Abstract
Objective: The aim of this study was to evaluate the effect of different times and exposure time of different solutions on coloration. Material and Method: In this study, 60 pieces of 13 mm diameter and 1.5 mm thick composite blocks were used. Five different solutions (tea, coffee, cola, red wine and distilled water) were used for the staining procedure. Samples were analyzed by using spectrophotometer and color changes according to the time and solutions they were kept in the solutions. Color values of each sample kept in solutions for 30 days. 1, 2, 7. On the 21st and 30th days, the color change values (∆E00) were calculated. Statistical analyzes were performed by comparing the ANOVA in multiple groups with the Bonferonni test in paired comparisons, when the mean values of the data provided normal distribution. Kruskall Wallis and Mann Whitney-U test were used for nonparametric conditions Results:In the study, the differences of the samples according to the days and the solutions used were not statistically different between the coloration measurements of the water from day 1 to day 30 (p = 0.205). In all other solutions, the colorings increased with time. After 30 days, all mean measurements were statistically increased in tea, instant coffee, cola and wine solutions (p <0.001). Conclusion: The color of the samples kept in colorant solutions increased with time. The highest coloration of wine in distilled water while the samples are kept in time showed no statistical difference in color.
