Outline of Final Research Achievements

The purpose of this study was to examine the effects of the menstrual cycle on the oral environment of female athletes. As a result of investigating the oral environment of female athletes, caries experience and periodontal pocket conditions were good, but gingival inflammation and poor oral hygiene were observed. In addition, there was an experience that hindered competition due to intraoral troubles and a decline in occlusal ability. It was shown that awareness of the oral environment, such as prevention, is poor. No significant difference was observed between follicular and luteal phases. However, when examined individually, some athletes are at high risk of caries and periodontal disease, and it is necessary to improve interest in the oral cavity.

Academic Significance and Societal Importance of the Research Achievements

本研究により、女性アスリートの口腔内環境の状態や意識の低さが把握でき、パフォーマンスへの影響だけでなく、咀嚼能力の低下による栄養摂取への懸念も明らかになった。口腔内環境を整えることによる女性アスリートの体調管理方法を検討する上で一助となり得るが、月経周期の影響等について明らかになっていない点が多く、その解明が進むことが期待される。
