Effects Of Black Tea And Coffee On The Colour Stability Of Glass Ionomer Cement - An In Vitro Study

Glass ionomer cements are restorative materials which bind to the surface of the tooth and additionally act as filling materials. The colour of the GIC chosen is subjective to the colour of the tooth. The colour stabilising property refers to the ability of the restorative material to maintain colour irrespective of the environmental changes. GIC also has the ability to resist discoloration when exposed to various liquids in the oral cavity. The aim of the present study was to determine the effects of black tea and black coffee on the colour stabilising property of different commercially available glass ionomer cements.
