Abstract

OBJECTIVES: The purpose
of this study was to review the relationship between pit and fissure sealant (PFS) experience and the socio-economic factors of adolescents before and after coverage by National Health Insurance (NHI).
METHODS
Our sources were the Korea Youth Risk Behavior Web-based Surveys from 2008 and 2014. The variables used were PFS experience, demographic factors, socio-economic factors, and oral health-related behaviors.
RESULTS
PFS experience was higher in 2014 than in 2008. The relationship between PFS experience and socio-economic factors was significant in both 2008 and 2014. Although the inequity of PFS experience among adolescents was reduced as PFS was included in NHI coverage, a disparity still exists.
CONCLUSIONS
Even after NHI coverage included PFS, the policies to reduce the inequity of PFS experiences among adolescents should be further devised. In addition, a longitudinal study is recommended to determine the relationship between PFS experience and various socio-economic or behavioral factors.
