Abstract

Aim: The aim of this study was to evaluate and compare the fracture resistance of ParaCore, luxacore, multicore in permanent anterior teeth 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 – Multicore, Group B – Luxacore, Group C – Paracore, and Group D – control group, without any core buid up), 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 fracture resistance followed by Group B and then group C. The least strength exhibited was by Group D – Control group preceded by Group A – ParaCore.
Conclusion: MultiCore showed the highest fracture resistance followed by Luxacore, ParaCore, and control group
 

Keywords: Fracture resistance, Paracore, Muticore luxacore
