Abstract(s)
O tratamento endodôntico não-cirúrgico é realizado nos casos de patologia pulpar e/ou periodontal, com instrumentos minuciosos para retirar a polpa do sistema de canais radiculares, simultaneamente com uma irrigação abundante e finalizado com a obturação do SCR.
O objetivo dessa revisão narrativa será analisar a importância e o desempenho da irrigação na execução de um TENC, caracterizando o tratamento propriamente dito e as propriedades de cada irrigante, vantagens e desvantagens. É importante utilizar diferentes tipos de irrigantes para não inviabilizar o sucesso do tratamento.
O hipoclorito de sódio é o irrigante o mais utilizado pelas suas propriedades antimicrobianas. O EDTA, agente quelante, remove toda a matéria inorgânica a camada de Smear layer. Existe também o ácido cítrico, que tem propriedades similares ao EDTA.
Os diferentes estudos indicam-nos qual é o protocolo de irrigação o mais adequado e quais podem ser as vantagens ou desvantagens dum irrigante sobre um outro.
The non-surgical endodontic treatment is performed in cases of pulpal and/or periodontal pathology, with thorough instruments to remove the pulp from the root canal system, simultaneously with abundant irrigation and finished with the obturation of the RCT. The aim of this narrative review will be to analyze the importance and performance of irrigation in performing a TENC, characterizing the treatment itself and the properties of each irrigant, advantages and disadvantages. It is important to use different types of irrigants so as not to jeopardize treatment success. Sodium hypochlorite is the most widely used irrigant for its antimicrobial properties. EDTA, a chelating agent, removes all inorganic matter from the smear layer. There is also citric acid, which has similar properties to EDTA. The different studies tell us which irrigation protocol is the most adequate, and which may be the advantages or disadvantages of one irrigant over another.
