Comparing two methods for root canal pain relief in lower molars
Part of Pain clinical trials.
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.
