Abstract:
Objectives:This study aimed to evaluate the relationship between oxidative balance score (OBS), a metric indicating an individual’s oxidative balance status, and the number of teeth in a sample of Korean adults.
Methods:This cross-sectional study included 13,199 adults aged 19 and older who participated in a health survey and oral examination. Subsequent to the adjustment for confounding factors, a logistic regression analysis was employed to evaluate the probability of a subject belonging to a number of teeth category based on OBS level.
Results:In the group with OBS level T2, the likelihood of having NT1 (0–10 teeth) was found to be significant adjusted for all variables (odds ratios: 1.51, 95% confidence intervals: 1.195–1.908). In the multinomial model, a significant association was observed for the NT1 category, whereas no significant association was found for the NT2 (11–20 teeth) category after adjustment.
Conclusion:In the group with OBS level T2, the likelihood of having NT1 (0–10 teeth) was found to be significant. As this study examines cross-sectional associations, the necessity of conducting longitudinal research as subsequent studies is evident to ascertain the existence of causality.
