Abstract

Aim: This study evaluated and compared the role of newer dental adhesives to bond composite resin to the resin modified glass ionomer (RMGIC) liner.

Materials and methods: Thirty-six specimens were prepared on acrylic blocks, with wells prepared in it by drilling holes, to retain the RMGIC. The specimens were randomly divided into three groups of 12 specimens each. In group I, a thin layer of an adhesive, which was a Total-etch type (Adper Single bond-2), was applied between RMGIC and the composite resin. Ingroup II, a Self-Etch adhesive (Adper prompt-L pop) was applied, and in group III there was no application of any adhesive between RMGIC and the composite resin. After curing all the specimens, the shear bond strength was measured using an Instron universal testing machine.

Results: The results were drawn and tabulated using ANOVA-fishers and Tukey's statistical tests. The maximum shear bond strength values were recorded in group II specimens with the self-etch adhesive (Adper prompt-L pop), showing a mean value of 5.826 when compared to the group I adhesive-Total-etch type with a mean shear bond strength of 4.6380, while group III specimens, where no adhesive was used, showed a minimum mean shear bond strength of 2.8385. There was a great and significant difference between group I and group II (P value 0.003), whereas, both group I and group II showed a vast and significant difference from group III (P value 0 - 001).

Conclusion: Hence, this present study concludes that application of Self-Etch adhesive (Adper prompt-L pop) in between RMGIC and composite resin increases the shear bond strength between RMGIC and the resin composites, as compared to the Total-etch type adhesives (Adper Single Bond 2), as well as, without application of the adhesive agent.

Keywords: Sandwich technique; Self-Etch adhesive; Total-etch adhesive.
