项目摘要

This project, undertaken to perform "Study on Biocompatible Adhesive Restorative Materials", was funded in part by a 3-year grant in aid from the Monbusho International Scientific Research Program.With an eye to developing new types of biocompatible and adhesive cavity liners and restorative materials, extensive research was undertaken as follows.A New Adhesive Cavity Liner-Microleakage Study in Class II Restorations-A new simplified adhesive restorative material-Shear bond strength and marginal microleakage tests-A New Light-activated Fluoride Releasing LinerA New Light-activated Fluoride Releasing Liner for Amalgam Restorations :A Microleakage StudyA new light-activated adhesive composite : shear bond strength and microleakageA new light-activated adhesive cavity liner : an in vitro bond strength and microleakage studyNew Adhesive Root Surface Restorative Material-An In Vitro Microleakage Study-Acidity of Light-activated Lining Cements and Removal of Dentin Smear LayerFluoride release from experimental cavity linerFluoride uptake into dentin from experimental cavity linerAcid resistance of the fluoride uptake dentin surfacePulpal response to a new light-activatedFluoride releasing linerPulpal response to a new light-activatedAdhesive filling materialBy the above-mentioned studies, it was clarified that the newly designed experimental light-cured adhesive cavity liners and restorative materials showed superior marginal leakage and shear-bond strength comparing with commercial products and that they showed high fluoride release, high fluoride uptake by dentin, the increase of dentin acid resistance and superior biocompatibility on animal experiments.The studies were already finished and presented on some scientific meeting, and some of them were already published on the scientific journals, but the remainder are in progress, to be published in the near future.

本项目由文部省国际科学研究计划资助，为期三年，旨在进行“生物相容性粘接修复材料的研究”。本项目着眼于开发新型生物相容性粘接型腔衬和修复材料，进行了以下广泛的研究：一种新的粘接剂腔衬-II类修复体中的微渗漏研究-一种新的简化的粘合修复材料-剪切粘结强度和边缘微渗漏测试-一种新的光激活氟化物释放衬里一种用于汞合金修复的新的光激活氟化物释放衬里：微渗漏研究一种新的光激活粘合复合材料：剪切粘结强度和微渗漏一种新的光激活粘合腔衬里：新型粘结性根面修复材料--微渗漏的体外研究--光的酸度实验性窝洞衬里的氟释放实验性窝洞衬里的氟吸收牙本质表面氟吸收牙本质表面的耐酸性牙髓对一种新的光激活的氟化物释放衬垫对一种新的光激活的粘合剂填充材料的牙髓反应通过上述研究，阐明了新设计的实验性光固化粘合剂洞衬和修复材料与商业产品相比显示出上级的边缘渗漏和剪切粘结强度，并且它们显示出高的氟化物释放，牙本质的高氟化物吸收，在动物实验中，牙本质抗酸能力增强，生物相容性上级。这些研究已经完成，并在一些科学会议上发表，其中一些已经发表在科学期刊上，但其余的正在进行中，将在不久的将来发表。
