NCT04848987

Brief Summary

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?

Outcome Measures

Primary Outcomes (1)

  • Percentage % of patients with marginal staining

    Percentage of marginal staining in patients was clinically assessed using USPHS criteria. Restorations were given the score Alpha for the ideal clinical situation, Bravo for clinically acceptable and Charlie for clinically unacceptable and in need for replacement.

    5 years after restoration procedure

Study Arms (3)

Etch-and-rinse (Variolink N) resin cement

ACTIVE COMPARATOR

For etch-and-rinse resin cement, 40 inlays were cemented by Variolink N resin cement.

Procedure: Etching

Self-etch (Panavia F2.0) resin cement

PLACEBO COMPARATOR

Regarding self-etch resin cement, 40 inlays were cemented by Panavia F2.0 resin cement.

Procedure: Etching

Self-adhesive (RelyX Unicem) resin cement

NO INTERVENTION

For self-adhesive resin cement, 40 inlays were cemented by RelyX Unicem resin cement.
