This study uses the 9th 1st year (2022) National Health and Nutrition Examination Survey to analyze the relationship between sleep time and the number of existing teeth for the adult population aged 19 or older to provide basic data on related dental development. There is a purpose. This program is designed to improve sleep quality and maintain the number of viable teeth in the future. The subjects were 53,220 people who answered the questions. The collected data were analyzed using SPSS (ver 21.0) program using complex samples, and chi-square analysis and logistic return analysis were performed. As a result, it was found that 2.537 times more existing teeth remained when sleep time was 9 hours or more than when sleep time was 6 hours or less, and there was a statistically significant difference. In conclusion, it is necessary to recognize the importance of the number of remaining teeth and to make efforts to manage personal immunity, such as sleep management for adults, and to promote and prevent oral care and oral health education in order to maintain the number of remaining teeth.
