Objectives: This study aimed to develop a machine-learning model to predict the number of remaining teeth in the elderly and identify the most influential factors. Methods: Using the 9th wave of the Korean Longitudinal Study of Aging (KLoSA), 4,451 participants aged 65 and older were analyzed. Predictive models using XGBoost, Random Forest, and Logistic Regression were built based on demographic and health behavior variables. Results: XGBoost demonstrated the best performance (AUROC: 0.686, accuracy: 0.673, precision: 0.690, recall: 0.872, F1 score: 0.770). The top predictors were age, subjective health status, educational level, economic activity, and diabetes. Conclusions: The model has potential utility in identifying high-risk elderly populations and informing preventive oral health policies.
