  Influence of storage temperature on vickers microhardness of resin composite
  Author(s): Mayyadah Almozainy*
  
  Introduction: The purpose of this study is to evaluate the effect of three storage temperatures on microhardness of high and low viscosity bulk-fill materials and compare them with conventional resin-based composite materials. Materials and method: Six composite resin-based materials were used in this study (TN, TNB, TNF, FZ250, FB and FBF) samples were subdivided into three groups based on the pre-curing storage temperature (5°C, 23°C and 37°C). Light polymerization for each material was performed based on the manufacturer’s recommendation using Bluephase G2 curing unit (Ivoclar Vivadent, Schaan, Liechtenstein) in a high-intensity mode with an irradiance of 1200 mW/cm2. Vickers hardness values of top and the bottom surfaces of each sample were evaluated using (NOVA 130 series, Vickers .. View More»
