title: Colour stability of two self curing denture base materials.
abstract: It is important that denture base materials should be colour stable, yet some self curing materials do not fulfill this requirement. Two newly introduced materials, one a 'pour type' resin, were investigated using a sophisticated colorimetric instrument to assess colour changes that might result from contact with water and denture cleansers. Both materials showed measurable colour changes following a two week soaking period, but these were barely perceptible to the eye. The possible reasons for colour instability are discussed.
