Jefferson J. C. Marion, Thaís Mageste Duque, Bruna Ferreira Gardin, Frederico Campos Manhães

This review shows the accidents and complications that can be caused by inappropriate use of sodium hypochlorite (NaOCl) during the endodontic treatment. This solution has been used since 1920 in concentrations of 0.5% to 5.25% as an antimicrobial irrigant to assist the mechanical preparation of root canals, it is clinically proven to be a lubricant, antiseptic and solvent of body tissue. However, serious accidents, such as skin and intraoral mucosa burns, laryngeal edema, upper airway obstruction, paresthesia, bleeding and others, may occur when used inadvertently. Thus, careful technique, storage and handling must be taken, in order to prevent these undesirable complications. Furthermore, the professional must be able to identify and solve problems when it occurs.
