Cone beam computed tomography and multi-detector computed tomography have recently been used to visualize the GT, with the results indicating that this structure might be related to the normal eruption of teeth. By contrast, curved and\/or constricted GTs may lead to abnormal tooth eruption. In addition, complex odontomas have been reported from within the GT or dental sac of unerupted permanent teeth. If an odontoma occurs within the GT, the tooth will not erupt normally. Moreover, the imaging characteristics of the GT from the top of the odontogenic mass to the alveolar crest are extremely useful for making a differential pathological diagnosis and for differentiating between odontogenic and non-odontogenic masses. Therefore, radiological studies on the GT have been attracting increasing attention. Given this background, the present review aims to clarify the imaging characteristics and review recent studies on the GT considering the importance of the research.<\/jats:p>","DOI":"10.3390\/jcm10143051","type":"journal-article","created":{"date-parts":[[2021,7,9]],"date-time":"2021-07-09T10:50:38Z","timestamp":1625827838000},"page":"3051","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Overview of Radiological Studies on Visualization of Gubernaculum Tracts of Permanent Teeth"],"prefix":"10.3390","volume":"10","author":[{"given":"Masafumi","family":"Oda","sequence":"first","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ikuko","family":"Nishida","sequence":"additional","affiliation":[{"name":"Division of Developmental Stomatognathic Function Science, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manabu","family":"Habu","sequence":"additional","affiliation":[{"name":"Division of Maxillofacial Surgery, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Division of Maxillofacial Surgery, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroki","family":"Tsurushima","sequence":"additional","affiliation":[{"name":"Division of Oral Medicine, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taishi","family":"Otani","sequence":"additional","affiliation":[{"name":"Division of Oral Medicine, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daigo","family":"Yoshiga","sequence":"additional","affiliation":[{"name":"Division of Oral Medicine, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsura","family":"Saeki","sequence":"additional","affiliation":[{"name":"Division of Developmental Stomatognathic Function Science, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsurou","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nao","family":"Wakasugi-Sato","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinobu","family":"Matsumoto-Takeda","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yutaro","family":"Nagasaki","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ikuya","family":"Miyamoto","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery, Iwate Medical University, Iwate 028-3694, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinji","family":"Kito","sequence":"additional","affiliation":[{"name":"Division of Dental Radiology, Meikai University School of Dentistry, Saitama 350-0283, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaaki","family":"Sasaguri","sequence":"additional","affiliation":[{"name":"Division of Maxillofacial Surgery, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasuhiro","family":"Morimoto","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology, Kyushu Dental University, Kitakyushu 803-8580, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1111\/j.1600-0714.1980.tb00377.x","article-title":"Tooth eruption: Evidence for the central role of the dental follicle","volume":"9","author":"Cahill","year":"1980","journal-title":"J.
