본 연구는 치면열구전색 하방의 우식이 이차우식에 미치는 영향을 평가하기 위해 DIAGNOdent를 이용하여 소구치 및 대구치 교합면 446부위를 4개의 군으로 분류하였고 상방에 치면열구전색을 시행한 뒤 이차우식을 유발시켜 DIAGNO dent로 재측정하였다. 또한 치과 업무 관련 종사자들을 대상으로 치면열구전색에 대한 인식도 및 실태를 조사하여 다음과 같은 결과를 얻었다. 시진 및 탐침 시 법랑질우식군에서 치면열구전색 후 이차우식이 가장 높게 나타났으며 초기우식군, 착색군, 건전부위군 순으로 통계적으로 유의한 차이를 보였다(p<0.05). 치면열구전색 전 치아우식증 진단 방법으로는 시진이 가장 높은 비율로 나타났다. 레이저 우식진단기에 대해 56.6%가 모르는 것으로 나타났으며, 91.6%가 보유하지 않은 것으로 나타났다. 치면열구전색 후 이차우식 발생의 원인은 치면열구전색제가 깨져서 하방에 우식이 생긴 경우가 가장 많았다. 이상의 결과를 종합하면, 치면열구전색 하방의 우식이 전색 후 이차우식 유발에 영향을 미치는 것으로 나타났다. 따라서 치면열구전색 후 이차우식을 예방하기 위해서는 열구 내 우식 정도를 정확하게 진단 평가하는 것이 중요하며, 보다 객관적으로 진단할 수 있는 우식 진단기기의 사용에 대한 교육 및 홍보가 필요할 것으로 생각된다.

This study was designed to investigate the using status and awareness of pit and fissure sealant, and how it affects on secondary caries when performed on above of initial caries. After classifying 446 occlusal surface into four groups, performed pit and fissure sealant, induced artificial caries, used DIAGNOdent (Kavo) to measure degree of secondary caries. Also, distributed a questionnaire on dental clinic in metropolitan area to find out using status and awareness of pit and fissure sealant, the following results were obtained. 1) On inspection and percussion, Group 4 corresponding to the enamel caries showed the highest secondary caries after sealant and was statistically significant difference in the order of initial group, stained group, sound group (p<0.05). 2) Inspection showed the highest percentage on tooth fissure caries diagnostic methods before sealant. 3) 56.6% didn't know about DIAGNOdent, 91.6% didn't have it. 4) In clinically, the most cause of secondary caries after sealant was a broken sealant, making caries on the downward. Based on the results of above study, degree of caries under sealant could affect on secondary caries, needs publicity about the use and necessity of objective fluorescence device.

문제 정의
To date, there are several researches about the effects and leakage of the sealant, but there are few reports whether sealant on initial caries can cause secondary caries. Therefore the purpose of this study is to investigate the influence of the sealant on the secondary caries when the sealant applies on initial caries and analyze the using status and awareness of laser caries diagnostic tool, DIAGNOdent (Kavo, Biberach, Germany), and sealant.
This study was designed to know how caries under sealant affects on secondary caries. After dividing 446 areas of occlusal surfaces into four groups, we performed pit and fissure sealant on the upper side of fissure, caused secondary caries and used DIAGNOdent to measure degree.
가설 설정
It is impossible to block any moisture or saliva completely on dental treatment38). So we considered that using rubber dam is a necessary part for successful sealant.
제안 방법
This study was designed to know how caries under sealant affects on secondary caries. After dividing 446 areas of occlusal surfaces into four groups, we performed pit and fissure sealant on the upper side of fissure, caused secondary caries and used DIAGNOdent to measure degree.
Also, in this study, as a results of the questionnaire about diagnostic methods before sealant, visual inspection were the most common and explorer, radiograph, percussion in order. This means that clinicians depend on visual inspection and explorer when they diagnosis.
The occlusal surface of the tooth was performed oral prophylaxis. And tooth occlusal surface 446 areas were divided into four groups according to the degree of discoloration and caries by visual inspection, probe and laser fluorescence caries diagnosis (Table 1).
Each item of the questionnaire was carried out frequency analysis. Used one-way ANOVA on evaluating to compare the groups of artificial caries induced degree.
대상 데이터
Person in charge to apply sealant was 55.9% for ʻdentist', 38.6% for ʻdental hygienist', 5.5% for ʻnurse's aide'.
Respondents were consisted of 53.6% dental hygienists, 31.3% nursing assistants, coordinators of 9.6%, 5.4% dentist.
We used the permanent premolar and molar, which was extracted for the purpose of orthodontic treatment, the occlusal surface area of 446 were used as test subjects. And the Ultraseal XT plus (Ultradent, St.
데이터처리
Each item of the questionnaire was carried out frequency analysis. Used one-way ANOVA on evaluating to compare the groups of artificial caries induced degree. And used Dunnett T3 for multiple comparison.
The same letter denoted that there was no significant difference between groups by Dunnett T3 multiple comparison. p-values were determined by one-way ANOVA.
성능/효과
Cause of secondary caries was ‘low strength of sealant' 47.3%, ‘low flowability of sealant' 26.1%, ‘cariogenic bacteria under sealant' 20.2%, ‘product problem in itself' 4.3% and ‘others' 2.1% (Table 5).
In this research that whether secondary caries occur after sealant, 63.6% said ʻyes', and cause of secondary caries was ʻlow strength of sealant' 47.3%.
The number of patients who had sealant treatment per week was most common at ‘less than four’ as 60% and 5∼9 people, 10∼19 people, 20∼29 people, 30 or more were in the order. The most common diagnostic method before sealant was visual inspection 39.9%, followed by explorer 20.4%, x-ray 18.5%, percussion 9.7%, oral camera 8.9% and laser fluorescence detection 2.6%. Person in charge to apply sealant was 55.
