“…Several techniques for filling materials removal are currently used, including manual and rotary instruments, preceded by the softening of the filling material with heat or solvents appropriate for such purpose. [ 4 5 ] However, no retreatment technique is capable of removing the filling material completely; resulting in residual debris attached to the root canal walls after reinstrumentation. [ 4 5 ]…”

Objective:The complete filling material removal during endodontic retreatment is a clinical procedure difficult to achieve. The aim of this study was to evaluate the efficacy of reciprocating and continuous rotary nickel-titanium instruments used in root canal retreatment.Materials and Methods:Forty freshly extracted human premolars were cleaned and shaped by the crown-down technique, followed by filling by the lateral compaction technique. The teeth were randomly separated into two groups (n = 20), according to the system used for filling material removal: G1 - Reciproc and G2 - ProTaper Universal Retreatment System. The teeth were photographed under operating microscope at ×8 magnification; and the total area of the root canal and remaining filling material were quantified.Results:No statistically significant difference (P > 0.05) in residual filling material was observed between groups; however, the time required for filling removal was significantly shorter for Reciproc system (P < 0.05).Conclusions:It was observed remaining filling material in all teeth, irrespective of the system used; however, root canal retreatment was faster when reciprocating motion was used.

“…For dissolving GP, a nonpolar solvent or less polar solvent must be used. 12 The use of hand files was statistically different from the use of rotary instruments to remove filling material. This probably occurred because of GP plasticization resulting from rotation of the instrument.…”

To evaluate the efficacy and cleaning ability of two different rotary nickel-titanium (NiTi) instruments and hand instruments with and without solvent (Endosolv R) in the removal of gutta-percha (GP) root fillings. Sixty extracted single-rooted anterior teeth were enlarged to size F3 and obturated with warm vertical compaction using AH Plus as the sealer. Removal of GP was performed with the following devices and techniques: Hedstrom files, ProTaper, and R-Endo files. The technique that removed GP most effectively was found using R-Endo instruments and Endosolv R, followed by R-Endo without solvent, followed by ProTaper with solvent, ProTaper without solvent, followed by Hedstrom files with solvent, and Hedstrom files without solvent. There was no visible filling material extruded apically. They concluded that under the experimental conditions, R-Endo and ProTaper NiTi instruments proved to be efficient and time-saving devices for the removal of GP. The use of Endosolv R as a solvent shortened the time to reach the working length (WL) and to remove the GP, but this was not significant.

“…[21] It brings about dissolution of GP by penetrating and separating the polymer chains. [22] It is more biocompatible and displays less cytotoxicity than Xylene. [23,24]In our study Xylene was found to possess better dissolution for all types of GP than Orange oil.…”
