The purpose of this in-vitro study was to evaluate the marginal sealing ability of three adhesive systems on class V composite resin restorations. The adhesive systems that were employed in this study were Single bond (3M, total etch adhesive), Fuji bond LC (GC, glass ionomer based adhesive) Prompt L- Pop (3M, self etching adhesive). Standardized class V cavity preparations were made at the CEJ of 45 maxillary premolars. Micro fill composite resin (Kulzer. Charisma) restoration was placed, light cured tbr40 seconds, and polished. The surfaces around the restorations were coated with nail varnish, stained in Rhodamine-B fluorescent dye for 24 hours and longitudinally sectioned. Microleakage was evaluated with a fluorescent light microscope under I OX magnification. The teeth were scored on a ranking system of 0-4, where '0' means no leakage and '4' means leakage along or up to axial wall. All the results were statistically analyzed. The following conclusions were arrived that none of the bonding agents used in the study could completely prevent the microleakage and also among all the bonding agents tested, Prompt L- Pop exhibited the maximum microleakage at the composite dentin interface, followed by Single bond and Fuji bond LC. Fuji bond LC exhibited the least microleakage compared to both Prompt L-Pop and Single bond, although there was no statistical difference with Single bond. Among all the groups tested Fuji bond LC performed better.
