Colour Stability of Denture Teeth Submitted to Different Cleaning Protocols and Accelerated Artificial Aging


Abstract - Acrylic resin is widely used for artificial teeth manufacturing due to several important characteristics; however, this material do not present acceptable colour stability over the course of time. This study evaluated the effect of different cleaning protocols and accelerated artificial aging on colour stability of denture teeth made of acrylic resin. Sixty denture teeth in dark and light shades were used, and separated according to the treatment to which they were submitted. Results demonstrated that colour stability of artificial teeth is influenced by the cleaning solution and artificial aging, being dark teeth more susceptible to colour alteration than lighter ones.

KEY WORDS: Denture tooth, Acrylic resin, Staining, Accelerated artificial aging.
