Efficacy of two rotary NiTi instruments in the removal of Gutta-Percha during root canal retreatment.
The aim of this study was to evaluate the efficacy of ProTaper and K3 in the removal of gutta-percha during root canal retreatment in comparison with hand Hedstrom files. Time of gutta-percha removal and amount of apically extruded debris were also evaluated. Sixty extracted single-rooted anterior teeth and premolars were instrumented and obturated with laterally condensed gutta-percha techniqu...
متن کاملEfficacy of NiTi rotary instruments in removing calcium hydroxide dressing residues from root canal walls.
THE AIM OF THIS STUDY was to evaluate the efficacy of three rotary instrument systems (K3, ProTaper and Twisted File) in removing calcium hydroxide residues from root canal walls. Thirty-four human mandibular incisors were instrumented with the ProTaper System up to the F2 instrument, irrigated with 2.5% NaOCl followed by 17% EDTA, and filled with a calcium hydroxide intracanal dressing. After ...
متن کاملRoot canal retreatment using reciprocating and continuous rotary nickel-titanium instruments
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, follow...
متن کاملCyclic fatigue resistance of rotary NiTi instruments after simulated clinical use in curved root canals.
The aim of this study was to assess cyclic fatigue resistance in rotary nickel-titanium instruments after simulated clinical use in curved root canals (40-degree, 5-mm radius curve). Thirty-six RaCe rotary NiTi files, size #5, taper 0.04, were divided into 3 groups: Groups A, B and C with one, three and five cycles of use, respectively. Time to failure was recorded with a stopwatch in seconds a...
