Comparison Of Colour Stability Of Two Commercially Available Composite Resin Materials After Thermocycling - An In Vitro Study

The colour stability of composites are important because of the aesthetic purposes. Composites are the large amorphous substance of quartz and silica. Composite offers excellent performance material for both anterior and posterior direct replacement restoration. Thermocycling requires a constant temperature in a water bath. The cycle influences the alternate high and low temperatures. This study aims to analyse the effect of thermocycling on colour stability of 2 commercially available composite restorative materials.
