Introduction: Tooth discoloration is an aesthetic problem commonly reported by patients as one of the main reasons to seek a dentist. Thus, this study aimed to evaluate the dentin discoloration caused by AH Plus, MTA Fillapex, Sealer Plus and Pulp Canal Sealer EWT endodontic sealers, associated or not with ultrasonic agitation during the obturation. Methods: Round cavities were prepared on the palatal faces of eighty bovine teeth slabs, preserving a 2 mm of dentin thickness. The slabs were randomly separated in groups by type of sealer employed and based on the use or not of ultrasonic agitation (n = 10). The color was measured by a spectrophotometer after sealer insertion into the cavities (T0), after 7 (T1) and 180 days (T2). Results: Clinically detectable discoloration (∆E > 3,7) was present in all groups at T1 and T2. Statistically significant differences were not found between T1 and T2 (P > .05). Conclusion: All endodontic sealers tested caused dentin discoloration after 7 days. The color-changing persisted thought the entire experimental period. Moreover, the ultrasonic agitation did not influence on the dentin discoloration caused by the endodontic sealers tested.
