Abstract :
Introduction: A desirable quality of any endodontic sealer is its ability to be tooth color
friendly. Therefore the aim of the present study was to evaluate the tooth discoloration
potential of a nano zinc oxide-eugenol (NZOE) sealer. Methods and Materials: In order to
evaluate tooth discoloration, the pulp chamber of 60 human maxillary central and lateral
incisors were filled with one of the sealers, naming AH-26 (resin-based sealer), Pulpdent
sealer (ZOE-based) and a NZOE experimental sealer. Color measurements was assessed at
the baseline (before placement of sealers) (T0), 24 h (T1) and 72 h (T2) h, 1-week (T3), and
1-month (T4) after the placement of sealers using the Easy Shade spectrophotometer. Data
were analyzed in SPSS software using one-way ANOVA, and repeated measured ANOVA.
Results: No significant differences were observed when the paired comparison test was
performed (P>0.05). Conclusion: The tested NZOE sealer had similar tooth discoloration
potential in comparison with AH-26 and ZOE sealer.
