A clinical and scanning electron microscope study was carried out of investigate the effectiveness of SCOTCHBOND and DENTIN ADHESIT bonding agents for retention and adaptation of composite resin in C1. V. restorations. Clinical study comprised of 120 restorations and SEM study comprised of 64 restorations. The teeth were divided into four groups namely A,B,C and D. SCOTCHBOND was used with acid etch technique in Group A and it was used with non acid etch technique in Group B . While DENTIN ADHESIT was used in acid etch technique in Group C and it was used in non acid etch technique in Group D. SCOTCHBOND showed better results when compared with DENTIN ADHESIT in clinical study. In in-vitro study, SCOTCHBOND gave better adaptation to cavity margins at different at different levels of enamel, dentin and D.E. Junction compared to DENTIN ADHESIT. Overall result was in favour of acid etch technique in both the studies.
