Abstract

The purpose of this study was to evaluate the effects of cyanate methacylate on the shear bond strengths to bovine dentin surfaces as a dentin primers. Seven experimental adhesives were made with different mass fraction of Isocyanatoetylme-thacrylate (IEM), 40wt% HEMA (Wako Pure Chemical Industries Osaka, Japan), 0.6% camphoroquinone, 0.4% amine and ethanol as balance dentin bonding agents (0, 2, 4, 6, 8, 10, 12%) were made and applied on the surface of bovine dentin specimens of 7 experimental groups. Shear bond strengths were measured using a universal testing machine (Instro 4466). To identify the ratio and modes of cohesive failures, microscopic examinationn was performed. The ultra-structure of resin tags were observed under scanning electron microscope. The results were as follows ; 1) A higher shear bond strengths (33.62 MPa) in group 8% of Cyanate methacrylate to dentin were found, but there were no statistically significancy between Groups (p > 0.05). 2) The higher ratio of cohesive failures mode in group 2, 6, an 10% could be seen than that in any other groups. 3) A shorter resin tags were observed in all experimental groups. This could be resulted that the preventing from the cyanate methacrylate penetrate into dentin owing to reacting it with dentin collagen. Therefore the resin tags were shorter in lengths. Whether the higher bonding strengths of dentin bonding agents can be affected was not been assured with statistic results. The results indicated that the relation between tensile strengths of the dentin adhesives to bovine dentin and resin tags formed into the dentin could not affected. The main reason of increasing the shear bond strength to bovine dentin in experimental groups could not be assured.

접착제의 술식을 간편하게 하고 효과적이며 안정적인 접착강도를 지닌 상아질 접착제를 개발하고자 isocyanate methacrylate의 농도를 달리해 상아질에 적용하여 전단결합강도를 측정하고 응집파괴양상을 분석, 평가하였다. Isocyanate methacrylate의 농도에 따라 0% (대조군), 2%, 4%, 6%, 8%, 10%, 및 12%의 7개 실험군으로 분류하였으며 , Instron (No.4466.USA)를 이용하여 복합레진의 전단 결합강도를 측정하고 Resin tag 및 응집파괴를 주사전자현미경으로 관찰해 다음 결론을 얻었다. 1. Cyanate methacrylate 8%군이 가장 높은 전단 결합강도는 나타내었으나 (33.62 KPa), 통계학적 유의성이 없었다 (P > 0.05). 2. Cyanate methacrylate 2% ,4% 및 6%군은 응집성파괴빈도가 대조군 (0%군)과 비교하여 높게 나타났다. 3. Cyanate menthacrylate군에서 레진tag의 길이는 짧게 나타났다. 이상의 연구의 결과로 cyanate methacrylate가 collagen과 반응하여 상아질 내로 침투를 방해하며 레진 tag의 길이를 짧게 하며 상아질의 유기성분과의 반응에 의하여 결합강도는 높아질 수 있으나, 상아질 자체의 강도가 낮아질 수 있어 상아질에 대한 결합강도의 실질적인 증가는 확인할 수 없었다.
