No overall effect was revealed in the meta-analyses , meaning that no influence of the  ER or SE strategy on POS .
SIGNIFICANCE The type of adhesive strategy ( ER or SE ) for posterior resin composite restorations does not influence the risk and intensity of POS .
OBJECTIVES A systematic review and meta- analysis were performed on the risk and intensity of postoperative sensitivity ( POS ) in posterior resin composite restorations bonded with self-etch ( SE ) and etch- and -rinse ( ER ) adhesives .
The Cochrane Collaboration’s tool for assessing risk of bias in randomised trials
Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more
