Abstract

Background:  Aim: To evaluate and compare tensile bond strength of sixth generation, seventh generation and eighth generation dentin bonding agents.  Method and Materials: Forty five freshly extracted caries free, unrestored human molars were selected. The occlusal surfaces were ground until flat and then they were divided into three groups. In Group A, sixth generation dentin bonding agent was applied onto the flat surface, likewise we applied, seventh generation and eighth generation in Group B and Group C respectively. All the samples were then restored with composite and evaluated for tensile bond strength test using universal testing machine. Statistical analysis: The data for this study was analysed using the ANOVA & Bonferroni statistical test. Results: Eighth generation dentin bonding agent (Group C) showed significantly higher value as compared to seventh generation (Group B) and sixth generation (Group A) dentin bonding agents. Conclusion: The mean tensile bond strength score was found to be maximum in eighth generation dentin bonding agent (Group C) followed by sixth generation (Group A) and was least in seventh generation (Group B) dentin bonding agent.

Keywords: Sixth, Seventh and Eighth generation bonding agents, Tensile bond strength.
