The purpose of this study was to grasp the benefits from pit and fissure sealants and to analyze the factors of influencing the benefit amount by using the raw data of the Korea National Health and Nutrition Examination Survey for 2007~2013 targeting the subjects aged from 6 years in full to 18 years. The analysis was used STATA 11.0. As a result of the analysis, the following conclusions were obtained. It rose up to 1.24 pieces after carrying out the national health insurance coverage from averagely 0.93 piece until the year in 2007~2009 (up to November) when is before enforcing the national health insurance coverage in the pit and fissure sealants. The benefits from pit and fissure sealants depending on general characteristics were surveyed to be higher in the higher income level, in the more subscription to health insurance and private insurance, and in the more toothbrushing frequency per day. The factors that have influence upon the benefits from pit and fissure sealants were shown to include whether or not to have the national health insurance coverage in the pit and fissure sealants, income level, health insurance type and private insurance subscription appearance, and one-day toothbrushing frequency. Synthesizing the results, a rise in the benefits from pit and fissure sealants is shown in 2010 based on December 2009 when the national health insurance coverage in the pit and fissure sealants was implemented, but is showing the tendency of declining again from 2011. To increase the benefits from pit and fissure sealants, it is thought that the schemes will need to be discussed such as reinforcing publicity on the national health insurance coverage in the pit and fissure sealants, expanding a support for low-income bracket, and differentiating the outpatient cost sharing according to socio-economic level.

Pit and fissure sealants has been proven as safe and effective method of caries prevention. But improper application of pit and fissure sealant may masking the caries process in occlusal fissure. Dentists have to understand the correct and exact application method of pit and fissure sealant for he good result of caries prevention. A key factor to enhanced the effectiveness of caries prevention is retention of pit and fissure sealant. Deep penetration of material into fissure and least marginal leakage around the fissure orifice are the major concerns for dentists to achieve the successive application of pit and fissure sealants. This paper reviewed the literature on the pit and fissure sealants under the following subtitles for enhanced retention : (1) application timing, (2) Indication, (3) Occlusal prophylaxis, (4) Materials, (5) Penetration, (5) Recall check Dental profession must perform the exact application of pit and fissure sealant because this procedure is one of the most technique-sensitive one in dental field.

Background: This study aimed to explore the overall perception of pit and fissure sealants and suggest methods to revitalize their current stagnation. Methods: To determine the social perception of the change in coverage policy for pit and fissure sealants, we categorized them into five time periods. The first period (December 1, 2009 to November 30, 2010), the second period (December 1, 2010 to September 30, 2012), the third period (October 1, 2012 to May 5, 2013), the fourth period (May 6, 2013 to September 30, 2017), and the fifth period (October 1, 2017 to December 31, 2022). We utilized text mining, an unstructured big data analysis method. Keywords were collected and analyzed using Textom, and the frequency analysis of the top 30 keywords, structural features of the semantic network, centrality analysis, QAP correlation analysis, and co-occurrence analysis were conducted. Results: The frequency analysis showed that the top keywords for each time period were 'Cavities', 'Treatment', and 'Children'. In the structural features of the semantic network of pit and fissure sealants by time period, the density index was found to be around 1.00 for all time periods. The QAP correlation analysis showed the highest correlation between the first and second periods and the fourth and fifth periods with a correlation coefficient of 0.834. The co-occurrence analysis showed that 'cavities' and 'prevention were the top two words across all time periods. Conclusion: This study showed that pit and fissure sealants are well accepted by the society as a preventive treatment for caries. However, the awareness of health education related to these sealants was found to be low. Efforts to revitalize stagnant pit and fissure sealants need to be strengthened with effective education.

The purpose of this study is to compare microleakage and penetration depths of sealants applied in carious and sound fissures. Extracted premolars(n=80) were divided into 4 groups according to caries status. 1; sound, 2; stained, 3; initial caries, 4; enamel caries. Sealants were applied to the occlusal groove as per manufacturers' instructions, and specimens were thermocycled, stained, sectioned, and examined for microleakage and penetration ability. The results of the present study are as follow: 1. It showed significantly higher microleakage scores in group I than group Two, Three, Four(p<0.05), but no significant difference was found between group Two, Three, and IV(p>0.05). 2. It showed significantly higher penetration scores in group Four (p<0.05), followed by group One, Two, Three, but no significant difference was found between group One, Two, and Three(p>0.05). Based on the results of present study, when the borders of the fissure sealant are on carious enamel, a significantly higher microleakage must be expected. It is considered that depth of enamel caries in the fissure should be taken into account when applying a fissure sealant.
