Failure of ProFile instruments used with air, high torque control, and low torque control motors
G Yared, P Sleiman - Oral Surgery, Oral Medicine, Oral Pathology, Oral …, 2002 - Elsevier
Objective: The purpose of this study was to evaluate the influence of 350-rpm rotational
speed on the failure incidence of ProFile nickel-titanium rotary instruments (PRI) when used
by an experienced operator in conjunction with different motors. Study Design: Extracted
human mandibular and maxillary first and second molars demonstrating curvatures greater
than 25° were used. PRI sizes 40 to 15 and with 0.06 taper were used in crown-down
fashion at 350 rpm. In groups 1 through 4, air, high torque control, low torque control, and …
