GT status was classified as present, remnant, or non\u2010visualized. GT luminal diameters were measured in GT\u2010present teeth. Associations with age, sex, and unerupted canine depth were examined.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n GT remnants were observed in 42 teeth (13.4%). GTs were common at ages 9\u201311\u2009years, whereas non\u2010visualization predominated at \u2265\u200912\u2009years. The non\u2010visualized group was significantly older, while the remnant group showed greater unerupted canine depth. In threshold\u2010specific multivariable analyses accounting for within\u2010patient clustering, increasing age was associated with GT non\u2010visualization versus remnant\/present (OR\u2009=\u20091.10,\n p<\/jats:italic>\n \u2009=\u20090.039), and greater unerupted canine depth with non\u2010visualized\/remnant versus present (OR\u2009=\u20091.11,\n p<\/jats:italic>\n \u2009=\u20090.012). Shallower unerupted canine position was associated with larger GT luminal diameters.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The GT showed age\u2010associated radiological differences in unerupted maxillary canines. The remnant\u2010type GT may represent a distinct radiological appearance in patients aged \u2265\u20099\u2009years.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/ipd.70146","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T09:45:43Z","timestamp":1790588743000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Age\u2010Associated Radiological Characteristics of the Gubernaculum Tract in Unerupted Maxillary Canines: A Retrospective, Computed Tomography Study"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2830-1270","authenticated-orcid":false,"given":"Kozue","family":"Iwawaki\u2010Otsuka","sequence":"first","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4330-2984","authenticated-orcid":false,"given":"Masafumi","family":"Oda","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ikuko","family":"Nishida","sequence":"additional","affiliation":[{"name":"Division of Developmental Stomatognathic Function Science Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Division of Maxillofacial Surgery Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9089-6768","authenticated-orcid":false,"given":"Kazuya","family":"Haraguchi","sequence":"additional","affiliation":[{"name":"Division of Maxillofacial Surgery Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6288-1101","authenticated-orcid":false,"given":"Nao","family":"Wakasugi\u2010Sato","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinobu","family":"Matsumoto\u2010Takeda","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shun","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susumu","family":"Nishina","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6468-0939","authenticated-orcid":false,"given":"Yasuhiro","family":"Morimoto","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology Kyushu Dental University Kitakyushu Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,28]]},"reference":[{"key":"e_1_2_11_2_1","first-page":"300","article-title":"Histology and Function of the Dental Gubernacular Cord","volume":"41","author":"Carollo D.
