Abstract

In order to explore microleakage in class V cavity based on different kinds of several dentin adhesive and composite resin, 2 kinds of composite resin was restored and exposed after applying 4 kinds of dentin adhesives. Deposited in methylene blue solution for 4 hours and cut in parallel with tooth longitudinal axis. By observing dye penetration level of enamel and dentin margins of each restored resin following conclusion was obtained. 1. In composite resin Filtek Z350XT Universal (3M/ESPE Dental Products, USA) in enamel margin, Easy Bond (3M/ESPE Dental Products) showed the lowest microleakage and this leakage was represented to be high in the order of Single Bond 2 (3M/ESPE Dental Products), Scotchbond Multi-Purpose (3M/ESPE Dental Products) and Cearfil SE Bond (Kuraray Medical Inc., Japan). In case of Filtek Z350XT Flowable (3M/ESPE Dental Products), Scotchbond Multi-Purpose showed the lowest microleakage and this leakage was represented to be high in the order of Single Bond 2, Clearfil SE Bond and Easy Bond. 2. In case of Filtek Z350XT Universal in dentin margin, Easy Bond showed the lowest microleakage and this leakage was represented to be high in the order of Scotchbond Multi-Purpose, Single Bond 2 and Clearfil SE Bond. In case of Filtek Z350XT Flowable, Scotchbond Multi-Purpose and Single Bond showed the lowest microleakage and this leakage was represented to be high in the order of Clearfil SE Bond and Easy Bond. 3. In all the groups excepting S-U group (Single Bond 2+Filtek Z350XT Universal), enamel margin showed more higher microleakage than that of dentin margin. 4. There was a difference between enamel and dentin margin among each group but it was not significant statistically (p>0.05). When summarizing this result, it is considered that composite resin and dentin adhesive could be applied selectively and particularly in case of applying 1-step self-etching dentin adhesive, this method would be advantageous for manipulation convenience and shortening of operation time.

5급 와동에서 상아질 접착제와 레진의 종류에 따른 미세누출을 알아보고자 64개의 건전한 상 하악 소구치 및 대구치에 5급 와동을 형성하였다. 형성된 와동에 4종의 상아질 접착제를 각각 적용하고 2종류의 복합레진을 수복하여 법랑질과 상아질 변연부 색소침투 정도를 실체현미경하에서 23배율로 관찰하여 미세누출 점수를 기록한 후 각 군 간의 유의성을 검정하였다. 연구 결과, 5급 와동 수복 시 상아질 접착제와 레진의 종류에 따른 미세누출은 통계적으로 유의하지 않았다. 그러나 복합레진 Filtek Z350XT Universal 적용 시 1단계 자가부식 접착제 Adaper Easy Bond에서 미세누출이 낮게 나타났고, 유동성레진 Filtek Z350XT Flowable 적용 시 3단계 전부식 접착제 Adaper Scotchbond Multi-Purpose, 2단계 전부식 접착제 Adaper Single Bond 2에서 미세누출이 낮게 나타났다. 따라서 복합레진 및 상아질 접착제의 선택적 적용이 가능하며 특히, 1단계 자가부식 상아질 접착제 적용 시 조작의 편이성과 시술시간의 단축에 유리할 것으로 생각된다.
