초록

본 연구의 목적은 산부식 시간과 접착제 적용에 따른 유구치 치면열구전색제의 미세인장 결합강도를 평가하여 비교하는 것이다. 40개의 발거된 건전한 하악 유구치를 선정하여 산부식을 시행하지 않은 군과 산부식을 각각 15, 30, 60초 시행한 군으로 분류하였다. 이를 다시 접착제를 적용하지 않은 군과 적용한 군으로 나누었다. 각 군의 치아에 치면열구 전색제를 도포하여 시편을 제작한 후 미세인장 결합강도를 측정하였다. 산부식을 시행한 15, 30, 60초에 따라 미세인장 결합강도는 유의한 차이가 없었다. 전색제를 적용하기 전에 접착제를 적용한 경우가 산부식만 시행한 경우보다 더 높은 결합강도를 보였으며(p < 0.05), 산부식 시간에 따른 유의한 차이는 없었다. 결론적으로, 유구치의 교합면 법랑질에서 산부식 시간이 15초 이상이면 전색제의 미세인장 결합강도는 유의하게 증가하지 않았으며, 치면열구전색제 도포 전에 접착제를 적용하는 것은 결합강도를 증가시켰다.

The aim of this study was to evaluate the effect of etching time and bonding agents on bond strength of sealant applied to the occlusal surface of primary molars. Forty non-carious exfoliated human primary molars were included in the study. The teeth were randomly divided into 4 groups for measurement. For group I, no acid etching treatment was used. For group II, III, and IV, acid etching gels were applied on the occlusal surface for 15, 30, and 60 seconds, respectively. Each group was divided into 2 subgroups; one group was treated with bonding agents on the enamel while the other was not. Microtensile bond strength was evaluated using a universal testing machine. There were no statistically significant differences in bond strength with varying duration of etching among groups. The results revealed that the use of bonding agents prior to application of fissure sealant increased the bond strength(p < 0.05). It could be concluded that etching time greater than 15 seconds does not significantly enhance the bond strength, but the use of bonding agents as an intermediate layer between the primary molar and fissure sealant would be beneficial in increasing the bond strength.
