Currently, there is no data available on the canal shaping abilities of BlueShaper and DC Taper instruments.<\/p>\n<h2>Methodology<\/h2>\n<p>Sixty-four single-rooted mandibular premolars were matched based on similar root canal morphologic features as determined by (micro-CT) and randomly assigned to 1 of 4 experimental groups (n = 16) according to the instrument system used: BlueShaper, TruNatomy, DC Taper and HyFlex EDM One File. Changes in the root canal surface and volume, remaining dentine thickness, and number of prepared areas were assessed.<\/p>\n<h2>Results<\/h2>\n<p>No significant differences were found amongst the four instrument systems for the parameters evaluated (p &gt; .05). There was a significant reduction in the number of unprepared areas and the remaining dentine thickness after each increase in size of the instruments tested (p &lt; .05).<\/p>\n<h2>Conclusions<\/h2>\n<p>The four instrument systems perform similarly in long oval root canals. Although none could prepare all canal walls, larger preparations incorporated significantly more surfaces in the final shape.<\/p>\n<h2>Keywords<\/h2>\n<p>3D surface scanning, computational fluid dynamics, endodontics, mechanical tests, reciprocating instruments<\/p>\n","protected":false},"template":"","class_list":["post-2416","zarc_sci_article","type-zarc_sci_article","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Multimethod analysis of large- and low-tapered single file reciprocating instruments: Design, metallurgy, mechanical performance, and irrigation flow - Zarc<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Multimethod analysis of large- and low-tapered single file reciprocating instruments: Design, metallurgy, mechanical performance, and irrigation flow - Zarc\" \/>\n<meta property=\"og:description\" content=\"Abstract Aim This study evaluated and compared the shaping ability of four rotary instrument systems in long\u2013oval root canals using microcomputed tomographic (micro-CT) evaluation.
