About this trial

Brief Summary

This prospective, randomized clinical trial aims to evaluate the effect of different endodontic motor settings used during root canal treatment on postoperative pain.

During root canal treatment, the inner part of the tooth is cleaned and shaped using specialized rotating instruments. These instruments can operate with different motion patterns, and the motor may respond differently as the instrument approaches the tip of the root. The influence of these technical variations on postoperative pain has not been clearly established.

Adult participants requiring root canal treatment for mandibular premolar teeth will be enrolled in the study. Participants will be randomly assigned to different groups. In each group, root canal treatment will be performed using different motor motion settings. All procedures applied in this study are routine and safe treatment methods commonly used in clinical endodontic practice.

After treatment, participants' pain levels will be monitored through telephone follow-ups. Pain intensity will be assessed using the Visual Analog Scale (VAS). In addition, analgesic intake will be recorded.

The purpose of this study is to determine whether different endodontic motor settings influence postoperative pain and patient comfort following root canal treatment. The findings are expected to contribute to safer and more comfortable root canal treatment protocols.

Trial outcomes

Primary outcomes

1

Postoperative Pain Intensity

Postoperative pain intensity will be assessed using a 10-cm Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst pain imaginable). Higher scores indicate greater postoperative pain intensity. The same outcome measure will be assessed repeatedly at predefined postoperative time points to evaluate changes in postoperative pain intensity over time.

Time frame
Repeated measurements at 6 hours, 12 hours, 24 hours, 48 hours, and 7 days after treatment.

Secondary outcomes

1

Analgesic Intake

Analgesic intake will be assessed as the total number of analgesic tablets taken by each participant during the first 7 days after treatment.

Time frame
Within 7 days after treatment
