Dentists test three common irrigants to ease root canal pain
NCT ID NCT07486245
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested three different rinses used during root canal treatment to see which one causes the least pain afterward. Ninety adults with tooth pain took part, and each received one of the rinses: sodium hypochlorite, hydrogen peroxide, or normal saline. Pain levels were measured after the procedure to help dentists choose the best option for patient comfort.
