and carbon dioxide gas lasers is effective for promoting wound healing after tooth extraction. However, there are almost no reports of basic research considered to have reached the status of evidence-based medicine. In this study, depending on the clinical procedure, we used each type of laser therapy after tooth extraction performed on rats, and then performed histopathological verification to determine the effects of this radiation on wound healing in the tooth extraction socket. Results show that formation of new bone and maturation of bone trabeculae were observed during the early stages of wound healing when either form of laser radiation was used after tooth extraction. We were also able to inhibit scar contraction of the extraction socket mucosa, minimize mucosal concavity, and maintain the height of the alveolar crest.
