Irrigation

MTAD

• The tissue-solubilizing action of MTAD, NaOCl, and EDTA was compared.
• MTAD solubilized dentine well, whereas organic pulp tissue was clearly more unaffected by it.

MTAD & NaOCl

• The effect of various concentrations of NaOCl as an irrigant before irrigation with MTAD as a final rinse on the smear layer was evaluated.
• The results showed that MTAD removed most of the smear layer when used alone; however, remnants of the organic component of the smear layer could be detected on the root canal walls.
• There were no significant differences between the ability of 1.3%, 2.6%, and 5.25% NaOCl as root canal irrigants and MTAD as a final rinse to remove the smear layer. All combinations removed both the smear layer as well as the organic remnants.
