Comparison of the Flexural Strength of Four Core Built up Materials

ABSTRACT

The aim of this study is to compare the flexural strength of 4 commonly used core build up materials in clinics. Four core built up materials, a cermet cement (ketac silver), a light cure composite, conventional silver amalgam (control group) and zirconomer (zirconia reinforced GIC) were used and were divided into Group A, B and C and D respectively. The root canal of 90 extracted mandibular molars with similar anatomy and morphology were selected. Highest flexural strength was shown by Group A followed by group C, group B and then group D.
