Paper Abstract

The effect of different beverages on acrylic resin denture teeth color degradation is evaluated. Ten acrylic resin denture teeth brands were evaluated: Art Plus (AP), Biolux (BX), Biotone IPN (BI), Magister (MG), Mondial 6 (MD), Premium 6 (PR), SR Vivodent PE (SR), Trilux (TR), Trubyte Biotone (TB), and Vipi Dent Plus (VP). Teeth were immersed in staining solutions (coffee, cola, and orange juice) or artificial saliva (control) (n=6 ) for 1, 7, 15, or 30 days. Specimen colors were evaluated spectrophotometrically based on the Commission Internationale d’Eclairage L*a*b* system. Color differences (ΔE ) were calculated between the baseline and post-staining results. Data were evaluated by analysis of variance and Tukey test (α=0.05 ). BI (1.82±0.95 ) and TR (1.78±0.72 ) teeth exhibited the greatest ΔE values, while BX (0.88±0.43 ) and MD (1.09±0.44 ) teeth were the lowest, regardless of solution and measurement period, and were different from BI and TR teeth (P<0.05 ). Cola and coffee promoted higher denture teeth color alterations than orange juice and saliva (P<0.05 ). Saliva generated the lowest denture teeth color alterations. Greater immersion times caused higher denture teeth color changes. The lifespan of removable dentures and the aesthetic satisfaction of several edentulous patients may be increased with the use of stain-resistant artificial denture teeth.
