摘要：

Two types of endodontic files (ProFile and Mtwo) were studied in order to analyze the effect of geometry on the stress-induced martensitic (SIM) transformation during bending. The use of a fine beam spot of synchrotron radiation allowed a detailed structural characterization with a fine spatial resolution. Experimental evidence of the effect of the cross-section geometry on the stress localization giving rise to different degrees of SIM transformation is presented for the first time in the published literature.
