Aim: To evaluate the effects of sterilization on the color stability of fiberglass-reinforced resin crowns. Methods: A total of 13 primary maxillary central incisor fiberglass-reinforced resin crowns were used to evaluate color stabilization in the study. Vita EasyShade spectrophotometer device was used to analyze color changes. Color measurements of each of the crowns were performed before sterilization (Control Group). Color measurements were performed after first autoclave sterilization (Group 1) and second autoclave sterilization (Group 2). The values were recorded in the CIE L*a*b* system. Clinically acceptability threshold was . . . assumed as ΔE=3.3. Repeated measures ANOVA with Bonferroni post hoc test was used to compare the color measurements (L* a* b* and ΔE) of the crowns after the sterilization cycles. The level of significance was set to α =.05. Results: Discoloration was observed in all crowns after sterilization. A statistically significant difference was found in the ΔE values of the crowns after the first and second sterilization cycles (p < 0.01). The color change of the crowns after the first and second sterilization was above the clinically acceptable value and the color change increased as the number of sterilizations increased. Conclusions: Sterilization causes discoloration of fiberglass reinforced resin crowns. For this reason, it is important to avoid unnecessary trials on these crowns in terms of reducing the number of sterilizations. In this respect, it may be beneficial for the manufacturer to produce trial crowns for use in size selection in the clinical setting
