Acidentes com hipoclorito de sódio na endodontia: uma revisão da literatura

Abstract

Introduction: Success in endodontic treatment depends on the effective removal of bacteria and bacterial toxins from root canals. Sodium hypochlorite (NaOCl) is widely used for disinfection, with concentrations of 0.5% to 5.25%. Extrusion of NaOCl can result in periapical lesions, swelling and pain, requiring precautions during irrigation to avoid accidents. Understanding complications and anatomical patterns of teeth is essential to prevent accidents with NaOCl and ensure safe and effective treatments. Objective: This work aims to address the different cases of sodium hypochlorite, the appropriate conduct and describe the mode of prevention in order to avoid such adversities. Materials and Method: 21 articles were selected indexed in different databases such as PubMed, SciELO and specific journals in the area, where the descriptors were “accident”, “endodontic”, “apical” and “sodium hypochlorite” in the period of 10 years published between 2013 and 2023. Conclusion: The review emphasizes the importance of understanding the risks of sodium hypochlorite in Endodontics, highlighting the need for rigorous preventive measures to avoid injuries and ensure patient safety and the success of endodontic procedures.
