Tensile bond strength of four resin luting agents bonded to bovine enamel and dentin.

Statement Of Problem: The resistance to fracture of ceramic restorations depends on adequate bonding to tooth structure. The dental substrate and the types of resin luting agents used are believed to produce variability in adhesive properties.

Purpose: The purpose of this study was to evaluate the tensile bond strength of 4 resin luting agents to bovine enamel and dentin.

Microleakage in ceramic inlays luted with different resin cements.

Purpose: The objective of this in vitro study was to evaluate the microleakage in ceramic inlays using different resin cements with margins in enamel and cementum/dentin interfaces.

Materials And Methods: Standard Class II MOD inlay cavities were prepared in 32 noncarious human premolars. The cavities were randomly divided into 4 groups (n = 8):

Control Group: cavities were treated with Single Bond and incrementally filled with a composite resin (P60); Enforce group: feldspathic ceramic inlays were luted using Prime & Bond 2.
