  • Objectives: This study was conducted to examine the degree of dental fear according to the experiences of the preventive dental care services. Methods: A self-administered survey was conducted in the subjects of male and female teenagers who lived in Seoul and Gyeonggi-do areas, and 231 copies of collected data for a month from July 26, 2017 were analyzed to find the following results. Results: In terms of the experiences of the preventive dental care services, they were classified in the order of preventive scaling (67.5%), education of toothbrushing (60.6%), fluoride application (49.8%) and sealant (44.2%). For the degree of dental fear according to their general characteristics, treatment avoidance factor ($2.56{\pm}1.19$) in the married was higher than that in the unmarried. All of treatment avoidance, physiological response and fearful stimulus induction factor, and the entire degree of fear were higher when there were experiences of the preventive dental care services than those without such experiences. The factors affecting the degree of dental fear included dental health conditions, experiences of toothbrushing education, sealant and fluoride application. In case those without the experiences considered their dental health condition was not healthy, the degree of dental fear was increased. Conclusions: This study verified that the degree of dental fear was increased in case no experiences of the preventive dental care services. Therefore, it is necessary to seek out the measures for promotion of the preventive dental care services, to reduce the degree of dental fear and enhance the dental health.

  • 불소도포와 치면열구전색은 치아우식을 예방하기 위한 목적으로 임상에서 널리 병용하여 사용되고 있지만, 불소가 치면열구전색제의 표면 구조를 변화시켜 미생물이 서식할 조건을 마련하여 수복물의 수명을 단축시키는 원인이 될 수 있다. 이에 본 연구에서는 현재 치과 임상에서 많이 사용되고 있는 레진계 실란트 Concise와 Eco-S를 사용하였고, 대표적인 불소도포제재 1.23% APF gel과 5% NaF Fluoride Varnish가 치면열구전색제의 표면 구조에 미치는 영향을 평가하기 위해 제작된 치면열구전색제시편을 각각 5군으로 불소제재를 처리하지 않은 I군, APF gel 1분간 처리한 II군, APF gel 4분간 처리한 III군, Fluoride Varnish 1분간 처리한 IV군, Fluoride Varnish 4분간 처리한 V군으로 분류하여 마모실험에 의한 무게변화를 측정하였고, 광학현미경을 이용하여 표면구조를 관찰하여 다음과 같은 결론을 얻었다. 1. 치면열구전색제 Concise를 이용한 마모실험에서 불소제재를 처리하지 않은 I군에 비하여 APF gel 4분간 처리한 III군에 무게 감소가 증가하였으며, Fluoride Varnish 4분간 처리한 V군에서 무게 감소가 적으며(p<0.05), Eco-S를 이용한 마모실험 결과 또한 같았다(p<0.05). 2. 광학현미경으로 표면의 변화를 관찰한 결과 APF gel을 도포한 경우 기질의 소실로 필러가 두드러진 양상을 보였으며, 각 군 별로는 APF gel 4분간 처리한 III군, APF gel 1분간 처리한 II군, 불소제재를 처리하지 않은 I군, Fluoride Varnish 1분간 처리한 IV군, Fluoride Varnish 4분간 처리한 Ⅴ군의 순으로 표면 거칠기가 감소되는 결과를 보였다. 결론적으로, 치면열구전색과 불소도포를 당일 시행하는 경우, 불소도포제를 1.23% APF gel 사용 시 4분 보다 1분 도포하며, 1.23% APF gel보다는 5% NaF Fluoride Varnish 도포하는 것이 치면열구전색제의 표면 구조에 영향을 줄일 수 있다고 사료된다.

  • The purpose of this study was to evaluate the remineralization effects of fluoride-containing sealant on the artificially created enamel carious lesions. The fluoride release from the specimen of fluoride-containing sealants, the effect on enamel acid solubility and micro-hardness from the experimental sealants when applied to carious enamel surfaces were investigated. The obtained results were as follows; 1. Fluoride was a rapid rate of release during the first day, with the amount diminishing with time. The amount of fluoride released from Fuji Ionomer type III was higher than that from Teethmate-F and Helioseal-F during the 28 days of immersion(P<0.05). 2. The enamel solubility of carious enamel surface was higher than that in the Teethmate-F, Helioseal-F, and Fuji Ionomer type III (P<0.05), and there was no significant difference with Teethmate-A and Helioseal(P>0.05). 3. The microhardness value of carious enamel surface was lowest. However, there was no significant difference between the other sealants with respect to their effects on enamel hardness(P>0.05).

  • Objectives: The objectives of this study were to investigate the changes in bisphenol A (BPA) concentrations in urine from before to after sealant filling and the relationship between BPA and the number of teeth with sealed surfaces. Methods: Thirty-one children aged 6 and 7 years from three elementary schools in Daegu city who did not have any sealant and resin filling were selected as subjects. Urine samples were collected before and after sealant filling until 24 hours, with informed consent from their caregivers. The BPA concentration in all the collected urine samples was analyzed at Seegene Medical. Statistical analysis was performed using the Friedman test, Scheirer-Ray-Hope test, and the repeated-measures generalized linear mixed model of SPSS version 22.0. Results: The BPA concentrations increased from $3.49-{\mu}g/g$ creatinine before to $4.91-{\mu}g/g$ creatinine 2-3 hours later and to $4.15-{\mu}g/g$ creatinine after 24 hours. The more teeth with sealed surfaces, the higher the BPA concentration in children, but the difference was not statistically significant (P>0.05). Conclusions: The BPA concentrations were highest at 2-3 hours after sealant filling and decreased at 24 hours. Exposure to the sealant appears to have a meaningful correlation with the concentration of BPA in the urine of children.
