Abstract

Objectives
The purpose of this study was to assess the applicability of the Significant Tooth Loss index as a new statistical indicator and to analyze the socio-economic factors of the participants included in the Significant Tooth Loss.
Methods
This study used raw data from the Korea National Health and Nutrition Examination Survey (2016-2018). The survey included 13,199 adults aged ≥19 years. The Significant Tooth Loss was defined as a group with more than a third quartile (top 1/4) of the total number of tooth loss. The Significant Tooth Loss index was defined as the mean tooth loss in the group. Chi-square test and logistic regression analysis were used to analyze the socio-economic factors of the Significant Tooth Loss, and absolute and relative differences were calculated to confirm oral health inequality.
Results
Among overall tooth loss in adults, the proportion of tooth loss in the Significant Tooth Loss was 83.8%. The Significant Tooth Loss index was a useful indicator to determine oral health statistics. Socio-economic factors that were associated with significant tooth loss were age, gender, region, household income, and education. Oral health inequality was observed based on household income and education.
Conclusions
The Significant Tooth Loss index should be used to measure the level of oral health. Measures to reduce tooth loss should be investigated.
