ABSTRACT

Context: Mechanical properties such as compressive strength of core build up materials play an important role in efficacy and longevity of the tooth and its restoration. Since majority of the masticatory forces in the posterior region are of compressive nature, the compressive strength of the restorative material should be high enough to resist fracture. Aims: To compare the compressive strength of four different core build up materials Paracore, Luxacore Z Dual, Fluorocore and Multicore. Methods and Material: A total of 40 specimens divided into four groups, 10 of each material were fabricated and subjected the universal testing machine to determine the compressive strength of each. Readings were recorded in each group and compared using one factor analysis of variance (ANOVA) after ascertaining normality by Shapiro-Wilk’s test and homogeneity of variance between groups by Levene’s test and the significance of mean difference between the groups was done by Bonferronis’s post hoc test after adjusting for multiple contrasts. Analyses were performed on SPSS software (Windows version 17.0). The differences observed between the groups were statistically significant. Results: Group 1 namely Paracore showed the highest compressive strength than the rest of the groups. Conclusions: It was concluded that Paracore is the best suited material for core build up.
