Objective: This study intended to evaluate how 3 types of resins, by name Paladent 20 (Heraeus Group, Hanau, Germany), SR Triplex Hot (Ivoclar Vivadent Inc., Schaan, Liechtenstein), and QC-20 (Dentsply Sirona, York, PA, USA), commonly used as denture materials in the clinical field were influenced by edible materials such as coffee and black tea.
Methods: Three experimental specimens were prepared for each type of resin and were used in measuring their color changes with a spectrophotometer. After depositing a specimen for each type of resin in 3 sample solutions (coffee, black tea, and distilled water) contained in 3 separate beakers, the color change in each specimen was measured on 1, 5, 10, and 15 days. The L* value, a* value, and b* value were measured, and the ΔE* value was calculated for each specimen.
Results: Each type of resin showed differences in color change over time (p=0.004), but did not display color change depend ing on the different solutions (p=0.920). The QC-20 and the SR Triplex Hot showed comparable color stabilization and exhibited the same degree of color stabilization as that of the general curing resin. Paladent 20 demonstrated somewhat poorer color stabili zation in the black tea solution. For the full dentures, any spot with insufficient polishing showed poor discoloration.
Conclusion: Paladent 20 appears to be more discolored than the other resins when exposed to black tea solution. Hence, pa tients with dentures made of Paladent 20 should not be recommended to drink black tea habitually.
