Figure 1: A representative photograph of brown precipitate formation after consequent use of sodium hypochlorite and chlorhexidine in experimental conditions.

Mentions: However, the presence of NaOCl in the canals during irrigation with CHX produces an orange-brown precipitate known as parachloroaniline (PCA) (Figure 1).3,10-12 The precipitate occludes the dentinal tubules and may compromise the seal of the obturated root canal.12 Leaching of PCA from the insoluble precipitate is of concern because it has been shown to be cytotoxic in rats and possibly carcinogenic in humans (International Agency for Research on Cancer group 2B).13,14
