The aim of this study was to analyse the colour stability of acrylic teeth, after exposure to several dietary agents (types of coffee, red wine), and the oral antiseptic chlorhexidine (0.2% mouthwash). Distilled water was used as control. The teeth colour was assessed using a spectrophotometric method. Acrylic teeth from 4 manufacturers were immersed in staining agents over a period of 11 days. Acrylic teeth showed a high susceptibility to staining, dependent on teeth manufacturer (lowest for Vita teeth), and staining agent (highest for coffee, especially espresso, and for red wine). Chlorhexidine mouthwash had a low staining potential, similar to distilled water. In conclusion, tests for staining susceptibility can be carried out by spectrophotometry before selecting teeth from one manufacturer, using specific colouring agents according to patient food preferences. Chlorhexidine, an oral antiseptic frequently prescribed, has low staining potential of acrylic teeth.
