Root canal treatment is performed routinely in dental practice, using sodium hypochlorite which serves as an effective irrigant. The literature reviewed shows that several complications following irrigation with sodium hypochlorite may occur, but few practitioners are aware of it and its management. Such complications include injury to skin, oral mucosa and eyes, damage to clothing, air emphysema, allergic reactions, and injection beyond the foramen. In this article, a case report of injection with sodium hypochlorite beyond the foramen is presented, together with a review of the recent literature regarding common manifestations and case histories. The literature shows no standard management of this condition, but symptomatic therapies are discussed. It is important to minimize the risk of sodium-hypochlorite-induced damage during root canal therapy by use of protective measures, appropriate instrumentation and techniques, and consider alternate irrigation solutions.
根管治疗在牙科实践中是常规操作，使用次氯酸钠作为有效的冲洗剂。回顾的文献表明，用次氯酸钠冲洗后可能会出现几种并发症，但很少有从业者意识到这些并发症及其处理方法。此类并发症包括皮肤、口腔黏膜和眼睛损伤、衣物损坏、气肿、过敏反应以及超出根尖孔的注射。本文介绍了一例次氯酸钠超出根尖孔注射的病例报告，并对近期有关常见表现和病例史的文献进行了综述。文献表明，对于这种情况没有标准的处理方法，但讨论了对症治疗。在根管治疗期间，通过采取保护措施、适当的器械操作和技术，并考虑使用替代冲洗液，将次氯酸钠引起损伤的风险降至最低是很重要的。
