Abstract

Aim: To evaluate the shear bond strength of Cention N and recent tooth-colored restorative materials to dentin.


Materials and Methods: Flat dentinal surface was prepared from 40 caries free, extracted human permanent molars and were mounted in acrylic rings. These were randomly divided into four groups–Group A: Ketac-Molar, Group B: Zirconomer Improved, Group C: Cention N, & Group D: GC Fuji ll LC (RMGIC).These restorative materials were applied on dentinal surface of all the specimens using Teflon molds. The mounted samples were stored in distilled water for 24 hours and thermocycled. They were then subjected to shear bond strength test using universal testing machine. Data was analyzed using a one-way analysis of variance (ANOVA) and Tukey`s post –hoc tests.


Results: Cention N exhibited highest mean Shear Bond strength (7.0487±0.42MPa).Ketac-Molar and Zirconomer Improved were comparable in their bond strength values (3.2157 ± 0.37,&3.4644 ± 1.18MPa), but depicted lower bond strength when compared to RM GIC (5.468 ±1.75MPa).


Conclusion: Cention N restorative material showed better bonding potential to dentin as compared to RMGIC, Zirconomer Improved and Ketac-Molar.
