Immediate Clinical Performance Dual-Cure Bulk-Fill Posterior Composite
Objectives: Evaluate clinical performance in proximal or occlusal restorations with dual-cure Bulk- Fill and nanofilled composite by Ryge criteria.
Methods: 30 voluntary patients with 2 proximal or occlusal caries lesions in posterior teeth. The depths of the lesions were ≥ 4.0mm with antagonist teeth. They were distributed randomly: Group FU: 30 Fill-Up resins Bulk-fill-Brilliant Everglow (Coltene-Whaladent) and Group Z350: 30 restorations Filtek Z350 (3M-Espe). The restorative procedure was performed with anesthesia and absolute isolation. All cavities were conditioned in enamel for 20 seconds with 37% phosphoric acid and then rinsed and dried. Single Bond Universal adhesive (3M-Espe) was applied for Z350, One Coat 7 Universal in the cavities of the FU (Ivoclar-Vivadent), according to manufacturer’s instructions. The FU restorations were done with an only layer (≥4mm) and a final layer with Brilliant Everglow. Z350 were restored with 2 mm deep multilayer. Restorations were polymerized for 30 seconds with a Bluephase light-curing unit (Ivoclar-Vivadent) with an intensity of 1.100mW/cm2. Calibrated operator (Kappa>0.8) evaluated the restorations by Ryge criteria; marginal staining (MS) and adaptation (AM), anatomy (A), postoperative sensibility (S) and caries (C) two weeks later. The Kruskal Wallis test was used for the statistical analysis of the information software SPSS 22.0 (95 %of significance).
Results: For follow-up 30 patients were evaluated (N(total)=60). Were evaluated alpha for AM: 100% Z350 and 97,8 % for FU; MS, A,S and C there were 100% for both groups. There were not significant differences between the groups (p >0.05).
Conclusions: For the two occlusal-proximal composites there were not significant differences in the immediate clinical performance evaluated by Ryge criteria.
