Different endodontic motor motions during root canals and their effect on pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, randomized trial compares six groups that use rotary or reciprocating instrumentation with various apical motion modes during primary root canal treatment of mandibular premolars. All procedures follow a standardized protocol and are performed under local anesthesia and rubber dam isolation. Postoperative pain will be tracked using a standardized pain scale to see if motor settings influence short-term discomfort. The study focuses on clinically routine practices to determine if motion algorithms affect debris extrusion, apical stress, and tissue irritation linked to pain.
