Thanks to its chelating properties towards the calcium ion, EDTA 17% gel exerts a demineralizing action on the inorganic component of the dentin, promoting its dissolution and subsequent removal.
The 17% concentration and slightly alkaline pH (approximately 8) represent the ideal conditions for obtaining effective cleansing without attacking the deeper layers of the canal walls.
Unlike the solution, the gel formulation offers the following operational advantages:
- lubricating action that facilitates boring operations.
- suspending action on debris produced by the instruments, which can then be easily removed by subsequent washes.
- greater adhesion to the canal walls which fixes the product in the application area for the necessary time but allows for subsequent easy removal.
Directions for use:
Root canal reaming :
Apply EDTA gel and leave it to act for a couple of minutes before starting reaming. Replace the product removed during the washing phases; once reaming is complete, rinse with hydrogen peroxide or sodium hypochlorite (Niclor 5).
Application of endodontic pins :
After completing the preparation of the recipient site, apply EDTA gel and leave it to act for approximately 5 minutes; then rinse thoroughly with a sodium hypochlorite solution and finally wash with saline solution.
