Since the introduction of pit and fissure sealants in the early 1970's, many studies have been published amply documenting the efficacy of these materials as caries-preventive agents. However, the acceptance of the technique by dentist has been questionable. This survey was investigated the attitudes toward and use of pit and fissure sealants by dentist in Chonbuk area. The results were as follows: 1. Utilization of pit and fissure sealants is very high. Only 15% of dentists never use pit and fissure sealants, whereas 85% generally use pit and fissure sealants. 2. Most dentists reported that their knowledge of pit and fissure sealants was gained through dental schools education. 3. Concern about difficult to sell' to patient, poor retention of pit and fissure sealants and unsubstantiated by research were given as the main reasons why pit and fissure sealants was not used. 4. Patient demands and various educate program were given as important factors that would lead to increase use of pit and fissure sealants.

치면열구전색은 잘 시행하지 못한 경우 오히려 우식발생을 가릴 수 있어 위험하다. 따라서 치면열구전색의 올바른 적용방법에 대한 이해와 재고가 필요하다. 치면열구전색 시행하기 위해서는 반드시 recall-check이 전제되어야 하는데, 치면열구전색재 시술 환자의 70%가 recall이 되었을 때 병원 경영이 효율적으로 이루어지고 있다는 평가를 내릴 수 있다. 치면열구전색재 도포시 임상가들이 가장 관심 있게 추구하는 2가지 사항은 첫째 치면열구전색재가 소와 및 열구내로 깊숙이 침투하도록 하는 것과 둘째 치면열구전색재와 치면 사이의 gap(변연누출, marginal leakage)을 최소로 발생하게 하는 것이다. 이는 모두 치면열구전색재의 유지력을 좋게 하기 위한 것이며 이는 치면열구전색의 성공/실패와 직결된다. 그러나 탈락되지 않게 할 수는 없어도 더 오랫동안 붙어 있도록 하는 노력은 필요하다. 본 종설에서는 치면열구전색재 유지력을 강화하기 위한 방법으로 치면열구전색재의 재료학적 검토, 유지력에 관계되는 요소, 교합면 소와 및 열구 세척 소와와 열구 내로의 침투도를 높이는 방법, 미세누출을 줄일 수 있는 임상 기술 등에 대해 살펴보고자 하였다. 치면열구전색재의 유지력에 관여되는 요소가 매우 많고 다양하므로 이에 대한 기본적인 이해와 함께 도포 과정에서의 술자의 섬세함과 정성이 전제되어야 한다.

Purpose: To evaluate reliability of Q-ray view (Aiobio Inc,. Seoul, Korea) for assessing retention status of pit and fissure sealants. Methods: Pit and fissure sealants of 58 permanent molars from 15 third-grade students were examined. Posterior teeth with ≥1 pit and fissure sealants applied to the occlusal surface for >6 months were examined. The teeth were examined using traditional visual-tactile assessments and combined Q-ray view. Pit and fissure sealants were evaluated by assessing marginal plaque, marginal discoloration, marginal integrity, retention, and presence of caries. Fleiss kappa and Cohen's kappa values were calculated to compare inter- and intrarater agreements between visual-tactile and combined Q-ray view assessments. Results: Regarding interrater agreement in visual-tactile assessments, K values of Cohen's kappa for marginal plaque, marginal discoloration, and presence of caries were 0.22-0.57, 0.36-0.57, and 0.43-0.61, respectively, and agreements ranged from slight to moderate. When combined with Q-ray view, the values were 0.81-0.89, 0.69-0.88, and 0.80-0.90, respectively, and agreements ranged from substantial to nearly perfect level, indicating statistical significance. Marginal plaque (0.81-0.83), marginal discoloration (0.57-0.89), and presence of caries (0.69-0.91) showed higher agreements in combined Q-ray view than in visual-tactile assessments, and kappa values of marginal plaques were significantly higher in combined Q-ray view than in visual-tactile assessments. Conclusion: Evaluating retention status of pit and fissure sealants using Q-ray view showed higher reliability than using visual/tactile assessments for marginal plaque, marginal discoloration, and presence of caries. Therefore, Q-ray view may be used to assess the retention status of pit and fissure sealants.

