Nickel-titanium (NiTi) instruments have enhanced canal shaping by offering flexibility and improved performance, particularly in complex anatomies. WaveOne Gold (WOG), TruNatomy (TN), and ProTaper Ultimate (PU) are widely used NiTi systems with distinct designs, properties, and kinematics, but limited data exist comparing their canal transportation and centering ability, especially for PU. The objective of this studywas to assess and compare the shaping performance of WOG, TN, and PU in the mesiobuccal (MB) canals of maxillary molars. The null hypothesis was that no significant differences would be found in canal transportation or centering ability.Methods: Forty-two extracted human maxillary molars with curved MB canals (25\u00b0\u201340\u00b0) were allocated into three groups (n=14) and instrumented using WOG, TN, or PU systems. Microcomputed tomography (\u03bcCT) scans were acquired before and after instrumentation to assess both centering ability and canal transportation at distances of 3 mm, 5 mm, and 7 mm from the apical foramen. A one-way ANOVA and Tukey\u2019s post hoc test were used for data analysis (p<\/jats:p>","DOI":"10.14744\/eej.2025.45822","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T11:43:10Z","timestamp":1764848590000},"page":"542-552","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of the Canal Transportation and Centering Ability of TruNatomy, WaveOne Gold and Protaper Ultimate: An Ex Vivo Study in Human Maxillary Molars"],"prefix":"10.65717","volume":"10","author":[{"given":"Gilberto","family":"Ribeiro","sequence":"first","affiliation":[]},{"given":"Victor","family":"Martin","sequence":"additional","affiliation":[]},{"given":"Cl\u00e1udia","family":"Rodrigues","sequence":"additional","affiliation":[]},{"given":"Pedro","family":"Gomes","sequence":"additional","affiliation":[]}],"member":"55248","published-online":{"date-parts":[[2025,11,19]]},"container-title":["European Endodontic Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/359\/359","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/download\/359\/359","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T12:16:29Z","timestamp":1769084189000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.eurendodj.com\/index.php\/pub\/article\/view\/359"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,19]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2025,11,19]]}},"URL":"https:\/\/doi.org\/10.14744\/eej.2025.45822","relation":{},"ISSN":["2548-0839"],"issn-type":[{"value":"2548-0839","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11,19]]}}}
