What is it about?
To evaluate the colour stability of heat-cure activated acrylic denture base resins {Dental Products of India (DPI) and Trevalon} after staining with tea and coffee, subsequently treated with Clinsodent, Fittydent, and distilled water (control group) as cleansing agents.

Why is it important?
The DPI denture base resin exhibited a highly significant ΔE (change in energy) at 45 days (p=0.0001), while Trevalon showed significance at 60 days (p=0.0079). The difference in means was statistically significant using t-tests for independent samples, and the variance-measure analysis indicated statistical significance in the means of ΔE. The comparison of the three cleansing agents at 60 days was statistically obtained using one-way ANOVA.
Perspectives
The study focused on measuring the colour stability of two base denture resins and the effectiveness of various denture cleansing agents after staining with tea and coffee. It was observed that DPI and Trevalon show statistically significant colour changes when exposed to tea and coffee, with Trevalon showing more variation than DPI. Coffee had a greater staining effect on the samples compared to tea. Staining intensity increased over time, with colour change values (ΔE) rising up to 45 days before stabilising. Clinsodent was found to be more effective than Fittydent in removing stains caused by tea and coffee. To enhance the evaluation of different staining and cleansing agents, future studies could benefit from larger sample sizes. Additionally, conducting studies in patients to assess colour stability may provide further insights into the efficacy of denture materials and cleaning agents.
