Summary

This trial compares five different motion patterns used in root canal treatment to see which one causes the least pain afterward. Adults aged 18 to 65 with asymptomatic root canal needs will be randomly assigned to one of the five motion types. Pain levels and inflammatory markers will be measured to identify the most comfortable approach.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
dental file motion type (Twisted Adaptive, Canal Pro Jeni, forward reciprocation, continuous rotation, Optimum Torque Reverse)
What this could lead to
If one motion type consistently causes less pain, dentists may adopt it to make root canals more comfortable.
What could go wrong
This is a small, single-center trial. Results may not apply to all patients or dentists, and pain is subjective.
