Objectives: The purpose of this study was to investigate parents' recognition and attitudes toward national health insurance coverage of sealant by the dental hygienists. Methods: A self-reported questionnaire was filled out by 329 elementary school children parents in G metropolitan city and N city from July 11 to 27, 2015. The questionnaire consisted of general characteristics of the subjects, recognition and attitudes toward national health insurance coverage of sealant and sealant by the dental hygienist, and recognition toward national health insurance. The data were analyzed by a descriptive analyses, multiple regression and logistic regression analysis using SPSS 12.0 program. Results: Recognition of national health insurance coverage was 2.52 times higher in high school and 4.97 times higher in recognition toward purpose of sealant. Factor affecting recognition of national health insurance was subscription of private health insurance, recognition of sealant treatment by dental hygienist (DH) and recognition of national health insurance coverage of sealant. Attitude toward sealant treatment by DH was positive in experience of sealant, recognition of sealant treatment by DH and experience of sealant treatment by DH. Factor affecting satisfaction on the sealant by DH was recognition of sealant treatment by DH and recognition of purpose of sealant. Conclusions: To increase national health insurance coverage of sealant, it is necessary to expand positive public relations of sealant by the dental hygienist.

Background: Dental caries prevention is a key research focus in dentistry, requiring advancements in the formulation of dental sealants. This study investigated the physical and antibacterial attributes of dental sealant enriched with phytoncide. Methods: Phytoncide was mixed with a commercially available dental sealant (Clinpro) at concentrations of 0 (control), 1.5%, 3%, and 4.5% by weight (wt%). The flexural strength, curing depth, and wettability of the dental sealant were measured. Antibacterial properties against Streptococcus mutans were evaluated through the enumeration of colony-forming units. Statistical analyses employed one-way variance analysis followed by Tukey's test (p<0.05). Results: The dental sealant containing 3% phytoncide showed no significant difference in flexural strength and curing depth compared with that in the control group (p>0.05). The flexural strength and curing depth decreased with increasing phytoncide content and significantly differed in sealant containing 4.5 wt% phytoncide (p<0.05). Wettability did not differ between the experimental and control groups (p>0.05). The antibacterial properties of the sealant containing 1.5% phytoncide were the same as those of the control group (p>0.05). The bacterial viability was significantly reduced in groups containing 3% and 4.5% phytoncide compared with that in the control group (p<0.05). Conclusion: Dental sealants incorporating phytoncide have a promising potential as antibacterial dental materials.

Objectives: The purpose of the study was to investigate the cumulative dental caries rate of pit and fissure sealant in community public health program from 2005 to 2008 follow-up. Methods: The subjects were 4,768 students of 34 elementary schools in Gimcheon. The survey included direct oral examination and cumulative retention rate of pit and fissure sealant from 2005 to 2008. Data were analyzed using PASW statistical package version 18.0 and the level of significance was set at p<0.05. Results: The cumulative retention rate of sealant was 18%, 25%, and 33% after 1 year, 2 years, and 3 years, respectively. In addition, the cumulative retention rate of lower teeth was higher than that of upper teeth. Cumulative dental caries rate increased in sealed group and no sealed group. The cumulative dental caries rate decreased owing to tooth brushing frequency in sealed group and no sealed group. Conclusions: Regular and timely tooth brushing can maintain good oral health condition after tooth sealing. The school based oral health education can prevent loss of sealant and secondary caries.

Dental caries is the first disease to cause the pathological extraction of teeth in children. The complete prevention of dental caries is not achieved by toothbrushing alone. The use of fluoride and pit and fissure sealant is regarded as key tools to prevent dental caries. Fluoride-containing tablets or multi-vitamins and community water fluoridation can be used as systemic application techniques. Professional fluoride application, fluoride iontophoresis on teeth, fluoride mouth rinsing and fluoride-containing toothpaste can be used as local application techniques. Pit and fissure sealant is mainly used to prevent dental caries on occlusal surfaces of premolars and molars. Sweeteners not to occur dental caries has been developed to substitute sucrose. Dental erosion increases according to the high consumption of acidic soft drink or beverages. The appropriate use of fluoride and pit and fissure sealant are recommended to prevent dental caries effectively and the education is required to reduce the consumption of acidic soft drinks or beverages to decrease dental erosion.

To provide basic data necessary to develop an efficient sealant project as a public oral health project, this study applied a sealant through a photodimerization method to first-graders from public primary schools in the Dong-gu Health Center in Incheon and conducted a survey on favor and knowledge of the sealant project with their parents and, consequently, obtained the following results. 1. 84.7% of the parents knew a sealant and most of them got the knowledge from a dental clinic (35.7%) or a school (31.6%). 2. A large majority of respondents (86.2%) were satisfied with sealant application; many parents (75.8%) checked for maintenance of the sealant; and 75.6% demanded reexamination after sealant application. 3. As factors associated with acceptance of a sealant, high recognition of a sealant, much experience of visiting a dental clinic, and parents' great concern about children's dental health were related to high sealant application. To put the results together, it is desirable to develop the sealant project by the Dong-gu Health Center in Incheon actively as a public oral health project.

In 2001, as a subject of this study, the first grade 165 kids in Yomju elementary school had been guided in pit and fissure sealant, fluoride rinse, group tooth brushing, and Dental health education as a part of oral disease preventive program. From the data, this author has estimated incremental dental health care program in school dental clinic in order to make it more effective and enlarge it. For that purpose, the program has been continued at six month intervals for two years. The retention condition of pit and fissure sealant in first molar and DMF rate had been investigated. The conclusions are as follows: 1. Full and partial retention of pit and fissure sealant was measured as 80.69% in maxillary right first molar, 83.20% in maxillary left first molar, and 86.72% in mandibular right first molar, and 86.28% in mandibular left first molar. 2. Retention of pit and fissure sealant in first molar was measured as 76.55% in maxillary right first molar, 81.03% in maxillary left first molar, 80.65% in mandibular left first molar, and 82.03% in mandibular right first molar. 3. Among Yomju elementary school students, DMF rate was measured as 8.7%, and DMFT index as 1.03. However, in Yangdong elementary school students the former was measured as 13.8% and the latter as 1.76. When the DMF rate difference between Yomju and Yangdong elementary school kids was considered, the oral health condition of the former was much better than that of the latter because the former had received incremental dental health care program for two years and on the other hand, the latter had not. So it is necessary that we should enlarge school dental clinic, improve and keep students' oral health.

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.
