Conclusions The present systematic review and meta- analysis indicate similar clinical performances of bulk-fill and conventional resin composites over a follow-up period of 12 to 72 months .
Clinical significance Based on the results of this study , the bulk-fill resin composites could be an alternative for direct restorations in posterior teeth .
Objectives The purpose of this systematic review was to compare the clinical performance of bulk-fill resin composites with conventional resin composites used for direct restorations of posterior teeth .
The research question was “ Do bulk-fill resin composites have a clinical performance comparable to conventional resin composites in posterior restorations ? ”
A prospective, randomized, double-blind clinical trial of one nano-hybrid and one high-viscosity bulk-fill composite restorative systems in class II cavities: 12 months results
Background : Recently , manufacturers have introduced bulk-fill composite resins that reportedly can be placed in increments of 4 mm or greater . Objective : The purpose of this article was to report the results of 12 months prospect i ve r and omized clinical trial that evaluated the clinical performance of one high-viscosity bulk-fill composite resin in Class II cavities of posterior teeth . Material s and Methods : Thirty-four participants had at least two Class II cavities included the study . Class II cavities restored with either a Tetric EvoCeram bulk-fi fill or universal nano-hybrid resin composite ( Tetric EvoCeram ) . A total of 74 restorations ( 37 with each material ) on 34 patients were placed according to the manufacturers ' instructions by one calibrated operator . Results : Seventy restorations were evaluated after 12 months evaluation period . No postoperative sensitivity , anatomic form , retention , and secondary caries were observed after 6 and 12 months . Regarding the items color match , marginal discoloration , and marginal adaptation , the statistical analysis did not detect any statistical significance between two material s ( P > 0.05 ) . Conclusion : After 12 months of clinical service , all restorations evaluated for both material s were classified as ideal , receiving predominantly Alfa scores for all parameters analyzed . Clinical Relevance : This study presents that high-viscosity bulk-fill resin composites ( RCs ) perform just as well as nano-hybrid RCs with the 2 mm RC layering technique , therefore could be alternative to conventional nano-hybrid RCs
