Background: Adaptation of dental restorative materials to the walls of the cavity and the retentive ability of a material to seal the cavity against microleakage is one of the significant factor which attributes in success of restoration .Microleakage may be defined as the passage of bacteria, fluids, molecules or ions between a cavity wall and the restorative material applied to it. The present study is undertaken to evaluate and compare the sealing ability of three commercially available restorative materials (EQUIA Forte, Cention N, Glass Ionomer cement). Materials and Methods: Standard class V cavities of size 3 mm x 2 mm x 2 mm were prepared on a total of 30 caries free extracted teeth and restored with the Conventional Glass Ionomer, EQUIA Forte and Cention N according to manufacturer's instructions. After thermocycling, teeth were immersed in 0.5% methylene blue dye for 24 h. They were then sectioned buccolingually. Microleakage was assessed for the occlusal and gingival walls and evaluated for microleakage using a stereomicroscope. Results: Mean microleakage for conventional GIC (3.7) was the highest of all and it was least for Cention N (0.3). Conclusion: Cention N displayed the least microleakage and came to be better than the Equia Forte and Conventional Glass Ionomer Cement. Keywords: Cention N, EQUIA Forte, Microleakage.
