The purpose of this study was to test the effectiveness of a universal bonding agent (Prisma Universal Bond) when used in dentine cavities. The measurement of marginal contraction gaps was the basis for determining the effectiveness of this bonding agent. The use of the bonding agent led to a significant reduction in restoration marginal gaps. Thermocycling of restorations with the bonding agent resulted in a widening of the marginal gaps though this was not significant. It was interesting to note that some thermocycled restorations showed no marginal gaps.
本研究的目的是测试一种通用粘结剂(Prisma Universal Bond)用于牙本质龋洞时的有效性。边缘收缩间隙的测量是确定这种粘结剂有效性的依据。使用该粘结剂可显著减少修复体边缘间隙。粘结剂修复体的热循环导致边缘间隙增大,尽管这并不显著。值得注意的是,一些经过热循环的修复体未显示边缘间隙。
