Introduction: It is presumed that self- etch adhesives are prevent post operative sensitivity in posterior restorations. In this study author tested a hypothesis: a self etch adhesives would results in postoperative sensitivity than etch and rinse. Methods patients were recruited on the basis of class I and class II restorations in molars and premolars. The author placed 60 restorations with self etch adhesive [Adper Easy Bond, 3M ESPE, Germany] and 72 restorations with Tetric N-Bond [Ivoclar-Vivadent, India], which uses 34% phosphoric acid to etch enamel and dentine simultaneously. Cavity preparations were of established design for composite restoration, with no beveling on occlusal surface with supported enamel margins. Restoration done with corresponding composite materials under rubber dam isolations. The restored teeth were evaluated preoperatively and a 15 days, 2 months and 6 months postoperatively for sensitivity to cold [ice], air and masticatory forces. Results analysis of variance reveled no statically significant difference in postoperative sensitivity between the self etch and etch and rinse at any recall time. Conclusion of study was that the self adhesive did not differ from the etch and rinse in terms of sensitivity.
