Effect of Rotary File Number on MB2 Canal Negotiation and Postoperative Pain

Effect of Number of Rotary Instruments on Negotiating Second Mesiobuccal Canals to Working Length and on Postoperative Pain: A Randomized Clinical Trial

Sponsor

Mehmet Adıgüzel

Enrollment

152 participants

Start Date

Jun 18, 2025

Study Type

INTERVENTIONAL

Conditions

Postoperative Pain Pulp Necrosis

Summary

This randomized controlled clinical trial aims to evaluate the effect of the number of rotary files on working length negotiation and postoperative pain in the second mesiobuccal (MB2) canals of maxillary first molars. Patients are assigned to one of four groups according to the number of rotary files used: single-, two-, three-, or four-file systems. Postoperative pain is assessed on each of the seven consecutive postoperative days (Days 1-7) using a visual analog scale (VAS), and working length negotiation success is recorded during canal instrumentation.

Eligibility

Interventions

DEVICEOneCurve Rotary File

A single-file NiTi system (25/.04) operated at 300 rpm and 2.5 Ncm torque. Applied directly to the MB2 canal without prior hand instrumentation.

DEVICEPerfect Minimally Invasive Kit

Two-file system using 10/.06 Shaper for coronal/middle thirds and 25/.04 Finisher for apical third. Operated at 300 rpm and 2.0-2.5 Ncm torque.

DEVICEVDW Rotate

Three-file NiTi rotary system (15/.04, 20/.05, 25/.04) used sequentially for coronal, middle, and apical thirds. Applied with brushing-pecking motion in 2-3 mm increments under continuous irrigation. Operated at 300 rpm and 1.8 Ncm torque.

DEVICEPerfect Advanced Kit

NiTi rotary file system including 10/.07 Opener, 10/.04, 17/.05, and 25/.04 files. Used in crown-down sequence with rpm and torque settings ranging from 250-300 rpm and 2.0-2.5 Ncm. Brushing-pecking motion and continuous irrigation were applied during instrumentation.
