Mechanical properties of DX Universal Nano Hybrid Composite
Objectives: The aim of the study is to evaluate the mechanical properties of a new dental composite material (DX Universal Nano Hybrid Light Cure Composite by DENTEX) using the standard set by ISO4049:2009.
Methods: Thirty three (33) specimens were prepared to test for depth of cure, flexural strength, water sorption and solubility. Preparation of test specimens, test conditions and procedures, apparatus and treatment of results followed strictly ISO 4049:2009(E).Data were analyzed using mean and standard deviations.
Results: Results shows that the depth of cure has a mean maximum depth of 2.55mm and a mean minimum depth of 1.89mm, for flexural strength the mean is 130.46Mpa, for water sorption the mean result is 16.44µg/mm while solubility has a mean=0.348µg/mm.
Conclusions: The parameters used in evaluating mechanicalproperties of the new nanohybrid composite materials are within the minimum and maximum standard requirement of a poly-based restorative material based on ISO 4049:2009. Further studies on the techanical properties of the new materials should be conducted supplemented by a long-term clinical trial for a more conclusive assessment of the new material.
