In vitro assessment of tooth color alteration by two different types of endodontic irrigants.

Aim: The purpose of this study was to assess in vitro the tooth color alterations associated with two commonly used endodontic irrigants, the chlorhexidine gluconate (CHX) and the sodium hypochlorite (NaOCl) up to 15 days post-treatment. Additionally, the possible influence of endodontic access preparation on tooth color was investigated.

Materials And Methods: Thirty intact human anterior teeth were used.
