Abstract(s)
Introdução: A fratura de instrumentos durante o tratamento endodôntico pode ocorrer sendo um dos erros de instrumentação inesperados durante a sua execução, o que pode comprometer o prognóstico e o sucesso do mesmo.
Objetivo: O presente trabalho tem como objetivo a incidência e a etiologia da fratura das limas de instrumentação, e qual o processo e melhor decisão clínica a tomar após a fratura de um instrumento endodôntico.
Metodologia: A revisão da literatura realizada para este trabalho foi baseada nas plataformas Pubmed, ScienceDirect e Google Scholar e pesquisa de bibliotecas universitária da UFP.
Conclusão: A fratura de um instrumento ocorre quando há uma forca de torção excessiva e a fadiga cíclica do instrumento. A gestão delas deve basear-se num conhecimento aprofundado das taxas de sucesso de cada opção terapêutica. Quando a probabilidade de sucesso de remoção do instrumento é baixa, o fragmento pode ser deixado in situ.
Introduction: Instrument fracture during endodontic treatment can occur being one of the unexpected instrumentation errors during its execution, which can compromise the prognosis and or success of the treatment. Objective: The present study aims at the incidence and etiology of instrumental fracture, and what is the process and best clinical decision to make after fracture of endodontic instrument. Methodology: The literature review carried out for this study was based on the Pubmed, ScienceDirect and Google Scholar platforms and UFP university library research. Conclusion: Instrument fracture occurs when there is excessive torsional force and cyclic fatigue of the instrument. Their management must be based on a thorough knowledge of the success rates of each therapeutic option. When the probability of successful removal of instrument is low, the fragment can be left in situ.
