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).
