| description | Purpose:
To evaluate the effect of commonly consumed beverages on the color stability of heat cure acrylic resin (Vertex rapid simplified, Holland).
Materials and Method:
Sixty heat cure acrylic resin specimens measuring 13.0 mm in length and 4.0 mm thickness were prepared using a stainless steel mold. Specimens were randomly allocated into 6 groups (n= 10): baseline, distilled water, coke, tea, turmeric powder solution and coffee solution. A digital spectrophotometer was used to evaluate color changes after 30-days immersion in each solution. Specimens were stored in different staining media for 24 hour/day for 30 days.L*a*b* color space (CIE L*a*b*) known as Commission International ed’Eclairage is used to evaluated the colour changes of the material. Analysis of data was done by using one way analysis of variance (ANOVA) for a quantitative dependent variable by a single factor (independent) variable. To identify which of the mean differed significantly, Dunnett t (2 sided) was used at 0.01 significance level at 99% confidence level.(p<0.01).
Results:
Statistically significant differences were found in the color change (ÄE) among all groups (p < 0.001) after 30 days of immersion. At baseline (0 day), trace amount of color change was observed where as appreciable changes were observed when specimens were immersed in Turmeric powder, coffee and tea.
Conclusions:
These results of the study conclude that the color stability of denture base acrylic resin is influenced by commonly used beverages.
