Abstract：
Sodium hypochlorite (NaOCl) is one of the most commonly used irrigant because of its several advantages. However, it is highly cytotoxic and can lead to severe tissue damage. NaOCl accident occurs when it is extruded beyond root confines into periapical or periradicular tissues. It is an irrigant mishap which can be life threatening and/or cause residual or long term or permanent consequences with malpractice and medico-legal implications. There are many factors which can influence the occurrence and progress of NaOCl accident. These factors can be broadly categorized as patient (host)-, tooth-, operator-, and NaOCl-related factors. They can be further categorized as predisposing and extent factors. It is vital for a clinician to thoroughly understand and identify various influencing factors to prevent NaOCl accident with its associated consequences including any potential medico-legal issues. The purpose of this article is to provide a narrative review on various factors which predispose to the occurrence of NaOCl accident and influence its extent and/or outcome.
摘要：
次氯酸钠（NaOCl）是最常用的冲洗剂之一，因为它具有多种优点。然而,它具有高度细胞毒性，可导致严重的组织损伤。当NaOCl超出根范围进入根尖或根尖周组织时，就会发生事故。这是一种灌溉事故，可能危及生命和/或导致残余或长期或永久性后果，并伴有渎职和医疗法律影响。影响NaOCl事故发生和进展的因素很多。这些因素可以大致归类为患者（宿主）-，tooth-,操作员-,和NaOCl相关因素。它们可以进一步分类为诱发因素和程度因素。临床医生必须彻底了解和识别各种影响因素，以防止NaOCl事故及其相关后果，包括任何潜在的医学法律问题。本文的目的是对易于发生NaOCl事故并影响其程度和/或结果的各种因素进行叙述性回顾。
