Introdução: O presente trabalho introduz um novo tema na área da Endodontia: Reciclagem Seletiva de Canais Radiculares. Tem os mesmos princípios de desinfecção, conformação e obturação que o retratamento endodôntico não cirúrgico convencional, no entanto é menos invasivo. Está indicado em casos de insucesso prévio no tratamento endodôntico e na presença de próteses.
Objetivos: Esta dissertação tem como objectivo principal apresentar um possível novo tratamento na área da Endodontia. Procedeu-se a uma revisão bibliográfica, analisando a literatura que versa o tema, de modo a introduzi-lo dentro da área do retratamento endodôntico não cirúrgico nos seus diferentes procedimentos: Desobturação e materiais utilizados, instrumental utilizado, irrigantes e a sua utilidade e aplicabilidade na prática clínica.
Materiais e Métodos: Para a elaboração da presente dissertação, foi realizada uma pesquisa bibliográfica, no presente ano, recorrendo-se aos motores de pesquisa on-line: b-On, Pubmed, Scielo e Google Académico, realizando a pesquisa através das palavras-chave: “endodontic retreatment”, ”root canal system”, “endodontic irrigation”, “endodontic solvent”, “pro-taper”, “reciproc”, “clorohexidine”, “sodium hipoclorite”, “obturation” que foram então combinadas entre si de múltiplas e sucessivas formas. Foram utilizados 50 artigos dos 87 seleccionados, um livro e uma revista.
Discussão: Na literatura científica, são comparados vários materiais para a realização do retratamento endodôntico não cirúrgico, como solvente o que melhores resultados apresenta na dissolução da Gutta-Percha é o Xilitol seguido do clorofórmio. Como solução irrigante a Clorohexidina tem um grande potencial nos casos de retratamento por ser mais eficaz em bactérias Gram+ e pela sua substantividade que permite que a sua actividade bacteriana seja contínua. O sistema Reciproc® pela sua forma em S no corte transversal e possuir dois bordos cortantes, aliados à sua composição pela nova liga M-Wire, mais resistente à torção e fadiga cíclica parece ser a melhor opção tanto para desobturação do SCR como re-instrumentação. Com a imagiologia tridimensional, a Reciclagem Selectiva de Canais Radiculares pode ser explorada e tornar-se uma técnica mais conservadora em casos de retratamento ao conseguir-se determinar qual a raiz com lesão apical. Conclusão: Perante este novo método mais conservador de realizar o retratamento endodôntico não cirúrgico, o exame radiológico por CBCT é o grande responsável pela sua realização. Com ele podemos ter acesso à tridimensionalidade de todas as estruturas orais e consequentemente atingir um diagnóstico correcto, com mais informação disponível. Este novo método, aliado aos melhores materiais utilizados no RTENC convencional poderão permitir ao clínico a realização de um retratamento não cirúrgico seguro, mais conservador para a estrutura dentária e para potenciais próteses que possam estar presentes. São necessários mais estudos com um follow-up mais prolongado para determinar a real efetividade deste tratamento.
Introduction: The following paper introduces a new theme in the Endodontics field: Selective Root Canal Treatment. It has the same principles of disinfection, conforming and obturation than the conventional nonsurgical root canal retreatment, however, is less invasive. It is indicated in cases of previous insucess in endodontic treatment and in the presence of prosthesis. Objectives: This thesis main goal is to introduce a possible new treatment in the Endodontics field. A literature review has been done analyzing the existing literature in order to investigate the theme and in a way to introduce him in the nonsurgical endodontic retreatment in their different procedures: Filling removal and the instruments used, used instrumental, irrigants, its use and applicability in clinical practice. Materials and Methods: In the carrying out of this literature review, it was used the online search engines, in the present year, such has: b-On, Pubmed, Scielo and Google Scholar, implementing research through the keywords: ―endodontic retreatment‖, ‖root canal system‖, ―endodontic irrigation‖, ―endodontic solvent‖, ―pro-taper‖, ―reciproc‖, ―clorohexidine‖, ―sodium hipoclorite‖, ―obturation‖ combined afterwards between themselves. In total, 50 articles were used of the 87 selected, one book and one magazine. Discussion: In the scientific literature, several materials are compared to perform the nonsurgical endodontic retreatment as solvent shows that better results in the dissolution of Gutta-percha is xylitol followed by chloroform. As irrigating solution Chlorhexidine has great potential in retreatment cases to be more effective on Gram + bacteria and their substantivity which enables its bacterial activity is ongoing. The Reciproc® system for its S-shape in cross section and has two cutting edges, combined with its composition by new alloy M-Wire, more resistant to torsion and cyclic fatigue seems to be the best option for both SCR removal procedure as re-instrumentation . With the three-dimensional imaging, selective recycling of root canals can be exploited and become a more conservative technique retreatment cases to achieve determine which is the root apical lesions. Conclusion: Faced with this new, more conservative method of performing nonsurgical endodontic retreatment, radiological examination by CBCT is largely responsible for its realization. With it we can have access to the three-dimensionality of all oral structures and consequently achieve a correct diagnosis, with more information available. This new method, combined with the best materials used in conventional RTENC may allow the clinician performing a nonsurgical retreatment safer, more conservative for the tooth structure and potential prosthesis that may be present. Further studies are needed with longer follow-up to determine the actual effectiveness of this treatment.
