Resumo: | The objective of this study was to perform a comparative analysis of the fatigue strength of NiTi instruments in an in vitro model (artificial canal). Ten Hyflex EDM instruments (tip: 10; taper: .05) (Coltene/Whaledent, Altstätten, Switzerland) and ten Bassi LogicTM instruments (tip: 15; taper: .05) (Bassi Endo, Belo Horizonte, Brazil) were used. For the static bending fatigue strength test, we used a stainless-steel artificial canal with a 5-mm curvature radius, 90º curvature, and inner diameter of 1.5 mm. The instruments were run in the artificial canal until the occurrence of fracture. The time was recorded and the number of cycles was calculated. The length of the fragments was measured and three samples from each group were analyzed using scanning electron micrscopy for the characterization of metal fatigue. The data were compared using the nonparametric Man-Whitney test (samples with non-normal distribution), with the significance level set at 5% (p<0.05). Bassi LogicTM instruments tolerated a greater number of cycles compared to the Hyflex EDM (p < 0.05). Significant differences in fragment size were also found between groups (p < 0.05). Mean fragment size was larger among the Hyflex EDM instruments compared to the Bassi LogicTM instruments.The Bassi LogicTM 15.05 exhibited greater fatigue strength in artificial canals with an accentuated curvature compared to Hyflex EDM 10.05. |

En este trabajo se incluyeron diez instrumentos Hyflex EDM (Coltene/Whaledent, Altstätten, Suiza), punta 10, conicidad .05 y 10 instrumentos Bassi LogicTM (Bassi Endo, Belo Horizonte, Brasil), punta 15, conicidad .05. Para el ensayo de resistencia a la fatiga por flexión estática se utilizó un canal artificial de acero inoxidable con un radio de curvatura de 5 mm, un ángulo de curvatura de 90º y un diámetro interno de 1,5 mm. Los instrumentos se rotaron en los canales artificiales hasta que se produjo la fractura, se registró el tiempo hasta la fractura y se calculó el número de ciclos hasta la fractura. Se midieron las longitudes de los fragmentos rotos y se evaluaron 3 muestras de cada grupo en microscopía electrónica de barrido para caracterizar la fatiga metálica. Los datos fueron evaluados por la prueba no paramétrica de Mann-Whitney (para muestras sin distribución normal). El nivel de significación establecido fue p<0,05. Los instrumentos Bassi LogicTM 15.05 mostraron una mayor resistencia a la fatiga en canales artificiales con curvatura acentuada, en comparación con los instrumentos Hyflex EDM 10.05.O objetivo do trabalho foi avaliar comparativamente a resistência à fadiga por flexão de instrumentos de NiTi através de modelo in vitro (canal artificial).

Para o teste estático de resistência à fadiga por flexão, utilizou-se um canal artificial de aço inoxidável com um raio de curvatura de 5 mm, um ângulo de curvatura de 90º e um diâmetro interno de 1,5 mm. Os instrumentos foram girados nos canais artificiais até a ocorrência da fratura, tempo de fratura foi registrado e foi calculado o número de ciclos até a fratura. Foram medidos os comprimentos dos fragmentos rompidos e 3 amostras de cada grupo foram avaliadas em microscopia eletrônica de varredura para caracterização da fadiga metálica.
