Resumo
A terapia endodôntica tem como objetivo realizar a limpeza, modelagem e obturação tridimensional dos canais radiculares. Uma das principais dificuldades reside no preparo dos canais radiculares, devido à complexidade anatômica e às limitações dos instrumentos utilizados. Com os avanços da tecnologia e da qualidade dos instrumentos odontológicos, a endodontia mecanizada ganhou espaço com dois tipos de sistemas, o rotatório e o reciprocante, que apesar de conterem cinemáticas diferentes, apresentam um fácil manuseio e uma melhor eficiência clínica. Entretanto, durante os procedimentos endodônticos, esses dois sistemas demonstraram uma aplicação repetida de forças nas estruturas radiculares, resultando na formação de microtrincas, que acabam se expandindo e causando fraturas por toda extensão da raiz. Objetivo: Revisar a literatura existente sobre as técnicas rotatória e reciprocante, em relação à formação de microtrincas no sistema de canais radiculares, e analisar qual sistema está mais relacionado à produção dessas microfissuras. Metodologia: Foram realizadas pesquisas nas bases de dados PUBMED, SCIELO, COCHRANE, AAE (Academia Americana de Endodontia) e SBENDO (Sociedade Brasileira de Endodontia) sobre o tema em questão, e os artigos relevantes foram selecionados manualmente. Considerações finais: Dentro dos limites desta revisão de literatura, se concluiu que o sistema rotatório apresentou uma maior incidência de microtrincas nos canais radiculares após o seu uso, quando comparado ao sistema reciprocante. Entretanto, cada instrumento utilizado na terapia endodôntica possui suas próprias indicações e limitações. E que para se obter sucesso no tratamento de canais, é fundamental ter conhecimento das características dos instrumentos utilizados, compreender a anatomia dos canais radiculares, dominar a técnica adequada e realizar mais estudos sobre o tema.
The objective of endodontic therapy is to clean, shape and fill three-dimensional root canals. One of the main difficulties lies in the preparation of root canals, due to the anatomical complexity and limitations of the instruments used. With advances in technology and the quality of dental instruments, mechanized endodontics has gained ground with two types of systems, rotary and reciprocating, which despite having different kinematics, are easy to handle and have better clinical efficiency. However, during endodontic procedures, these two systems demonstrated a repeated application of forces to the root structures, resulting in the formation of microcracks, which ended up expanding and causing fractures along the entire length of the root. Objective: Review the existing literature on rotational and reciprocating techniques, in relation to the formation of microcracks in the root canal system, and to analyze which system is more related to the production of these microcracks. Methodology: Searches were carried out in PUBMED, SCIELO, COCHRANE, AAE (American Academy of Endodontics) and SBENDO (Brazilian Society of Endodontics) databases on the subject in question, and relevant articles were selected manually. Final considerations: Within the limits of this literature review, it was concluded that the rotary system had a higher incidence of microcracks in the root canals after its use, when compared to the reciprocating system. However, each instrument used in endodontic therapy has its own indications and limitations. And that to be successful in the treatment of canals, it is fundamental to have knowledge of the characteristics of the instruments used, to understand the anatomy of the root canals, to master the adequate technique and to carry out more studies on the subject.
