Abstract
Recently, self-etching adhesive system have been developed and bonding procedures simplified into one or two steps, which are simultaneously applied to both enamel and dentin. These systems are easy to use and have the potential for good clinical success. The purpose of this study is to evaluate in vitro the microleakage on the cementum/dentin and enamel walls in composite resin restoration of Class V cavities, regarding the use of different adhesive systems. 30 human premolars were divided into 3 groups. A standardized Class V preparation was prepared on the buccal and lingual surface of each premolar. The preparation were made parallel to the cementoenamel junctions, with the gingival half of the preparation extending 1mm apical to the cementoenamel junction. After adhesive system was applied to teeth as manufacture's recommendation, hybrid resin composite was filled in bulk into the preparation and light polymerized according to manufacturer's recommendations. Specimen were stored in distilled water at
최근 자가 부식형 접착 시스템이 개발되어 법랑질 및 상아질에 모두 적용할 수 있고, 임상적 술식을 단순화 시켰다. 이 접착 시스템은 적용하기 용이하고 임상적으로도 법랑질 및 상아질에 높은 결합강도를 보인다고 보고되고 있다. 이 연구는 in vitro 상에서 복합레진 5급 와동의 법랑질 및 상아질 경계에서 전부식 처리를 동반한 one-bottle 접착시스템과 자가 부식형 접착 시스템을 사용하였을 때 미세 누출을 비교하기 위해 시행하였다. 교정적 목적으로 발치된 30개의 소구치를 무작위적으로 3개 군으로 나누었다; 1 군 (Single
