CANAL GUBERNACULAR EM DENTES SUPRANUMERÁRIOS: RELATO DE DOIS CASOS

Abstract

Rodrigues, NMP. Gubernacular Canal in Supernumerary Teeth: Case Report of Two Cases. Campo Grande; 2024. [Trabalho de conclusão de curso – Universidade Federal de Mato Grosso do Sul]. Human facial development is a fundamental process that begins in the early weeks of gestation, directly influencing the formation of the oral cavity and the dental eruption process. Among the structures that develop, the gubernacular canal plays an important role in the eruptive process by facilitating communication between dental germs and the oral . Current literature primarily reports its presence in incisors and molars, with its visualization in supernumerary teeth being rare. Thus, this study aimed to report two cases in which gubernacular canals were identified in supernumerary teeth using cone-beam computed tomography. In the first case, a 39-year-old female patient presented a supernumerary tooth in close relation to tooth 44, with complete root development and the presence of the gubernacular canal. In the second case, a 16- year-old male patient exhibited the same structure associated with a supernumerary tooth with incomplete root development near tooth 35. In both cases, cone-beam computed tomography allowed detailed visualization of the canal, underscoring its effectiveness in assessing anatomical relationships in three dimensions. This indicates that, although the presence of the gubernacular canal is typically documented in children and adolescents during the dental eruption period, it can also be observed in older patients, including those with supernumerary teeth. It is concluded that case studies of gubernacular canals in supernumerary teeth, though rare, may broaden the understanding of dental anatomy and the clinical implications of its presence, even in atypical conditions.
