초록
이 논문의 목적은 기능성 모노머를 함유한 8세대 접착제의 적용시간 감소와 인산 산부식 여부가 유치에서 접착능에 미치는 영향을평가하는 것이다. 80개의 우식이 없는 유구치를 선정하였고, 접착제의 종류에 따라서 2그룹으로 분류하였다(G–premio bond, Single bond universal). 각 그룹은 적용 시간와 인산 산부식 여부에 따라서 그룹당 10개씩, 총 4개의 하위그룹으로 추가 분류하였다. 각 하위그룹은 절반으로나누어, 5개의 시편은 전단결합강도 측정 후 주사전자현미경을 촬영하여 파절양상을 확인하였고, 다른 5개의 시편은 미세누출을 측정하였다. G-premio bond는 적용시간와 인산 산부식 여부에 따른 결합강도와 파절양상, 미세누출의 유의한 차이가 관찰되지 않았다. Single bond universal은 적용시간을 길게 한 경우가 적용시간이 짧은 경우에 비해서 유의하게 높은 전단결합강도를 보였다(p = 0.014). 모든그룹에서 나타난 전단결합강도는 임상적으로 허용 가능한 전단결합강도인 17 MPa 보다 높았다. G-premio bond는 인산 산부식 없이 적용시간을 줄여서 사용하는 방법이 가능하다.
Abstract
The purpose of this study was to evaluate the effect of application time and phosphoric acid etching of 8th generation adhesives containing functional monomer on adhesive performance in primary teeth. 80 extracted non-carious human primary teeth were selected and divided into 8 groups based on 3 factors: (1) adhesive: G-Premio bond and Single bond universal; (2) application time: shortened time and manufacture’s instruction; (3) acid etching mode: self-etching and total-etching. Shear bond strength was measured using a universal testing machine, and fractured surface were observed under scanning electron microscope. Microleakage was evaluated by dye penetration depth. G-Premio bond were not significant different in shear bond strength and microleakage depending on application time of adhesive and acid etching mode. In Single bond universal, shear bond strength of short application time was significantly lower than that of long adhesive application time (p = 0.014). Clinically applicable shear bond strength values (> 17 MPa) were identified in all groups. These results suggested that G-Premio bond be used clinically for a short application time without phosphoric acid etching.
