A comparative evaluation of shear bond strength of three different restorative materials to biodentine and TheraCal lc: An in-vitro study
AUTHOR(S): Dr. Bhavika Jain and Dr. Amita Tiku
The aim of this study was to evaluate and compare the shear bond strength of three different restorative materials to Biodentine and TheraCal LC respectively.
Materials and Methods: 60 acrylic blocks were prepared and divided into 2 groups of 30 samples each. Group I samples were filled with Biodentine and Group II with TheraCal LC. Each of these groups were further divided into 3 groups of 10 samples each in which restorative materials were packed over the Biodentine or TheraCal LC base as follows: Group IA- Biodentine-Composite, Group IIA- TheraCal LC-Composite, Group IB- Biodentine-Glass ionomer cement, Group IIB- TheraCal LC- Glass ionomer cement, Group IC- Biodentine- Resin modified GIC and Group IIC- TheraCal LC- Resin modified GIC. The samples were then tested for shear bond strength using the universal testing machine. The data were analysed using ANOVA test followed by Post hoc dunnett’s test for multiple group comparison.
Results: On comparison of shear bond strength, statistically significant difference (p<0.05) was found between Group IA and IIA and that of Group IC and IIC. No statistical significant difference (p>0.05) was present between Group IB and IIB. A highly statistical significant difference (p<0.001) was present between the six groups in relation to shear bond strength. Conclusion: The highest shear bond strength value was obtained with TheraCal LC and Composite and lowest value with Biodentine and GlC.
