Clinical evaluation of self-adhering flowable composite versus conventional flowable composite in conservative Class I cavities: Randomized controlled trial.

Abstract

Background:Self-adhering flowable composite (SAFC) minimized the time-consuming application procedures encountered with the traditional adhesive systems and restorative materials. Self-adhering composite combines the merits of both adhesive and restorative material technologies (8th generation) in a single product, bringing new horizons, and ambitions to restorative procedures.Aim:The aim of this study was to evaluate the clinical performance of SAFC compared to conventional flowable composite in conservative Class I cavities.Materials and Methods:In a split-mouth design, after cavity preparation, 18 patients with conservative Class I cavities received randomly two pairs of restorations, either Vertise™ flow or Filtek™ Z350 XT Flowable combined with Scotchbond™ Universal Etchant and Single Bond Universal, all materials were applied according to the manufacturer's instructions. Restorations were evaluated at baseline and after 6 months by two calibrated assessors using the modified United States Public Health Service criteria measuring (retention, postoperative hypersensitivity, color match, marginal adaptation, and marginal discoloration).Statistical Analysis:Chi-square test was used to compare between flowable composite materials after different follow-up periods, Wilcoxon signed-rank test was used to explore changes over follow-up periods. A value of P ≤ 0.05 was considered statistically significant. Results: At baseline and 6 months, there was no statistically significant difference between both materials for all tested outcomes.Conclusions:SAFC has shown clinical performance similar to conventional flowable composite after 6 months of clinical service.
