Comparative Evaluation Of Shear Bond Strength Of Biodentine And Resin Modified Glass Ionomer Cement Using Two Adhesive Systems In Premolars Restored With Composites: An In – Vitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 4
Abstract
Introduction: The success of the restoration depends on the proper bonding of the restorative material to the prepared cavity in order to provide pulp protection and achieving adequate seal. This was met with the introduction of new materials like resin modified glass ionomer cement (RMGIC) and Biodentine. The development of the adhesive agents for bonding of restorative material has rapidly evolved in recent years, which will increase the bonding between the RMGIC and Biodentine to the composite resin. Aim: To evaluate and compare shear bond strength of tricalcium silicate-based restorative material and resin modified glass ionomer cement in premolars using two adhesive systems. Materials and Methods: Occlusal surface of crowns were ground flat. A cavity with 6mmX2mm is prepared over the flat surface and filled with biodentine and RMGIC according to the groups ascertained (Group A – Biodentine, Group B – RMGIC). It is then further subdivided into two subgroups (Group A1, B1 – total etch adhesive system and Group A2, B2 – self etch adhesive system). After the application of adhesives PVC molds were stabilized over filled cavity and it is restored with composite resin. Shear bond strength is evaluated using Universal Testing Machine. Results: Results showed that biodentine with adper single bond had a mean value of 12.488 and resin modified glass ionomer cement with universal bond had a mean value of 12.191, resin modified glass ionomer cement with adper single bond had a mean value of 9.507, biodentine with universal bond had a mean value of 7.283. On comparison within the groups, group A1 - Biodentine with Adper single bond showed better shear bond strength than with group A2 - Universal bond which was statistically significant (P = 0.03). On comparing between the groups, group B2 - RMGIC with Universal bond had a higher shear bond strength than group A2 - Biodentine which was statistically significant (P = 0.04). Conclusion: Group A1 – Biodentine with Adper single bond (total etch system) shows better shearbond strength which is followed by group B2 - RMGIC with Universal bond (self etch system) and group B1 - RMGIC with Adper single bond and then group A2 - Biodentine with Universal bond.
