A liquid ethylenediaminetetraacetic acid (EDTA) solution used to dissolve the smear layer, soften the root canal dentine chemically, and improve dentine permeability.
The root canal is irrigated with 15–17% EDTA solutions to remove the smear layer.
Solution of 17% ethylenediaminetetraacetic acid buffered to pH neutral.
It is utilized to make root canal instrumental treatment simpler.
The mineral components in the hard tissues of the tooth cause EDTA to react, which is how it functions.
By liquifying the tissues, the chelating substance EDTA decalcifies the canal walls.
It makes it easier to remove the smear layer and mechanically prepare the root canal, which opens the dentin tubules.
