Can sodium hypochlorite reduce the incidence of emergencies during root canal treatment?
Endodontic interappointment mergers (EIAEs) during root canal treatment refer to the occurrence of varying degrees of pain or discomfort in the affected tooth area, and in severe cases, local swelling or even acute cellulitis, which often occurs after root canal preparation. At present, it is widely recognized that microbial infection is the main cause of EIAE, therefore, infection control has become a very important part of the root canal treatment process. To control infection and prevent the occurrence of EIAE, doctors need to perform their operations in a sterile environment while removing residual infectious substances in the root canal as much as possible. Rubber barrier moisture barrier surgery can completely isolate the affected tooth from the oral cavity, and is currently the most thorough moisture barrier method for root canal treatment. Among commonly used irrigation solutions, sodium hypochlorite has antibacterial and dissolving effects on necrotic pulp tissue, making it one of the most effective root canal irrigation solutions currently available. This study aims to investigate the clinical effect of using sodium hypochlorite flushing combined with rubber barriers for moisture isolation in root canal treatment to reduce the incidence of emergencies during the treatment period.
