Table 2.
The number of existing teeth and binary status based on the median number of existing teeth by age group.
| Age Group (Years) | Participants | Number of Existing Teeth | Number of Participants | ||
|---|---|---|---|---|---|
| Mean (SE) | Median | ≤Median | >Median | ||
| Total | 3255 | 21.31 (8.41) | 24.00 | 1750 | 1636 |
| 55–59 | 855 | 25.23 (5.43) | 27.00 | 497 | 358 |
| 60–64 | 747 | 23.00 (7.16) | 25.00 | 380 | 367 |
| 65–69 | 692 | 21.24 (7.95) | 24.00 | 330 | 362 |
| 70–74 | 562 | 18.87 (8.71) | 21.00 | 285 | 277 |
| 75–79 | 399 | 16.33 (9.57) | 18.00 | 198 | 201 |
Note. In KNHANES-Ⅵ (2013–2015), the ages of all 80+ year-old participants were recorded as 80 years instead of the actual ages, which was different from the approach used in previous surveys. Therefore, only the data from 3255 participants aged 55–79 years were used in the analysis of the variables related to the number of existing teeth.
