Abstract
Context: This study evaluated and compared the shaping ability of ProTaper Gold
(PG) (PG; Dentsply, Tulsa Dental Specialties, Tulsa, OK, USA) system with ProTaper Universal
(PU) (PU; Dentsply Maillefer, Ballaigues, Switzerland) using cone‑beam computed tomography
(CBCT) imaging.
Materials and Methods: Forty mesiobuccal canals of mandibular first molars with curvatures
of 25−30° were divided into two experimental groups (n = 20) according to the rotary
nickel–titanium (NiTi) file system used in canal instrumentation as follows: Group PG and
group PU. Canals were scanned before and after instrumentation using CBCT scanner to evaluate
root canal transportation and centering ratio at 3, 5, and 7 mm from the apex and volumetric
changes. Data were statistically analyzed using independent t‑tests and the significance level
was set at P < 0.05.
Results: There was no significant difference between PG and PU systems in the mean volume
of removed dentine, canal transportation, and centering ratio (P > 0.05).
Conclusions: The PG and PU NiTi rotary systems showed similar root canal shaping abilities
in the preparation of mesial canals of mandibular first molars.
