EVALUATION OF A LOW SHRINKAGE RESIN BASED COMPOSITE IN CLASS I AND II CAVITIES

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。将低收缩复合树脂放置在I类和II类窝洞准备中，根据特定标准(直接和间接)在基线、3个月、1年和18个月评价树脂复合修复体；并评价树脂复合修复体的染色、边缘完整性、对冷的反应、放置时间和18个月的近距离接触，三年选项。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. To place a low shrink composite resin in Class I and Class II cavity preparations, evaluate the resin composite restorations at baseline, 3 months, 1 year, and 18 months for specific criteria (direct and indirect); and to evaluate the resin composite restorations for staining, marginal integrity, response to cold, placement time, and proximal contact for 18 months with a three year option.
