Real-world evidence of the impact of obesity on residual teeth in the Japanese population: A cross-sectional study
Fig 4
Percentage of obesity/ non-obesity/ smoking/ non-smoking subjects with residual teeth at each position by age groups (30s-60s).
Percentage of subjects with residual teeth was calculated as the proportion of subjects that have a residual tooth at the particular position. The percentage of subjects with residual teeth was compared among the 4 groups in the same age group, and positions with a significantly lower percentage of subjects having a residual tooth than the expected value are shown in black (p <0.05). OB-; non-obesity, OB+; obesity SM-; non-smoking, SM+; smoking.
