Comparative Evaluation of Conventional Heat Cure and Commercially Available Hypoallergenic Denture Base Resins For Color Stability.
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 6
Abstract
Introduction: This in vitro study was undertaken to compare the colour stability of conventional denture base resin (PMMA) and hypoallergenic denture base resins (Alldent Sinomer; Valplast) when exposed to some common beverages (distilled water, tea, coffee, pan masala solution) by means of a spectrometer. Materials and Methods: Three commonly used denture base resins were selected. 5 specimens from the selected test material were stored in each test solution at 370c in a dark environment. Subsequent colour measurements were taken at 1st, 7th and 30th day of immersion using spectrophotometer. Data was statistically analysed by repeated measures ANOVA and the pairwise comparisons by Benferroni corrections to find which groups differed from each other. Results: Significant colour shifts occurred in PMMA, Alldent Sinomer, Valplast in all the test solutions (except distilled water). The colour shift of Valplast in Pan Masala solution was significantly greater than that of remaining test materials in Pan Masala solution. The colour shift of each material in coffee and tea solutions were not significantly different when compared among selected test materials. Conclusion: All denture base resins showed significant colour change at the end of 30 days (p<0.001) though the maximum colour change was observed in Valplast. Clinical Significance: With respect to this study, minimizing the consumption of such beverages and cessation of Pan Masala particularly when Valplast is the denture base material of choice, may be advantageous for denture wearers for long-term colour stability of their dentures.
