Evaluation of Dentinal Crack Propagation, Amount of Gutta Percha Remaining and Time Required During Removal of Gutta Percha Using Two Different Rotary Instruments and Hand Instruments - An In vitro Study
Abstract:Background:
One of the most important goal of non surgical endodontic retreatment is the successful removal of gutta percha and sealers from the root canal system. A variety of techniques have been recommended for retreatment procedures for the removal of gutta-percha and sealers with or without the help of adjunctive chemical solvents, by using stainless steel hand files or nickel-titanium rotary files, gate glidden burs, heated instruments, ultrasonic instruments, and lasers 1,3.
