A case from the Philippines Dr Margaret Tiu, a clinician based in the Philippines, agrees that the increased fatigue re- sistance and strong flexibility of both HyFlex systems allowed her to manage an S-shaped case more easily. At a recent COLTENE Train the Trainer event (Fig. 4), she presented a mandibular first molar case with four canals that was referred to her by an- other dentist (Fig. 5) who could not negotiate the canal owing to its difficult anatomy (Fig. 6). After utilising the crown-down technique and the HyFlex CM files to flare the coronal third of the distobuccal and distolin- gual canals, Tiu then continued to use HyFlex EDM to negotiate the mesiobuccal and mesiolin- gual canals, as she had discov- ered a slight curvature in the middle third of the canals. As for the S-shaped distobuccal and distolingual canal, she con- tinued with the Hyflex CM files. Post-op radiograph showed prop- erly shaped canals with proper healing (Fig. 7). 23 – 25 March 2018 AUSTRALIA’S PREMIER DENTAL EVENT SEE MORE B UY MORE LEARN MORE Over 550 booths showcasing the latest dental products and technology.
