Effect of irrigation solutions on the coronal discoloration induced by mineral trioxide aggregate cements containing different radiopacifiers

Conclusion: Under the condition of this ex vivo study, irrigation of dentin with NaOCl and CHX andthen removing the excess solution might be ineffective in increasing the tooth color change potentialof either bismuth oxide or zirconium ‑containing calcium silicate‑based materials. Furthermore,calcium silicate ‑based material, which contained bismuth oxide, caused higher tooth discoloration.Key Words: Calcium silicate, chlorhexidine, mineral trioxide aggregate, root canal irrigant,sodium hypochlorite, tooth discoloration
