Abstract

This study was performed to investigate the effect of temporary sealing with cement on the tensile bond strength of resin luting cement to tooth substrate. Five temporary cements and five resin luting cements were used. Six hundred bovine incisor teeth were randomly divided between each group. Effect of temporary sealing on the tensile bond strength of resin luting cement varied in accordance with the temporary cement used. Temporary sealing with both the eugenol-containing and the eugenol-free temporary cements decreased the tensile bond strength of resin luting cement. The tensile bond strength with one of the resin luting cements was most stable on both enamel and dentin pretreated with all temporary cements tested.

摘要

本研究旨在探讨用粘固剂进行临时封闭对树脂粘结水门汀与牙齿基质之间拉伸粘结强度的影响。使用了五种临时粘固剂和五种树脂粘结水门汀。每组随机分配120颗牛切牙。临时封闭对树脂粘结水门汀拉伸粘结强度的影响因所使用的临时粘固剂而异。含丁香酚和不含丁香酚的临时粘固剂进行临时封闭均会降低树脂粘结水门汀的拉伸粘结强度。在所测试的所有临时粘固剂预处理的牙釉质和牙本质上，其中一种树脂粘结水门汀的拉伸粘结强度最为稳定。
