Abstract

Background and Aim: Tooth discoloration induced by endodontic sealers is an un-desired outcome of endodontic treatment that affects the esthetic appearance of the teeth, which is important especially in the anterior region. The aim of the present study was to compare the coronal discoloration caused by two frequently used resin-based sealers namely EasySeal and AdSeal.
Materials and Methods: For this experimental ex-vivo study, 75 intact human maxil-lary central incisors were employed. Access cavities were prepared and the coronal portion of the root canals was instrumented in all teeth. The samples were randomly divided into experimental and control groups (n=15); group A (EasySeal), group B (AdSeal), positive control group (amalgam), negative control group 1 (gutta-percha), and control group 2 (distilled water). The access cavity was sealed by self-cure glass ionomer. Color measurements were carried out using a spectrophotometer at the following time intervals: before the sealer placement (T0), and 1 week (T1), 1 month (T2) and 3 months (T3) after sealer placement. The acquired data were analyzed using the Kruskal-Wallis, Mann-Whitney U, and Wilcoxon signed-rank tests.
Results: The teeth filled by EasySeal showed a significantly higher discoloration than those filled with AdSeal at T2 (P=0.01) and T3 (P=0.05). However, there was no statisti-cally significant difference between EasySeal and AdSeal at T1 (P=0.09).
Conclusion: The results of the present study suggest that both EasySeal and AdSeal cause considerable coronal discoloration. However, EasySeal causes greater coronal discoloration than AdSeal.
