전통적인 3단계 total-etching 시스템인 제 4세대 상아질 접착제로부터 술식의 단순화를 이루며 진화한 제 5, 6세대 및 최근에 소개된 제 7세대 상아질 접착제를 상아질 표면처리방식과 적용단계별로 구분하여 bovine teeth 상아질에 대한 미세인장결합강도를 측정하여 그 효용성을 비교평가하였다. Bovine incisor의 상아질 표면을 노출시키고, 적절한 표면처리 후 제조사의 지시에 따라 5종의 상아질 접착제; 제 4세대로 Scotch BondTM Multipurpose(3M ESPE, USA), AdperTM Single Bond 2(3M ESPE, USA), 제 5세대 Clearfil. SE Bond(KURARAY, JAPAN), 제 6세대 AQ BondTM(SUN MEDICAL, JAPAN), 제 7세대 Clearfil. tri-S Bond(KURARAY, JAPAN)를 각각 적용하여 미세인장결합강도를 측정하고 접착계면의 파절양상을 관찰하였다. 연구결과 미세인장결합강도는 Clearfil. SE Bond군에서 가장 높았으며 다음으로 Scotch BondTM Multipurpose군, AdperTM Single Bond 2군, AQ BondTM군, Clearfil. tri-S Bond군의 순으로 나타났다. 계면의 파절양상은 상대적으로 미세인장강도가 높게 나타난 Scotch BondTM Multipurpose, AdperTM Single Bond2, Clearfil. SE Bond군은 레진의 응집성 파절이 많이 발생하였고 상대적으로 미세인장강도가 낮은 AQ BondTM, Clearfil. tri-S Bond 군의 경우에는 대부분 접착성 파절이 관찰되었다. 이상의 결과를 종합하면 상아질 접착제의 미세인장결합강도는 각 접착시스템별로 다소의 차이를 보이며, 특히 제 6, 7세대 상아질 접착제가 이전 세대보다 낮은 것으로 나타났다.
Abstract
The purpose of this study was to compare the microtensile bond strength to bovine dentin of several adhesives (SM, Scotch BondTM Multipurpose; SB, AdperTM Single Bond 2; SE, Clearfil. SE Bond; AQ, AQ BondTM TS, Clearfil. tri-S Bond). Except SM and SB, they have a simplified one- or two-step application protocols in compare with the dentin adhesives conventional three-step protocols. For the microtensile bond strength test, the labial surfaces of bovine incisors were used. Following exposure of dentin layer, according to their manufacturer’s directions, each dentin adhesives were applied and composite resin blocks were constructed. The teeth were sectioned for specimen and tested microtensile bond strength. Also observed the fracture mode of interface. The obtained results were as follows : 1. The microtensile bond strength values ranged from 51.34 to 24.04 MPa on dentin(in decreasing order, SE, SM, SB, AQ and TS). 2. The highest microtensile bond strength was by SE and SM on bovine dentin, and the lowest by AQ and TS. 3. SM, SB and SE showed cohesive failures and adhesive failure but AQ, TS presented almost adhesive failures. In summary, microtensile bond strengths of single-step adhesives (AQ and TS) on bovine dentin were significantly lower than those of multi-step adhesives (SM, SB and SE) (p<0.05).
