Sodium hypochloride is used to irrigate the root canals during root canal treatment. Forceful irrigation can result in sodium hypochloride accidents.
Sodium hypochlorite (NaOCl) can be commonly found in a dentist's office. It is used as an irrigant during root canal treatments as it dissolves organic soft tissue of pulp and predentin.
