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 .
Effect of glass-ionomer cement lining on postoperative sensitivity in occlusal cavities restored with resin composite--a randomized clinical trial.
This study investigated the ability of a glass-ionomer cement ( GIC ) lining to reduce postoperative sensitivity in occlusal cavities restored with resin composite . In addition , the effects of a total-etch and self-etch adhesive on postoperative sensitivity were also compared . Patients who had moderate to deep occlusal caries of at least one molar were recruited . Overall , 103 restorations were placed in 70 participants , with an average age of 22.8 + /- 3.8 years . Preoperatively , each tooth was evaluated for cold-stimulated tooth sensitivity using a visual analog scale . If present , tooth sensitivity induced by cold/hot drinks or occlusal function was also noted . Caries was stained with a caries detector dye , then removed using slow-speed burs and h and excavators . The cavity was restored with one of four r and omly allocated restorative procedures : 1 ) bonded with a two-step , total-etch adhesive ( Single Bond 2 ) ; 2 ) lined with a resin-modified GIC liner ( Fuji Lining LC ) , then bonded with total-etch adhesive ; 3 ) bonded with a two-step , self-etch adhesive ( Clearfil SE Bond ) and 4 ) lined with the GIC liner , then bonded with self-etch adhesive . The cavities were incrementally filled with a nanofilled hybrid resin composite . At recall , postoperative sensitivity was evaluated at one week and one month . Overall , postoperative sensitivity in daily function was rare . No significant difference in postoperative sensitivity , either in daily function or in response to a cold stimulus , was observed between the restorative procedures with or without the GIC liner , regardless of the adhesive used ( p > 0.05 ) . In addition , no difference in postoperative sensitivity was noted between use of the self-etch and total-etch adhesive
No overall effect was revealed in the meta-analyses , meaning that no influence of the  ER or SE strategy on POS .
