Resumo
A entidade nosológica dens invaginatus é uma anomalia congénita e do desenvolvimento do dente, rara, que se caracteriza pelo facto dos dentes adquirirem forma e tamanho inusuais, consubstanciados numa aparência típica de um "dente dentro de outro dente". Nestes dentes, é muito comum observarem-se comorbilidades como pulpite, necrose pulpar, ou inflamação periapical. Com este trabalho, pretendemos descrever dois casos clínicos de dens invaginatus, observados em cães de diferentes raças e idades, consultados no Hospital Ars Veterinária (Barcelona, Espanha). Ambos os casos clínicos foram diagnosticados com recurso à utilização de radiografia dentária intraoral e ao exame histopatológico das peças dentárias extraídas. A abordagem terapêutica foi distinta nos dois casos descritos, tendo incluído a realização de extração dentária e/ou de tratamento endodôntico conservador, nomeadamente de pulpectomia total. Pretende-se que este trabalho contribua para auxiliar os médicos veterinários a melhorar o seu desempenho, no que concerne ao diagnóstico e ao tratamento desta alteração do desenvolvimento estrutural do dente, dada a escassez de literatura científica relacionada com o tema, assim como transmitir os pontos-chave das outras doenças congénitas, com maior relevância, que se podem encontrar na prática clínica.
The nosological entity dens invaginatus is a rare anomaly of tooth development that is characterized by the fact that the teeth acquire a rare shape and size, with the typical appearance of a "tooth within a tooth". In these teeth, it is very common to observe co-morbidities such as pulpitis, periapical inflammation and/or pulp necrosis. The aim of this report is to describe two clinical cases of dens invaginatus affecting several teeth, including canines, premolars and molars in dogs of different breeds and different ages, attend at Hospital Ars Veterinária (Barcelona, Spain). Both cases were diagnosed using intraoral radiography, and further histopathological analysis of the extracted teeth were performed to confirm this condition. The therapeutic approach was distinct in the two studied dogs, involving dental extraction and endodontic treatment, namely total pulpectomy. This report aims to help veterinarians improving their performance regarding the diagnosis and treatment of this alteration in the structural development of the tooth, given the scarcity of scientific literature related to the subject.
