Root canal solutions: which causes less pain?
Part of Pain clinical trials.
This study compares two root canal cleaning solutions (chlorhexidine and sodium hypochlorite) to see which one causes less pain after treatment. If you need a root canal and meet the health criteria, you may be able to help choose the gentler option.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You need a root canal on a tooth that has not been treated before.
- You do not have an allergy to the cleaning solutions chlorhexidine or sodium hypochlorite.
- You do not have a condition or take medication that changes how you feel pain (like diabetes with nerve damage, fibromyalgia, or daily painkillers).
- You are not pregnant or breastfeeding.
- The tooth for treatment is not loose, doesn’t have an open tip (open apex), and its roots are not damaged.

This study compares two different methods of delivering a cleaning solution during root canal treatment to see which one causes less pain and discomfort after the procedure. Participants will be randomly assigned to one of the two methods.
This study compares two different strengths of a cleaning solution used during root canal treatment to see which one causes less pain afterward. Root canal treatment cleans out infected or damaged tissue inside a tooth; this trial tests whether the cleaning solution's strength affects your pain recovery.
This study compares two root canal cleaning solutions (calcium hypochlorite vs. sodium hypochlorite) to see which one causes less pain and reduces bacteria better in lower premolars with dead nerves. If you have a tooth that needs a root canal and is not infected severely, you may qualify.
This trial tests if different concentrations of sodium hypochlorite (a disinfectant used in root canals) affect pain and certain natural chemicals in the tooth during root canal retreatment. It may help find the best option to reduce discomfort.
This trial compares two different ways of cleaning and shaping the inside of a tooth (root canal) to see which one causes less pain afterward. It is for people with a specific type of tooth infection in a lower back molar.
This study compares two different techniques for cleaning and shaping root canals (the nerve chambers inside teeth) to see which one causes less pain after treatment. If you have a dead nerve in a back lower tooth, this trial may help us understand the best way to treat it with minimal discomfort.
