Comparative Evaluation of Shear Bond Strength of Fifth, Seventh, and Eighth-generation Bonding Agents in Permanent Teeth: An Study.

AIMS AND BACKGROUND

In achieving clinical success with adhesive materials, bond strength holds significant importance. The goal of testing the strength of the bond is to establish a value for how strong the binding of an adhesive system is to the dental structures. The aim of this study is to comparatively evaluate the shear bond strength of fifth, seventh, and eighth-generations of bonding agents.

MATERIALS AND METHODS

Forty-five extracted permanent teeth were allotted into three groups ( = 15), namely, group A: ADPER single bond 2, group B: single bond universal, group C: G-Premio bond. Etchant was applied to the exposed surface, and then adhesive was applied as stated in the manufacturer's instructions, followed by composite (Z350) buildup. The maximum shear force required to debond the specimen was recorded using a universal testing machine. One-way ANOVA test was utilized for statistical comparison at each assessment point, with the significance level set at < 0.05 using SPSS statistical tool.

RESULTS

The maximum shear bond strength was reported for group C, with the mean shear bond strengths of groups A, B, and C being 13.23, 9.66, and 19.21 MPa, respectively.

CONCLUSION

The newly introduced eighth-generation adhesive showed superior bond strength values compared to the fifth and seventh-generation bonding agents; this difference was statistically significant.
