Abstract

Objective: To compare the bond strength of seventh-generation bonding agent with dentin of different age groups.

Methods: Non-carious intact 55 teeth were grouped into five; Group A-16 to 20 years, Group B-21 to 30 years, Group C- 31 to 40 years, Group D- 41 to 50 years, Group E- 51 to 60 years. They were mounted on acrylic blocks and occlusal surface was prepared by sectioning it perpendicular to the long axis of the tooth. Composite build-up with seventh generation bonding agent was adapted and cured on the prepared occlusal surface. After thermocycling, the specimens sere tested using a universal testing machine to calculate the microtensile bond strength.

Results: The highest mean value was exhibited among Group E the highest (34.8182 ± 7.74362), and the mean value of group A; the lowest (21.1818 ± 5.23103) among all tested groups. ANOVA test was used to check the microtensile bond strength among groups and TUKEY POSTHOC was used to compare the tensile strength between groups.

Conclusion: The dentin of old age group demonstrated the highest bond strength.
