Purpose: The study was conducted with the aim of comparing the shear bond strength (SBS) and microleakage of Tetric N-Bond, G-bond, and Xeno V (seventh generation dentin adhesives) in primary anterior teeth. Materials and Methods: For the shear bond strength, 45 teeth were randomly divided in to three groups namely group A, B, C (n = 15). Samples were mounted horizontally on acrylic block exposing the facial surface and bonded with different adhesives according to manufacturer instructions. A split Teflon mold was used to build the composite resin cylinder and light cured. Shear bond strength was tested using a universal testing machine. The values were statistically analysed. For microleakage, another 45 teeth were similarly grouped. Two class V cavities were prepared on the labial surface and treated with different dentine bonding agents and restored with resin composite (Ivoclar vivadent) A2 shade. The restorations were subsequently thermally stressed for 200 cycles and were subjected to dye penetration test, followed by sectioning through the center of the restoration labiolingually. Each section was examined using stereomicroscope at × 40 magnification to asses dye penetration at the margins of the restoration. Results: The SBS varied between 22.12-23.77 N/mm 2 (P-value = 0.231). The microleakage scores varied between 0.6-1.2 (P-value = 0.03; Post-hoc test A vs B (0.007)).There was a statistically higher degree of microleakage observed in group A when compared to group B. Conclusion: Among the three commercially available bonding agents, there were no statistically significant differences in SBS. G bond had higher microleakage when compared to the others.
