Comparative Evaluation of Compressive Strength of Ketac Molar, Zirconomer, and Zirconomer Improved
Journal Title: Scholars Journal of Dental Sciences - Year 2017, Vol 4, Issue 6
Abstract
The ability of a dental restorative material to withstand occlusal forces is one of the major properties to be taken into consideration in restorative practice. Various materials are commercially available, exhibiting harmonious bonding to withstand better masticatory forces.The aim of this study was to evaluate and compare the compressive strength of restorative materials KetacMolar, Zirconomer, and Zirconomer Improved.For compressive strength evaluation, 30 cylindrical specimens were fabricated measuring 3 mm in diameter and 6 mm in height and grouped into three study groups (n = 10): Group I (KetacTM Molar, 3M, ESPE), Group II (Zirconomer, Shofu Inc., Japan), and Group III (Zirconomer Improved, Shofu Inc., Japan). Data analysis and statistical differences were ascertained using one-way ANOVA with Tukey post-hoc test (p<0.05).Highest compressive strength was exhibited by Zirconomer (321.92 MPa) followed by Zirconomer Improved (302.23 MPa) and Ketac Molar (261.53 MPa). The results analyzed were statistically significant with p-value of <0.001.All the tested restorative materials exhibited sufficient compressive strengths with Zirconomer exhibiting significantly higher compressive strength.
