Abstract

Introduction: Because of ceramics' exceptional esthetical qualities, the range of materials for implicitly rebuilding missing tooth structures has already grown substantially in recent years. One of the earliest ceramics, silica-based ceramics, needs an adhesive attachment to the tooth structures to keep them from breaking. Previous studies looked at the relationship between the properties of human dentine and the shear bond strength of adhesive on a polished, flat tooth structure surface. For the cementation of inlays, Onlays, crowns, posts, and veneers, resin-based adhesive luting substances are often utilized. the self-adhesive qualities are based on phosphoric-acid methacrylates, which demineralize and penetrate the tooth substrate to provide micromechanical retention.

Methodology: This study was undertaken to investigate the shear bond strength between zirconia and two resin-luting types of cement. One is a conventionally used dual-cure resin cement and the other is a new universal self-adhesive self-cure resin cement. Methods: The two self-adhesive self-cured resin cement utilized in the current study, Panavia-F 2.0 and Rely X U 100 were two of these relatively novel products.

Result: The number of adhesive and cohesive fractures was calculated for both groups .chi-square test was applied to compare the two parameters in both groups. it was found that 60% of Group RelyX–U100 showed cohesive fractures and 13.33% of group Panavia–F2.0 showed cohesive fractures. There was a highly significant difference found in the type of fractures shown by each group.

Conclusion: It is thus concluded from the above study that to bond the zirconia restorations to dentin a better shear bond strength can be observed with respect to self-adhesive self-cure cement rather than the conventional dual resin cement where the application of primer & etchants is required for the bonding process.
