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 andMethods: In a split mouth design, after cavity preparation, 18 patients with conservative Class I cavities received randomly two pairs of restorations, either Vertise{u2122} flow or Filtek{u2122} Z350 XT Flowable combined with Scotchbond{u2122} Universal Etchant and Single Bond Universal, all materials were applied according to the manufacturer{u2019}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 {u2264} 0.05wasconsideredstatistically significant.Results: At baseline and 6 months, there was no statistically significant difference between both materials for all tested outcomes
