| Sumario: | The gubernacular cord is a connective tissue structure that joins the dental follicle to the gingiva. It is surrounded by a bony canal called the gubernacular canal and it is believed to guide tooth eruption. Detection of the gubernacular canal on conventional radiographs is difficult because it is very thin and has a lingual location to the temporary tooth, so it overlaps it. The identification and location of the gubernacular canal in relation to the dental follicle and the alveolar ridge are valuable data to rule out eruption anomalies and pathologies of odontogenic origin. The aim of the present study was to evaluate the characteristics of the gubernacular canal by means of cone beam computed tomography in a series of cases. In the included upper canines, the gubernacular canal was observed as a thin corticalized hypodense canal, with a short course, adherent to the follicle in its cervical and proximal contour, with a lingual opening at the alveolar ridge. Due to the horizontal and basal position of the lower canines, the gubernacular canal showed an extensive oblique path from its cervical and proximal attachment to the follicle to the lingual portion of the alveolar ridge. In the four lower third molars in intraosseous evolution, the gubernacular canal showed a short, quadrangular-shaped path, centrally located in the dental follicle and the alveolar ridge. It can be concluded that the appearance of the gubernacular canal varies according to the degree of inclusion and development of the tooth. Cone beam computed tomography allows precise characterization of its morphology and trajectory |
