Silver point extended below canal orifice:
- This discrepancy between the round silver wire and an irregularly shaped canal provides the clinician with an opportunity to use solvents and solvent-filled chamber.
- A size 10 or 15 SS file slide laterally alongside the SP to break up cements and to undermine and loosen the silver point for removal.
- In underprepared canals, chelators are better than solvents by allowing the instrument to slip and slide and work laterally to the silver point.
-Then used file size 30,35 or 40
-The "Hedstrom displacement technique powerfully due to positive rake angle bites, engages and establishes a strong purchase on any metallurgically soft silver point.
