抄録

In an attempt to evaluate the consistency of resin-dentin bonds, Shono (1999) have developed a new version of microtensile bond test method that permit evaluating regional tensile bond strength across entire bonded surfaces. In this studies, the new version of microtensile bond test was used to evaluate the regional bond strengths of six commercially available dentin bonding systems to dentin. The purpose of this study was to test the hypothese that there is no regional difference in the dentin bond strength.<BR>As the results, the commercially available adhesive resins bonded well to dentin but compared to the control group of resin bonded to resin specimens there have a widely standard deviation. Almost the failures were classified as adhesive in nature by using the new version of microtensile test method. There have a tendency that wet bonding system shown higher microtensile dentin bond strength than that of self-etching system. The results obtained in this study require rejection of the hypothese that there was no regional difference in the dentin bond strength. The newly developed test method is very useful for evaluating regional tensile bond strength tests across entire bonded surfaces. This type of information is much more meaningful than the single measurements made with conventional resin composite bond strength tests.
