title: An experimental study of the colour changes in composite resins.
abstract: The composite resins are the most frequently materials employed in restorative odontology. One of the shortcomings is the colour stability. Several workers have reported that colour changes can be considerably avoided with use of photo-polymerized composite resins. However, the present investigation demonstrates that several agents, such as coffee, tea and cola, stain photo-polymerized composite resin samples. The maximum staining was observed in the case of coffee followed by tea, cola being the less chromatic agent of the three.
