Gubernacular cord and canal – does these anatomical structures play a role in dental eruption?

Resumo

The gubernacular cord is an original structure of the
dental lamina, which undergoes apoptosis and their remnants were
organized in the form of epithelial islets and strands that lined up,
leaving the reduced epithelium of the enamel organ towards the oral
mucosa. This structure is located within the gubernacular canal,
which can be identified as a small opening in the alveolar region
of the lingual or palatal surface of the deciduous teeth. Objective:
To conceptualize, identify and assess the possible contribution of
the gubernacular cord and canal in the process of tooth eruption.
Literature review: A review of literature on Pubmed, Medline and
Bireme databases, without datum restriction. Little amount of scientific
articles were found, and only 14 studies were identified. The authors
addressed the matter succinctly, with little information about these
structures, which can play an important role in the process of tooth
eruption. Conclusion: The gubernacular cord and canal are anatomical
structures located in the alveolar bone crest of the maxilla or mandible, behind the deciduous teeth. These structures appear to exhibit the
ability to aid the eruption path of the permanent teeth successors.
Despite being a relevant subject, few professionals know this structure
and its possible role in the process of tooth eruption.
