The prolonged demineralizing effect of acetic acid in root canal irrigation

Abstract EN

The aim of the study was to evaluate the prolonged demineralizing effect of the residual 2 % acetic acid left in the root canal after root canal irrigation.

After incubation for 3 and 7 days, the teeth treated with 2 % acetic acid were analysed for change of surface pH, and under SEM for further smear layer removal.

The results revealed that although two percent acetic acid possesses a demineralizing action that opens the dentinal orifices in the coronal and middle thirds of the inner wall of the root canal, and partial demineralization in the apical third, it doesn’t have any further delayed demineralizing action after 3 and 7 days.

In conclusion two percent acetic acid does not have prolonged demineralizing action.
