Aggarwal V, et al. - Experts assessed the impact of the application of calcium silicate materials (CSMs), after acid etching, on the longevity of the hybrid layer and marginal adaptation of composite restorations. They conducted statistical analysis with two-way analysis of variance with Holm-Sidak's correction for multiple comparisons. Findings suggested a probability of the application of CSMs after acid etching to be a potential avenue in preserving the resin-dentin bonds. The marginal adaptation values in both adhesive groups were improved by the application of CSMs.
