Abstract

 Aim: The aim of this study was to evaluate and compare the shear bond strength of ParaCore, FluoroCore, multicore, and resin modified 
glass-ionomer cement in mandibular premolar using universal testing machine. Materials and Methods: Eighty recently extracted intact 
caries free Human Permanent Mandibular Premolars and disinfected according to CDC guidelines on infection control in dental health-care 
setting 2003. The teeth were then randomly assigned to four groups on the basis of material used (Group A – ParaCore, Group B – FluoroCore, 
Group C – MultiCore, and Group D – Resin modified glass-ionomer cement), each group consisting of 20 samples. The dentin surface was 
treated with the respective adhesives of the groups and then bulk filled with core build-up materials. The attained samples were than subjected 
to shear loading in Instron Universal Testing Machine. The data were tabulated and statistically analyzed using analysis of variance, Tukey’s 
HSD test. Results: MultiCore material had the greatest shear force followed by Group B – FluoroCore. The least strength exhibited was by 
Group D – resin modified GIC preceded by Group A – ParaCore. Conclusion: MultiCore showed the highest shear bond strength followed 
by FluoroCore, ParaCore, and RMGIC.
