Outline of Final Research Achievements

In vitro, it was revealed that the cell proliferation ability and the substrate metabolism ability were enhanced as a result of irradiating the mouse calvaria-derived osteoblast cell (MC3T3-E1) with a cold laser.In addition, when the effect of cold laser on intracellular messenger was examined, it was suggested that it affects MAPK/MEK signaling pathway.
In vivo, an experimental rat tooth movement model was created to compare the tooth movement distance during laser irradiation. As a result, it was suggested that tooth movement during laser irradiation was enhanced.

Academic Significance and Societal Importance of the Research Achievements

本研究では、コールドレーザーの被照射組織に対する生体活性作用(バイオスティミレーション効果)と、その高い安全性に着目した。コールドレーザーは従来の低出力半導体レーザーと比較して高い光エネルギーを持ちながら、超短パルスレーザーであるため、照射時の組織の熱損傷を伴わないという特徴がある。そのため、照射時にはより安全にレーザー光を深部組織に到達させることが可能となる。
本研究結果から、矯正歯科治療時においてコールドレーザー照射を行うことにより、歯の移動を効率化することができる可能性が示唆された。
