RESUMO
A possibilidade da ocorrência de fraturas de instrumentos no interior de canais radiculares com curvaturas significativas ainda é considerada um dos grandes desafios em Endodontia. Diante disso, o objetivo do presente trabalho foi realizar uma revisão de literatura, enfatizando a importância dos instrumentos endodônticos com tratamento térmico Blue na resistência à fadiga cíclica, de modo a fornecer informações expressivas para a escolha de tais instrumentos no uso clínico. Foi realizada uma busca de artigos relevantes sobre a temática entre os anos de 2013 e 2018 nos periódicos PubMed, Science Direct, Scielo e MEDLINE da qual 16 artigos foram selecionados para a leitura na íntegra. O levantamento demonstrou que instrumentos com tratamento térmico Blue apresentaram maior resistência à fadiga cíclica quando comparados àqueles sem o citado tratamento. Portanto, foi possível concluir que o conhecimento acerca das propriedades dos instrumentos é indispensável para que o clínico seja capaz de selecionar o mais adequado, aliando segurança, eficácia e previsibilidade para o tratamento endodôntico de canais radiculares com curvaturas acentuadas.
ABSTRACT
The possibility of fractures of instrument inside root canals with significant curvatures is still considered one of the great challenges in endodontics. Therefore, the aim of this study was to perform a literature review, emphasizing the importance of endodontic instruments with Blue thermal treatment in resistance to cyclic fatigue, in order to provide expressive informations about each suitable instruments in clinical use. A search of relevant articles concerning the subject among the years of 2013 and 2018 was carried out in the periodicals PubMed, Science Direct, Scielo and MEDLINE, of which 16 articles were selected for reading in their entirety. The review showed that Blue heat treated instruments presented greater resistance to cyclic fatigue when compared to those without this treatment. In conclusions, the knowledge about the properties of the instruments is essential for the clinicians to be able to select the most appropriate, combining safety, efficacy and predictability for the endodontic treatment of root canals with accentuated curvatures.
