Abstract

OBJECTIVES
The purpose of this study was to compare scaling rates in 16 cities and provinces using data from the Community Health Survey (CHS) and National Health Insurance Service (NHIS).
METHODS
This study involved cross-sectional secondary data analysis. A total of 16,646,190 subjects who participated in the CHS and 218,184 subjects in the NHIS were included in the final analysis. The dependent variable was the scaling rate, and the independent variables were sex, age, and 16 regions. The study included individuals aged 19 years or older who received scaling between August 2014 and August 2015 in the past year in the CHS and codes U2232 (scaling) and U2233 (scaling before periodontal treatment) in the NHIS. The total scaling rates were compared between the CHS and NHIS. The differences in scaling rates according to sex, age, and 16 regions were analyzed.
RESULTS
The CHS (42.6%) scaling rates were 17.5% higher than the NHIS (25.1%) scaling rates in 16 regions in 2015. The median in the CHS data was in Busan (41.5%), while that in the NHIS data was in Jeonbuk (23.5%). There was no significant difference between scaling rates above and below the median region in the CHS and NHIS.
CONCLUSIONS
The results suggested that CHS data, which show a higher rate, should be used to assess and monitor the dental needs of community residents. NHIS data should be used to evaluate community oral health projects. It is necessary to develop health indicators for the community oral health project of input, process, and outcome evaluation.
