Indirect Resin Composite Inlays Cemented With a Self-adhesive, Self-etch or a Conventional Resin Cement

13. april 2021 opdateret af: Mansoura University

Indirect Resin Composite Inlays Cemented With Three Different Luting Strategies

The present study was designed to provide further evidence in this particular research prospective, and this study hence aimed to clinically evaluate the 5-years adhesion durability of indirect resin composite inlays luted with three different resin cement strategies in MOD Class II restorations. The formulated null hypothesis was that there is no significant difference in the clinical performances of the three different resin cement strategies for luting indirect resin composite inlays in MOD Class II restorations for 5-years.

The research question was as follows: Do self-adhesive resin cements in class II restorations present better clinical performances than conventional etch-and-rinse and self-etch resin cements according to the USPHS criteria?

Detaljeret beskrivelse

Objective: To clinically evaluate the 5 years adhesion durability of indirect resin composite inlays luted with three different resin cement strategies in MOD Class II restorations.

Materials and Methods: A randomized clinical trial was conducted following the protocol, 40 patients with three large cavities for each one that indicated for indirect MOD Class II restorations were enrolled in the current study. Then, 120 indirect resin composite inlay restorations (SR Nexco) were placed and luted with three different resin cement strategies; an etch-and-rinse (Variolink N), self-etch (Panavia F2.0) and self-adhesive (RelyX Unicem). Each resin cement was used for luting 20 inlay restorations. A single operator placed all restorations according to the manufacturer's instructions. Immediatelly after placement, the restorations were finished and polished. Clinical evaluation was performed at baseline and at 1, 3 and 5 years intervals after placement by two independent examiners using modified USPHS criteria. The changes in the USPHS parameters during the 5 years period were analyzed with Fredman test. The baseline scores were compared with those at the recall visits using Wilcoxon signed rank test, where the level of significance was set at p˂0.05.
