Open publisher page 0 citations

Abstract

The emphasis of the research is on the comparative study of wear rates of four commercially available dental composites. The composites under study were each of micro-filled (3M Z350), nano-filled (Filtek Z250) and nano-hybrid composite (Charisma Diamond) and fibre reinforced composite (GC Ever X). The paper shows the relation between micro hardness and wear rates, regression equations for each composite using RSM optimization technique, Comparison of Wear Rates based on their exact composition, explanation of Residual plots. During study, it was found that the fibre reinforced composite showed better wear resistance over others. The micro hardness is obtained using Vickers hardness test (HV).
