Contraction patterns in cavities tested with two dentin bonding agents.

Differences in microleakage at occlusal and cervical margins have been attributed to variations in the microstructure of enamel. The lack of homogeneity in dentin may have similar influences on the effectiveness of composite bonding. This study examined marginal contraction gaps occurring at the occlusal, cervical, mesial, and distal margins of dentin cavities restored with a composite restorative material, with and without the use of dentin bonding agents. Results showed that marginal contraction gaps at the dentin-restoration interface among the four sites in both treated and untreated cavities are not statistically different in size. Adhesion of composite restorative materials to dentin is not affected by the location of the margins.

Influence of preparation site on the effectiveness of two dentine adhesives.

There are morphologic and chemical variations in dentine in different parts of a single tooth. The aim of this study was to ascertain whether the site of restoration cavities was related to marginal contraction gaps at the restoration/dentine interface. The results showed no significant relationship when using a commercially available dentine adhesive. However, when an experimental dentine adhesive was used, there was a significant difference in the size of the marginal contraction gaps on the buccal and lingual surfaces of restorations.

Effectiveness of a universal adhesive on dentine--an in-vitro study.

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.
