Abstract: (1719 Views)
Background: Considering the prevalence of color changing of shade guides resulting from the use of disinfectants, the aim of the present study was to evaluate the effect of two disinfectants Desomed and Deconnex +53 on Vitapan shade guide.
Methods and materials: The present experimental–in vitro study was conducted on a total of 30 A2 shade tabs. In the case group, 10 samples were merged in each of disinfectants and 10 sample were placed into distilled water as control group. Color selecting process was performed for 5 days, 3 times a day, by dentist. After 480 repeated cycles of this procedure, according to CIELab system, primary color of 10 samples were measured using Konica Minolta spectrophotometer as the control group. Also, color indices were measured making using of Vident spectrophotometer in the CIELAB system. Statistical analyses were performed running Two-way ANOVA.
Results: The rate of color change indices showed that the color changing (ΔE) indices for Deconex+53 and Desomed were 1.23∓0.55 and 3.69∓1.3, respectively. Thus, the ΔE of Desomed was twice more than that of Deconex +53. Our results revealed that the discoloration of Desomed was statically
significant and higher than that of Deconex (p<0.001).
Conclusions: It can be concluded that Desomed has more color changes compared with Deconex in similar conditions.
