Abstract:
Light-cured composite resins were investigated colourimetrically under the three different conditions, dry and exposed to water and photographic wetting agent. As a result, perceivable differences were found, particularly in photographic wetting agent. We conclude that the colour changes of composite resins seems to be affected by the lower surface tension of a liquid.
