Abstract

Sodium hypochlorite (NaOCl) is the most commonly used irrigant in endodontic procedures due to its potent antimicrobial properties and ability to dissolve organic tissue. However, despite these advantages, sodium hypochlorite can pose significant risks when inadvertently extruded beyond the root canal system. One of the most severe complications occurs when NaOCl extravasates into the maxillary sinus, leading to a range of potential adverse outcomes. This article explores the pathophysiology, clinical implications, and management strategies associated with sodium hypochlorite extrusion into the maxillary sinus.
