  1. * p values are based on the repeated measures Anova test with Bonferroni post-hoc test. Bold numbers represent the statistically significant difference (p < .05). T0, T1 and T2 indicate the base-line color measurement, the color measurement after the first sterilization and the color meas-urement after the fourth sterilization of the crowns, respectively
