Study and evaluation of the gubernacular canal by means of cone beam computed tomography.

Abstract

The aims of this review of the literature were to conceptualize the gubernacular canal, by an approach to its function, importance and characteristics of its image in Cone Beam Computed Tomography. The bibliographic survey of scientific articles was conducted in the following databases: PubMed, Bireme, Scielo and Google Scholar. The gubernacular canal, which carries the gubernacular cord within it, is an anatomic structure that starts in the dental follicle and goes through to the alveolar bone crest behind the deciduous tooth. This set appears to play an important role in the tooth eruption process, serving as guide to the permanent tooth in the eruptive trajectory, in addition to being a possible factor in the etiology of odontogenic tumors. Therefore, knowledge about and visualization of this canal in terminological exams such as Cone Beam Computed Tomography are relevant in dental clinical practice to help with the diagnosis of tumors and abnormalities in the eruptive process, thus enabling early intervention when necessary.
