Evaluation of wear resistance of opposed recent types of dental composites

Ola Mohamed Ismail Sakr.

Abstract
Background: A wide use of light-activated resin composites, in clinics, has increased recently due to the increased needs for esthetics teeth fillings. This in vitro study evaluated the wear resistance of various direct resin composites with different compositions.
Methodology: Composite samples were divided into three main groups: group A representing 20 discs of Filtek Z350 XT, group B representing 20 discs of Bio active restorative and group C (as antagonist composite) representing 40 discs of Filtek Z250 XT. A programmable logic controlled equipment was used to record the two body wear of tested composites. Images analysis software evaluated the tested samples surface topography. Statistical analysis was performed using studentís t-test and Aasistat 7.6 statistics software.
Results: It was found that group B composite recorded statistically significant higher weight loss mean value; and in antagonistic composite groups, non-significant higher weight loss mean value than group A composite mean value. Also, it was found that group B composite recorded statistically non-significant higher roughness change mean value than group A composite mean value. It was found that group A antagonistic composite recorded statistically non-significant higher roughness change mean value.
Conclusion: A different wear resistance is observed for the two-body wear test, combining the results confirmed that the use of nanoparticles filled resin composites of value reduces abrasion of opposing surface especially with hard fillers like zirconia. A higher filler load in excess of 60 (vol %) results in increasing wear resistance although that softer glass particles filler was used.

Key words: Resin composites, wear resistance, bioactive material, nano fillers, nanohybrid fillers
