Aim and objective: To evaluate and compare the shear bond strength of the fifth, sixth, seventh, and eighth generations of bonding agents.
Methods and materials: Forty freshly extracted premolars were selected and assigned into five groups: group I—fifth-generation bonding agent (SwissTEC SL Bond), group II—sixth-generation bonding agent (One Coat), group III—seventh-generation bonding agent (One Coat 7.0), group IV—eighth-generation bonding agent (One Coat 7 Universal), and group V—control group. With the help of an air rotor, the coronal dentin was exposed. The dentin bonding agents were applied, which was then followed by the placement of composite on surface which was earlier exposed. Shear bond strength testing was then done using universal testing machine.
Statistical analysis: Data were analyzed using SPSS version 21. The intergroup comparison was done using one way analysis of variance along with post hoc Tukey\'s test.
Results: Maximum shear bond strength was found in the eighth generation of bonding agent followed by the fifth, seventh, and lastly, the sixth generation (p <0.05).
Conclusion: The greatest shear bond strength to dentin was seen in the eighth generation of dentin bonding agent with a great advantage of fewer steps involved in the procedure as compared to other generations of dentin bonding agents.
