Summary

Root canal preparation is one of the most important stages in root canal treatment. Nowadays, the use of Nickel-Titanium(Ni-Ti) rotary instrument systems for root canal expansion is becoming very popular. The force required to rotate the Ni-Ti file is defined as the torque force and is considered a parameter for the stress produced within the canal. Ni-Ti rotary instruments can be used with a wide speed scale between 150 rpm (rotary per minute) and 40,000 rpm in conventional endodontic engines.

Low torque and speed values mean low pressure applied by the instruments in the root canal. With low forces and vibrations, motor noise is generally negligible, and the instruments can easily shape most root canals in a reasonable amount of time and with minimal mechanical stress (in medium-easy canals). The use of lower torque values has been shown to reduce cyclic fatigue of Ni-Ti rotary tools. With reduced cyclic fatigue, the risk of instrument breakage in complex root canal morphologies is minimized and complications that may occur during root canal treatment are reduced. However, with low torque and speed values, cutting efficiency decreases and the process time increases as the instrument advances in the canal and during possible treatment. Decreasing cutting efficiency may also result in the operator applying force to move through the canal. With the applied force, the friction resistance within the canal increases and the heat produced increases. For this reason, it is thought that the risk of post-operative pain may increase during or after the procedure.

The aim of this study is to investigate the incidence of post-operative pain and procedure time using the visual analog scale (VAS) among groups where low torque and speed values were applied during the use of the Ni-Ti rotary instrument system.

Conditions

  • Dental Pulp Necrosis

Interventions

DEVICE

use of VDW Silver Endodontic motor

All patients will be subjected to local anesthesia with articaine hydrochloride (Maxicaine, Istanbul) containing 1:100,000 adrenaline. After the entrance cavities of the teeth are opened, a rubber dam will be applied to the relevant teeth for isolation from the oral environment. After the entrance cavity is opened, the working length of the canals will be determined with the help of a No. 10 K-file (Dentsply Maillefer, Ballaigues, Switzerland) canal file and an electronic apex finder (Woodpex III, Woodpecker Medical Instrument Co, Guilin, China). In both groups, it was planned to use the NiTi rotary instrument system using V Taper Gold (Fanta Dental Material, Shanghai, China) files with the help of VDW.Silver endomotor (VDW, München, Germany). The endodontic motor will be used to adjust different speed and torque values during root canal treatment. Post-operative pain caused by different speed and torque values will be compared.
