Abstract

Objectives
The purpose of this study was to identify factors related to severe tooth loss among sociodemographic, oral health behavior, and systemic disease factors.
Methods
This study used raw data from the Korea National Health and Nutrition Examination Survey (2016-2018), which included 13,199 adults aged ≥19 years. The severe tooth loss was defined as a group with more than a third quartile (top 1/4) of the total number of tooth loss. Logistic regression analysis was used to evaluate the correlations.
Results
Sociodemographic factors had a were more factors significantly correlated on severe tooth loss than oral health behavior-related and systemic disease-related factors. Among the assessed sociodemographic factors, age, resident area, household income, education level, and household type were correlated with severe tooth loss, with education level having the greatest impact. Among the oral health behavior-related factors, smoking had the greatest impact on severe tooth loss; tooth brushing frequency was also an important factor. Among the systemic disease-related factors, only diabetes incidence was associated with severe tooth loss.
Conclusions
Promoting smoking cessation, proper tooth brushing, and diabetes management could reduce severe tooth loss. Moreover, sociodemographic factors should be taken into account while planning oral health promotion projects.
