Abstract
Dental sealant is a procedure to prevent dental caries on the occlusal surface of healthy teeth. Raw data from the 6th-7th Korean National Health and Nutritional Examination Survey (KNHANES) were analyzed. This study was conducted to provide basic data which is necessary for the national health care project and for expanding the standards of coverage for the Dental sealant procedure. In this study, subjects were a total of 4,366 children from the age of 6 to 18 and surveyed for the Amount of Received Dental sealant and rate of Received Dental sealant. In 2012, the coverage rate for pit and fissure sealing procedures differed significantly in terms of age, residential area and average monthly income. This coverage varied as per average monthly income in 2014 and as per age and average monthly income in 2017 (P < 0.05). In 2014, average monthly income had a significant influence on the coverage rate, while age and average monthly income had a significant influence on it in 2017 (P < 0.05). These findings suggest that in order to increase the sealing procedure coverage, continuous promotion of dental sealant projects, reduction of copayments, inclusion of varied tooth types and age groups, expansion of coverage to isolated areas and inclusion of socially disadvantaged groups are necessary.
