ABSTRACT

Objectives: This study aimed to determine the Missing Teeth (MT; mean number of missing permanent teeth) index experienced by year for adults between the ages of 19 and 64. Methods: This study was conducted by analyzing the raw data of participants in the 4th to 8th periods of the National Health and Nutrition Examination Survey (NHANES). For the statistical program, IBM SPSS / WIN 26 was used and an independent sample t-test was performed. Results: The average number of MT by year showed a decreasing trend. In 2007, 2008, 2010 and 2011, the average number of MT by sex was higher among females, and this was statistically significant (p<0.05). However, in 2019, males had a higher average number of MT than females, which was statistically significant (p<0.05). Conclusions: Males had a higher average number of MT than females in Korea, so it is considered that oral health programs or oral hygiene management according to sex are necessary.
