Description

DESCRIPTION
- PD EDTA 17% eases instrumentation and smear layer removal in chemo-mechanical root canal preparation. It is used for root canal irrigation, removal of debris and rinsing.
- Ethylenediamide tetraacetic acid (EDTA) is a chelating agent which combines with the calcium ion and inactivates it, thereby exerting its decalcifying effect on dentine.
- EDTA is active on the inorganic part of the smear layer and must be used alternatively with Sodium Hypochlorite solution to complete its dissolution.
