<br/><br/> The aim of the study is to investigate and compare insitu the effect of halogen light curing unit and high - performance ligt emitting diode light curing unit on some properties of resin composite including color change translucency parameter surface roughness and  surface microhardness . Biodegradation of resin composite by the oral environmental factor has a direct effect on its optical and physical properties
