Chemical Root Canal Debridement


The success of endodontic treatment depends on the eradication of microbes from the root canal system and prevention of re-infection. Mechanical instrumentation and irrigation are considered the most important factors in the eradication of microbes from root canal system. Irrigation is also the only way to impact those areas of the root canal system not touched by mechanical instrumentation. During root canal therapy, endodontic irrigants help to remove the debris, dissolve organic tissues, kill microbes, and remove the smear layer. There are numerous root canal irrigants which are used in day to day endodontic practice. This lecture describes the technique of debridement of root canal system using root canal irrigants.
