Root canal negotiation began with pre-curved, small-diameter K files
(K6/ K8/ K10), without immediately attempting full root canal
catheterization (Fig 17,18).
We also opted for abundant irrigation with sodium hypochlorite, which
has a solvent action on the organic substances involved in pulpolite
adhesion. The addition of a lubricating and chelating gel (EDTA)
facilitated instrument insertion and eliminated the mineral phase of the
pulpolites.
Once negotiation to the working length had been achieved, advancement
into the canal became easier with rotary Niti instruments always under
abundant irrigation (Fig 19,20,21,22).
