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 ? ”
Influence of Adhesive Type and Placement Technique on Postoperative Sensitivity in Posterior Composite Restorations.
PURPOSE This double blind , r and omized clinical trial compared the postoperative sensitivity of the placement technique ( incremental and bulk fill ) in posterior composite resin restorations bonded with two different adhesive strategies ( self-etch and etch- and -rinse ) . METHODS Posterior dental cavities of 72 participants ( n=236 ) , with a cavity depth of at least 3 mm , were r and omly divided into four groups . The restorations were bonded using either the etch- and -rinse Tetric N-Bond ( Ivoclar Vivadent ) or the self-etch Tetric N-Bond SE ( Ivoclar Vivadent ) . The composite resin Tetric N-Ceram Bulk Fill ( Ivoclar Vivadent ) was placed either incrementally or using the bulk-fill technique . Two experienced and calibrated examiners evaluated the restorations using World Dental Federation criteria after one week of clinical service . Spontaneous postoperative sensitivity was assessed using a 0 - 4 numerical rating scale and a 0 - 10 and 0 - 100 visual analog scale up to 48 h after the restorative procedure and after one week . RESULTS The risk ( p>0.49 ) and intensity of spontaneous postoperative sensitivity ( p>0.38 ) was not affected by the adhesive strategy or the filling technique . The overall risk of postoperative sensitivity was 20.3 % ( 95 % confidence interval 15.7 - 25.9 ) and typically occurred within 48 hours after the restorative procedure . CONCLUSIONS The overall risk of immediate postoperative sensitivity was 20.3 % and was not affected by either the adhesive strategy ( etch- and -rinse/self-etch ) or the filling technique ( incremental/ bulk )