The purpose of this study was to investigate whether fluoride-releasing pit and fissure sealant was more effective in preventing caries than conventional non-fluoride-releasing sealant. Specimens 8mm in diameter were made from sound bovine enamel. Fluoride-releasing pit and fissure sealant(Helioseal F, Vivadent, Schaan, Liechtenstein) and non-fluoride-releasing sealant(Helioseal, Vivadent, Schaan, Liechtenstein) were applied to the specimens and artificial caries was induced. Microhardness and the depth of the carious lesion was measured. The following results were obtained: 1. In group 2, sealed with fluoride-releasing sealant, there was a 58.4% decrease in microhardness. This was significantly less than the 84.4% decrease observed in group 1, sealed with non-fluoride-releasing sealant(p<0.01). 2. The average depth of the artificial carious lesion in group 2 was $30.1{\pm}9.8{\mu}m$. In group 1, sealed with non-fluoride-releasing sealant, the lesion was significantly deeper with an average depth of $58.5{\pm}4.9{\mu}m$(p<0.01). 3. Fluoride-releasing pit and fissure sealant was more anticariogenic compared to non-fluoride-releasing sealant.

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.

Objectives: The purpose of this study was to interpret regional disparities in the number of teeth sealed with pit and fissure sealants, identify the factors that affect these disparities and find solutions for the same. Methods: Data were collected from the National Health Insurance Service and Korean statistical information service using metropolis-city-rural area dental health infrastructure variables, regional health behavior variables, and local finance-related variables. Results: In 2015, the number of teeth sealed with pit and fissure sealants per 100 people was higher in the metropolis or city than in the rural area. There was a positive correlation between the number of teeth sealed with pit and fissure sealants and the number of dentists, dental hygienists, dental institutions, standardization rate of subjective awareness of well-being, standardization rate of brushing after lunch, and the proportion of welfare budget in the general budget. There was a negative correlation with the annual standardization rate of health institution use, the standardization rate of unused medical services, and the local government's financial independence. According to the final model of the multiple regression analysis, while the impact of infrastructure on dentistry was not statistically significant, the statistical significance of standardization rate of brushing after lunch, the local government's financial independence, and the proportion of welfare budget in the general budget were maintained. Conclusions: To reduce regional disparities in the volume of use of pit and fissure sealants, it was concluded that it may be effective to select regions with a consideration of the level of regional economic power, implement separate and appropriate policies and projects, and improve the awareness in residents.

본 연구는 기존의 치면열구전색재 ConciseTM에 세륨옥사이드 나노입자(Cerium oxide nano particles; CNPs)를 0-4.0 wt%를 첨가하여 새로운 치면열구전색재를 제조하여 물리적 성질과 세포독성을 평가하였다. 물리적 성질은 중합깊이, 물흡수도와 용해도를 측정하였고 세포독성평가는 불멸화된 구강점막세포(Immortalized human oral keratinocyte (IHOK))를 이용하여 MTT assay법으로 평가하였다. 실험 결과 중합 깊이는 CNPs 첨가량이 증가할수록 감소하였고, 용해도는 CNPs를 2.0 wt% 첨가된 실험군에서 가장 낮은 값을 보였으며 물흡수도는 각 실험군별 유의한 차이는 나타나지 않았다(p>0.05). 세포독성 실험 결과는 모든 실험군에서 높은 세포 생존율을 보였다. 이는 CNPs가 물리적 성질을 크게 약화 시키지 않으며 세포독성을 나타내지 않았으므로 생체 적합성을 입증하였다. CNPs의 특성을 고려하여 향후 CNPs의 효율적인 분산 기술에 대한 추가 연구가 필요할 것으로 사료된다.

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.
