Recognizing the need to develop new and improved dental adhesives and new long-lasting restorative materials, this proposal requests funds to establish an interdisciplinary materials science program project. The goals for the program project include: develop adhesives that will protect exposed dentin and the underlying pulp; assess the mechanical, physical, and biocompatibility properties of the newly developed adhesives and composite materials; develop and apply surface analysis techniques and promote collaboration between basic scientists. In order to accomplish these goals, over thirty scientists from the University of Missouri/Kansas City, Midwest Research Institute, and Surfaces Research and Applications have joined together as investigators. In addition, outside scientific experts will serve as technical advisors and will provide an interface with the scientific community and dental industry. The administrative scientific support personnel will consist of a director and co-director; administrative personnel; an internal review board; academicians who will provide academic support as research mentors; statistical support consultants and outside scientific consultants. The administrative support service also consists of three core activities which provide testing service for the subprojects. Statistical support, surface analysis and biocompatibility testing are included in the core activities. Three currently funded subprojects and three new proposed subprojects will constitute the major research effort. The four new subprojects will include the development of copolymer dental adhesive systems, development of improved coatings for composite fillers, development and application of surface analysis techniques, and biocompatibility test development and performance. Currently funded research includes characterization of dentin as a substrate for adhesion, development of nonshrinking matrix polymers, and investigation of multifunctional monomer adhesives. Through the combination of these efforts major goals of the program project should be accomplished, and the dental profession should benefit through the development of new biomaterials.

认识到需要开发新的和改进的牙科粘合剂和新的 长效修复材料，这项提案要求资金 建立一个跨学科的材料科学项目。这个 该计划项目的目标包括：开发能够保护 暴露的牙本质和潜在的牙髓；评估机械，物理， 以及新开发的粘合剂和生物相容性 复合材料；开发和应用表面分析技术和 促进基础科学家之间的合作。为了完成 这些目标，来自密苏里大学/堪萨斯大学的30多名科学家 城市，中西部研究所，表面研究和应用 已经联合起来作为调查人员。此外，外界的科学研究 专家将担任技术顾问，并将提供与 科学界和牙科行业。行政部门 科学支助人员将由一名主任和联席主任组成； 行政人员；内部审查委员会；将 作为研究导师提供学术支持；统计支持 顾问和外部科学顾问。行政支持 服务还包括三个提供测试的核心活动 为子项目提供服务。统计支持、表面分析和 生物兼容性测试包括在核心活动中。三 目前资助的次级项目和三个新的拟议次级项目将 构成了主要的研究努力。这四个新的子项目将 包括共聚牙科粘合剂系统的开发、开发 复合填料用改性涂料的研究、开发和应用 表面分析技术、生物兼容性测试开发和 性能。目前资助的研究包括牙本质的特征 作为粘合的衬底，开发非收缩基质聚合物， 以及多功能单体胶粘剂的研究。通过 这些努力的组合方案项目的主要目标应该是 完成了，牙科专业应该会通过 开发新的生物材料。
