Mechanical properties such as flexural strength of core build up materials play an important role in efficacy and longevity of the tooth and its restoration.
To compare the flexural strength of four different core build up materials Paracore, Luxacore Z Dual, Fluorocore and Multicore.
A total of 100 specimens divided into four groups, 25 of each material were fabricated and subjected the universal testing machine to determine the flexural 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.
Group 1 namely Luxacore Z Dual showed the highest flexural strength than the rest of the groups.
It was concluded that Luxacore Z Dual is the best suited material for core build up in terms of flexural strength.
