Objectives: The purpose of this study was to assess the applicability of the Significant Tooth Lossindex as a new statistical indicator and to analyze the socio-economic factors of the participantsincluded 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 Losswas 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 testand logistic regression analysis were used to analyze the socio-economic factors of the SignificantTooth 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 Losswas 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 householdincome 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.
