Surface Gloss, Radiopacity and Shear Bond Strength of Contemporary Universal Composite Resins

The surface gloss, radiopacity and enamel/dentin shear bond strengths (SBS)s of five commercially available contemporary universal composite resins (CR)s were examined. tested CRs as follows: G-aenial A’CHORD (GA), Charisma Diamond (CD), Neo SpectraTMST(NS), Filtek(F) Estelite Asteria(EA). Twelve cylindrical specimens per group fabricated gloss measurements performed using a meter after polishing darkening. Five each radiographed CMOS sensor alongside an aluminum stepwedge, human enamel dentin. mean gray values measured with computer program. A total 120 bonded dentin subjected to SBS test. To analyze we used Kruskall–Wallis, Wilcoxon signed rank, Welch tests one-way ANOVA. Games–Howell, Tukey’s HSD tests, Dunn’s multiple comparisons for (p < 0.05). In terms units the materials darkening, highest was achieved GA, followed by NS, F, CD EA 0.001). All showed significantly higher in comparison NS presented values, while other were, decreasing order; GA ranking varied dentin, adhesive failure detected at rate. Commercially display different properties.
