| Outline of Final Research Achievements |
In this study, SRP using a hand scaler or Er:YAG laser was performed on 52 patients with moderate to severe generalized chronic periodontitis, and the bacteremia that occurred during SRP and the accompanying biological response were evaluated. analyses, and the effectiveness of Er:YAG laser on these changes. As a result, both groups showed significant improvement in clinical parameters including periodontal pocket depth. In addition, a tendency for body temperature to rise after SRP was observed in both groups, and in terms of serum biomarkers, a tendency for cortisol to rise was observed in the hand scaler group. From the above, it was suggested that SRP using Er:YAG laser is less invasive to the body and improves clinical parameters to the same extent as hand scalers.

| Academic Significance and Societal Importance of the Research Achievements |
超高齢社会における歯周治療のニーズとして、より低侵襲であることが挙げられるが、それに対する方法として、Er:YAGレーザーの有効性を示すことができた。また、本研究によってSRPが全身状態へ及ぼす影響が明らかになった。臨床・公衆衛生的な歯科的介入を考えた際に、本研究の社会的意義は大きいと考える。
