RESUMEN
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.
RESUMEN
The purpose of this systematic review was to evaluate clinical performance of flowable composite in carious and noncarious lesions. An electronic search was conducted using specific databases (PubMed, Embase, Cochrane Library, and LILACS) through March 2017. Clinical trials for restoration of carious and noncarious lesions were included with no date restrictions; follow-up was 6 months at least and dental restorations were evaluated using the United States Public Health Service criteria. The systematic search generated 908 papers, of which 35 papers were included for full-text review. Inclusion criteria were met by eight papers, six papers were for noncarious lesions and two papers were for restoration of carious lesions. The results of this review have shown no statistical or clinical difference between flowable and conventional composites for all tested outcomes in both carious and noncarious lesions. Both materials have shown clinically acceptable scores for all criteria, with no evidence of clinically unacceptable scores except in retention, with a retention rate of 83% in both materials after 36 months. Flowable composites had clinical efficacy after 3 years of service similar to that of conventional composite in both carious and noncarious lesions, these results are based on low quality of evidence. Based on the available literature and the best available evidence, flowable composites can be used in restoration of noncarious cervical lesions and minimally invasive occlusal cavities.
