“…The DMF rate, DMFT index, and Cr index is higher in women than in men. This finding is the same as that of Jung et al, who reported that female students were at higher risk of experiencing tooth decay than male students [43]. This is because women are exposed to the risk of dental caries more than men as they are more likely to develop permanent teeth, including the first molars, earlier than men [44].…”

Background: In South Korea, dental sealant was included in the National Health Insurance Services (NHIS) coverage for the first molar for ages 6-14 in December 2009. The second molar was included in 2012, and the age of insurance coverage was extended to under 18 in 2013. This study aimed to verify the effectiveness of an NHIS dental sealant coverage policy for children and adolescents by comparing the changes in first molar oral health indicators before and after policy implementation. Methods: The Korea National Health and Nutrition Examination Survey data were analyzed; the fourth period (2007-2009) provided data for before and the sixth period (2013-2015) provided data for after policy implementation. The proportion of individuals with first-molar sealant, decay-missing-filled first molar permanent teeth, and single crowns in the group aged 11-20 years were calculated. Data were analyzed using chi-square for complex samples and the complex samples general linear model. In addition, complex-sample logistic regression analysis was performed to confirm the association between factors. Results: Compared with non-beneficiaries, among policy beneficiaries, sealant ownership increased by 7.7% (from 27.8 to 35.5, P < 0.001), and the number of permanent teeth with sealant per capita increased by approximately 0.4 to 0.8 (P < 0.001). The proportion of individuals with decay-missing-filled permanent teeth decreased by 9.1% (from 68.4 to 59.3, P < 0.001), and the average decay-missing-filled permanent teeth index per person decreased by approximately 2.0 to 1.5 (P < 0.001). The rate of single-crown holders decreased by 2.7% (from 8.7 to 6.0, P > 0.05), and the average single-crown index decreased by approximately 0.11 to 0.08 per person(P > 0.05). The number of sealants increased with age and household income (P < 0.001). The mother's education level affected sealant experience (P < 0.05). The caries rate was higher in females and older respondents (P < 0.001).

Results: Compared with non-beneficiaries, among policy beneficiaries, sealant ownership increased by 7.7% (from 27.8 to 35.5, P<0.001), and the number of permanent teeth with sealant per capita increased by approximately 0.4 to 0.8(P<0.001). the proportion of individuals with decay-missing-filled permanent teeth decreased by 9.1% (from 68.4 to 59.3, P <0.001), and the average decay-missing-filled permanent teeth index per person decreased by approximately 2.0 to 1.5( P <0.001). the rate of single-crown holders decreased by 2.7% (from 8.7 to 6.0, P >0.05), and the average single-crown index decreased by approximately 0.11 to 0.08 per person( P >0.05). The number of sealants increased with age and household income ( P <0.001). The mother’s education level affected sealant experience ( P <0.05). The caries rate was higher in females and older respondents ( P <0.001). Conclusions: The sealant covered by NHIS contributed to decreasing dental caries in Korea. However, policies that can reduce oral health inequality should also be considered, and a follow-up study is required for long-term sealant maintenance in Korea.

“…More attention should be given to the fact that coverage of light-curing composite-resin restoration by National Health Insurance in 2018 could influence the number of filled teeth. Jung et al [ 19 ] showed that a significant proportion of the sub-group used to calculate the SiC index had no sealed fissures on the first molar and lived in rural areas. The public oral health programme to provide fissure sealant by the government budget could be reinforced to reduce the gaps between rural and urban areas.…”

“…Kim and Jeon [ 16 ] showed that the DMFT values in 12-year-olds had declined and that general oral health had improved but that its inequality had increased. Several studies using cross-sectional or other designs have reported data related to Korean children’s oral health using DMFT values [ 17 , 18 ] and the SiC index [ 19 ] to express the inequality of oral health [ 16 ]. In this study, we used a simple index based on the number of DMFT, the SiC index, and the SiC index/DMFT ratio to express disparities in the incidence of dental caries.…”

BackgroundThe aim of this study was to analyse the prevalence and severity of dental caries among Korean children aged 8 and 12 years over a period of 12 years by determining the number of decayed, missing, and filled teeth (DMFT) and the Significant Caries index (SiC index).MethodsStratified cluster-sampled data from the National Oral Health Survey conducted from 2000 to 2012 were analysed. In 2000, 2006, and 2012, a total of 2397, 2650, and 9601 children aged 8 and 12 years were examined, respectively. The children’s oral health status, including the number of DMFT and fissures sealed teeth, was examined and recorded. The SiC index was calculated according to the child’s residential district.ResultsOver the 12-year period, the percentages of caries-free children aged 8 and 12 years increased from 26.0 to 42.7 % and from 53.4 to 69.6 %, respectively. The percentages of children aged 8 and 12 years with sealed teeth in 2012 were 62.1 and 62.5 %, respectively, more than triple the rates in 2000. The mean DMFT values of children aged 8 and 12 years decreased from1.04 to 0.67 and from 2.86 to 1.84, respectively. The SiC index of children aged 8 and 12 years also decreased from 2.73 to 1.97 and from 6.13 to 4.51, respectively. The rate of reduction in DMFT among 8- and 12-year-old children in the second 6 years of the observation period was lower than that in the first 6 years.ConclusionsA remarkable decline in dental caries of 8- and 12-year-old Korean children was observed over the 12-year study period. The mean DMFT values and SiC index of children aged 8 and 12 years decreased. The reduction rate between 2000 and 2006 was higher than that between 2006 and 2012.
