The removal of difficult silver cones

Ultrasonics in Endodontics: A Review of the Literature

“…Many instruments and techniques have been reported (42,43). They include appropriate burs (44); special forceps (45); ultrasonic instruments in direct or indirect contact (46 -49); peripheral filing techniques in the presence of solvents, chelators, or irrigants (50); microtube delivery using mechanical adhesion techniques (51); and different kits and extractors (52)(53)(54).…”

“…Several studies have shown that retrieval of silver cones can be performed with traditional techniques using hand instruments and particular devices and extractors (45,50,51,66,124,125).…”

Impact of a Retained Instrument on Treatment Outcome: A Systematic Review and Meta-analysis

“…Surgical techniques for removal of either the object itself or the entire portion of the root encompassing the object have been recommended (18,19). In addition, several authors have introduced special instruments and techniques for intradental retrieval of the obstructing object (10,(20)(21)(22)(23). However, the removal procedure might result in loss of considerable tooth structure and clinical complications such as root perforation (24,25).…”

Removal of Separated Files from Root Canals With a New File-removal System: Case Reports

“…There are various methods and devices developed to retrieve separated instruments. When a fractured instrument extends far above the root canal orifice, it can be easily grasped by a hemostat, Steiglitz forceps, modified Castroviejos needle holder (17), or a Perry plier (18). A spoon excavator or a Caufield retriever (a hand instrument with a V-shaped notch at the tip) can also be used to engage the obstruction and, with coronally directed pressure, it can elevate the obstruction from the canal.…”
