This in vitro study was carried out to evaluate the quality of Resin - Dentin Interface and also to determine the shear bond strength of three different bonding systems. The systems used was Gluma Comfort Bond, Adhese and Prompt. L. Pop.
The Resin - Dentin Interface was evaluated under scanning electron microscope, which showed variation in hybridization and resin tag formation between the groups. The specimens were also subjected to shear bond strength in universal testing machine. The mean bond strength of Gluma Comfort Bond (Group 1) = 18.81 MPa, Adhese (Group 2) = 23 MPa and Prompt L Pop (Group 3) = 10.83 MPa. The results were statistically analyzed using Anova and Students-t- test. 11 was found that the bond strength value of group 2 were significantly higher than group 1 and group 3.
The present study concludes that it is the uniformity and density of the hybrid layer which is more important than the thickness for the integrity of the restorative - tooth interface. |
