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 .
Clinical evaluation of two "packable" posterior composite resins
Abstract .The purpose of this study was to evaluate the clinical performance of two " packable " posterior composites : Prodigy Condensable ( P ) ( Kerr ) and Definite ( D ) ( Degussa ) .  Thirty-six patients participated in the study . A total of 78 restorations were made , 40 with D and 38 with  P.  Each patient received at least two restorations  , one of each studied material . The material s were h and led according to the manufacturer 's instructions . The restorations were finished and polished after 1 week . They were evaluated at baseline and after 1 year by two independent evaluators using the United States Public Health Service ( USPHS ) criteria . Colored slides were made of all the restorations . After 1 year , 35 patients and 76 restorations ( 39 with D and 37 with P ) were available for evaluation . All restorations received A criteria except the following ones , which received B criteria : color P ( one restoration ) and D ( one restoration ) , marginal staining P ( three restorations ) and D ( two restorations ) , surface staining P ( nine restorations ) and D ( three restorations ) , anatomic form P ( one restoration ) and D ( three restorations ) , and marginal adaptation P ( one restoration ) and D ( eight restorations ) . The obtained data were tabulated and statistically analyzed using the Fisher and McNemar tests . After 1 year , P showed a significant increase in superficial staining . For D , the marginal adaptation became significantly worse than baseline and P. The studied material s can be considered acceptable during this evaluation period . Further evaluations are necessary for a better clinical performance analysis
