Effect Of Different Resin Thickness On Some Physical Properties Of Sonic Fill Versus Bulk Fill Resin Composite, Omnia Nour, Maha Niazy, Sameh Nabih

Al-Azhar Journal of Dentistry

Purpose: This study evaluated the effect of resin thickness from both {Sonic Fill resin composite (SF)& Tetric N Ceram Bulk Fill resin composite (TNB)} on polymerization shrinkage strains, depth of cure and degree of conversion. Material and Methods: A total of 70 specimens were prepared and Polymerization shrinkage strains were measured by strain gauge foil connected to the computer software program which gave the results. Depth of cure (DOC) was measured by Vickers microhardness tester applying a 50g load through a Vickers indenter with a dwell time of 10s and expressed as mean of hardness ratio. Degree of conversion (DC%) …
