| Outline of Final Research Achievements |
The opportunities of home dental care for elderly in need of nursing care and immunocompromised patients have been increasing. The improvement and establishment of the infection control for home dental care under differing environment with dental clinic are present urgent issues. The purpose of this study was to investigate the pollution status of the environments during home dental care and the habitat of oral pathogenic bacteria in the elderly in need of nursing care at home. This study revealed the spread of the community-acquired methicillin-resistant staphylococci in their oral cavities. It is necessary to pay attention to their future trends. The ATP measurement values used for the survey of environmental cleanliness showed the positive correlation with the number of bacteria in oral cavity, which could be led to the oral hygiene state evaluation.

| Academic Significance and Societal Importance of the Research Achievements |
唾液には院内感染病因細菌や新型コロナウイルスも多量に含まれ、歯科治療や口腔ケアの際には患者からエアロゾル飛沫の暴露リスクが非常に高い。歯科医院と比べ感染対策が十分でない在宅歯科医療実施環境における危険性についても言及したことは時宜を得て社会的意義がある。特に感染リスクの高い高齢者を対象とした口腔衛生管理の感染予防対策にも繋がるATP測定法はエビデンスに基づく１つの有力な指標として学術的意義がある。
