BULK-FILL COMPOSITES WITH ADHESIVE UNIVERSAL ENAMEL SELF-ETCH MODE. PRELIMINARY STUDY.
Objectives: Compare the immediate clinical performance in posterior restorations with two Bulk- Fill composites performed with universal adhesive in total self-etch strategy.
Methods: 60 restorations were performed in 20 patients with at least 3 occlusal or proximal caries lesions in posterior teeth. The depths of the lesions were between 2.5mm-4.0mm and with antagonist and proximal teeth. The groups were distributed randomly: Group T: 20 restorations Tetric N-Ceram Bulkfill (Ivoclar-Vivadent), Group F: 20 restorations Filtek Bulkfill (3M-Espe) and Group control Z350: 20 restorations Filtek Z350 (3M-Espe). The restorative procedure was done with anesthesia and absolute isolation. Z350 were conditioned in enamel for 20 seconds with 37% phosphoric acid and then rinsed, dried and applied adhesive Single Bond Universal (3M-Espe). Group T was applied adhesive AdheSE Bond Universal (Ivoclar-Vivadent) according to manufacturer’s instructions without enamel etching and group F was applied adhesive Single Bond Universal according to manufacturer’s instructions without enamel etching. The T and F restorations were done with an only layer (maximum deep of 4 mm) and Z350 were restored with 2 mm deep multilayer. Restorations were polymerized for 30 seconds with a Bluephase N light-curing unit (Ivoclar-Vivadent) with intensity of 1.100mW/cm2. Calibrated operator (Kappa>0.8) evaluated the restorations by FDI criteria: marginal staining (MS) and marginal adaptation (MA), fracture and retention (FR), surface luster (SL), anatomy (A), contact point (CP), color (C) and postoperative sensibility (PS) two weeks later. The Kruskal Wallis test was used for the statistical analysis of the information software SPSS 22.0 (95% level of significance).
Results: For follow-up 20 patients were evaluated (N=60). For the three groups all parameters were evaluated alpha. There were not significant differences between the groups (p>0.05).
Conclusions: For the two bulk-fill and group control composite-resin restorations there were not significant differences in the immediate performance according to FDI criteria.
