Outline of Final Research Achievements |
Although there is continued progress in the analysis of the main bacterial components that make up periodontal pocket plaque, most bacterial components have not been analyzed until now. Therefore, the purpose of this research is to use next-generation sequencers (NGS) to investigate the bacteria involved in periodontal disease which have previously been difficult to analyze. The target population is adults with advanced periodontal disease and those with advanced periodontal disease due to Down syndrome. This study will reveal the previously unexplored bacterial composition of plaque in patients with Down syndrome

Academic Significance and Societal Importance of the Research Achievements |
免疫機能の低下を伴うダウン症候群患者を対象として,歯周病の評価とNGSによる解析結果との関係を調べた本研究ではNGSを用いたショットガンメタゲノム(SGM)とメタ16S解析により,従来解析の対象とすることが困難であった細菌を含めて,プラークを解析することが可能となった。Campylobacterales目はプラーク中に占める割合は最大6.1%と多くはなかったが,ダウン症候群患者で比較的高い割合で存在していた。本研究により,NGS解析では16S rRNA解析よりも精度よく細菌叢の構成を調べることができた。
