Abstract

This study compared the coronal microleakage of three restorative materials used to seal the access cavity in root treated teeth. Thirty six teeth were prepared and three experimental groups were obturated and the access cavity filled with different materials; Group A--Intermediate Restorative Material, Group B--Fuji II and Group C--Dyract AP. Microleakage was assessed by Indian ink penetration. The mean coronal dye leakage for Group A was 0.895 mm, for Group B 1.914 mm and for Group C 3.245 mm. There was significantly (p < 0.05) more dye leakage in teeth restored with Dyract AP compared to those with Fuji II or IRM.

摘要

本研究比较了用于封闭根管治疗牙齿髓腔的三种修复材料的冠部微渗漏情况。制备了36颗牙齿，将其分为三个实验组并进行充填，髓腔用不同材料充填；A组——中间修复材料，B组——富士Ⅱ型材料，C组——Dyract AP材料。通过印度墨水渗透评估微渗漏情况。A组的平均冠部染料渗漏为0.895毫米，B组为1.914毫米，C组为3.245毫米。与用富士Ⅱ型材料或中间修复材料修复的牙齿相比，用Dyract AP材料修复的牙齿染料渗漏明显更多（p < 0.05）。
