Abstract
In this present study there is no difference in postoperative sensitivity between a two-step etch-and-rinse adhesive and one-step self-etch adhesive strategies used under different placement techniques of composite resins to restore occlusal preparations in permanent molars.The clinical technique may play a more important role in postoperative sensitivity than the type of adhesive. The results of the present study are in line with a recent systematic review of the literature (Reis A et al., 2015),that systematic review concluded that the type of adhesive strategy used in bonding procedures in posterior composite resin restorations does not influence the risk and intensity of postoperative sensitivity immediately after the restorative procedure. The results of postoperative sensitivity in this study were in agreement with (Blanchard et al 2013) who concluded that the change in greatest sensitivity was associated with the type of dentin bonding agent used. This result was in favor with (Costa et al., 2017) (Ermis et al., 2009) (Cassetti and Martin 2006) (Jorge Perdigao et al., 2003) they stated that the clinical technique may be more relevant for the development of postoperative sensitivity than is the type of adhesive itself. Academic environment versus clinical practice setting: Finally, the limitations of the present study design; the present study was conducted in a university setting in which restorations are placed under ideal conditions to produce restorations as near perfect as possible, moisture control was usually done cotton rolls and saliva ejector, preventing contamination of the operative field
