To Compare and Evaluate the Shear Bond Strength of Sixth- and Seventh-generation Bonding Agents.

AIM

To compare and evaluate the shear bond strength of sixth and seventh-generation dentin bonding agents.

MATERIALS AND METHODS

Around 75 extracted permanent mandibular premolars were selected and assigned into two groups. The samples were cleaned, cavities were prepared, and the bonding agent was applied and stored in distilled water for 24 hours. Shear bond strength testing was done using a universal testing machine at the crosshead speed of 1 mm/minute. Data were analyzed statistically by one-way analysis of variance (ANOVA) and paired test.

RESULTS

The greatest mean shear bond strength to dentin was exhibited by the sixth-generation dentin bonding agent due to the solvent present, which has a low concentration and low hydrophilicity than the seventh-generation.

CONCLUSION

Sixth-generation adhesives showed significantly higher mean shear bond strength to dentin than seventh-generation adhesives.

CLINICAL SIGNIFICANCE

Bond strength values are gross assessing tools for evaluating the efficacy of restorative bonding materials to dentin. And as the shear bond strength is less technique sensitive to perform, it will highlight the strength at the bonded interface.
