Resumo

ObjectiveTo evaluate the clinical performance of posterior resin composite restorations regarding experimental and regular adhesive protocols in caries affected-dentin (CAD).Material and methodsA total of 92 class I and class II cavities with carious lesions were selected and randomly assigned to the following groups: (1) bioactive glass-ceramic powder/two-step etch and rinse system, (2) control/two-step etch and rinse system, (3) bioactive glass-ceramic powder/two-step self-etching system, and (4) control/two-step self-etching system. Two operators carried out the adhesive protocols and restored the cavities with a nano-hybrid resin composite. Participants were followed up at 1week and 6, 12, and 18months for clinical evaluation performed by two blinded examiners and calibrated according to FDI criteria. Data were analyzed using Kruskal-Wallis and Dunn tests with a confidence of 95%.ResultsThe clinical performance of resin composite restoration was not affected by the experimental use of an adhesive protocol including a bioactive glass-ceramic powder for 18months post-procedure. However, there was a significant difference between group 2 and group 4 (p<0.05) for marginal adaptation (18months). Group 2 was significantly different from group 3 (p<0.05) for fracture of material/retention (18months) and marginal adaptation (1week); group 2 showed a better performance.ConclusionAdhesive protocols can alter the clinical performance of posterior restorations in terms of marginal adaptation and the fracture of material/retention in CAD. Clinical significance: Adhesive protocols may influence the success of resin composite restorations in CAD; this is important because failure can lead to caries, re-incidence, and/or clinical re-work.
