Aim: This in vitro study compared the coronal discoloration effect of three endodontic sealers at short-time intervals. Materials and Methods: The crowns of 50 extracted premolars were cut and their pulp chambers were cleaned and randomly divided into five groups ( n = 10). The following materials were placed into the pulp chambers: Group I: AH Plus, group II: Apexit Plus, group III: Sultan, group IV: Amalgam, and group V: Distilled water. The color of the crowns was measured using Shadepilot TM spectrophotometer (DeguDent, Hanau, Germany) prior and after the placement of experimental materials within pulp chambers. Color changes (ΔE values) and shades were recorded in 3, 10, and 17 days. A Kruskal-Wallis and Mann-Whitney tests were used to assess significant differences between the sealers. Wilcoxon test was used to compare color changes at different periods within each group. Results: All sealers showed significant discoloration effect that increased over the time. At the end of the observation period, Apexit Plus showed the lowest coronal discoloration effect (ΔE = 6.38 ± 0.55). Conclusions: All sealers used in the current study may cause a progressive coronal discoloration effect over 10-17 days. Apexit Plus sealer showed the lowest coronal discoloration effect.
