This
17% solution of EDTA, which
has been buffered to a neutral pH, is used in dentistry
as a very effective calcium "binding" or "chelating"
material to assist in the instrumentation of root canals.
For
root canal cleaning and shaping during instrumentation,
the EDTA solution helps
decalcify the surface of dentin on the canal wall. This
makes it easier to remove dentin with files and reamers
and helps the dentist enlarge and shape the canal for
filling with sealer and gutta percha.
