ClinConnect Summary

This clinical trial is looking at how well a combination of ultrasonic treatment and a special type of laser (called a 980 nm diode laser) works to reduce pain and kill bacteria after dental treatment on certain teeth. Specifically, it focuses on patients who need root canal treatment on a single-rooted tooth that has dead tissue inside and a small area of infection at the tip of the root.

To take part, patients should be between 20 and 35 years old and have a mature, restorable single-rooted tooth with no pain or symptoms but with a small infected area visible on an X-ray (up to 5 mm in size). People with ongoing pain, other health problems, or issues like loose teeth won’t be able to join. If eligible, participants will be informed about the study procedures and asked to give their consent before joining. The goal is to find out if using this laser and ultrasonic method together can help reduce pain and infection more effectively after the dental procedure.
