Outline of Final Research Achievements

In oral health promotion, it is important to understand health disparities, including health behaviors (e.g., food choice and eating behavior), quality of care and genetics, across all stages. This study aimed to conduct oral health survey in Kyushu to clarify the actual situation of young adult and investigate their oral health behavior s and genetics in this regard.
Younger people had shown poorer the dental health than older people. It was suggested that “the time required for tooth cleaning” and “habitual Intake of Vitamins” influence oral environment. It is necessary to hold further discussions on the characterizing genetic influence on oral environment.

Academic Significance and Societal Importance of the Research Achievements

若年成人層における歯科口腔保健の取組として、歯や歯茎の健康に対する戦略方向性が示唆された。また、今後の取組課題である、因子特性による口腔機能格差問題においても、個人差を基に実施する“テーラーメイド歯科口腔保健”の仕組みづくりへ応用するための基礎研究となることが期待される。
