Extravasamento de hipoclorito de sódio através do periápiceformas de prevenção: revisão de literatura

Abstract

The use of substances used as auxiliaries in the chemical surgical preparation of the root canal system (SCR) has as its main purpose to generate cleaning, expansionand shaping of the root canal. For this, these solutions must provide antimicrobial action and other properties such as the ability to dilute tissue residues and promote wetting with the intention of facilitating endodontic instrumentation. Among these substances, the ones that stand out the most are NaOCl, Chlorhexidine and EDTA (Ethylenediamine tetraacetic acid). NaOCl used in different requirements for cleaning root canals has been the solution of choice among professionals because it has an antimicrobial action, acts as a tissue solvent, has an alkaline pH, whitening action, is deodorizing and has low surface tension. Thus, the general objective that guided the research was: To clarify, through a literature review, about the extravasation of hypochlorite through the dental apex, to advance its forms of prevention. As for the treatment and prevention of accidents, the present work has immense due to its importance. Therefore, it is essential that the professional and academic understand about its correct handling, ways of prevention and approach to accidents. As forms of prevention, they basically consist of care during irrigation. Thus, the operator must follow a correct plan that aims to prevent accidents, since NaOCl in contact with tissues causes oxidation. It is appropriate to highlight that the NaOCl, despite being generalized, determined, and mastered by professionals, as it can cause discoloration of clothing and tissue damage.
