Dens invaginatus: case report

O dente invaginado e uma das alteracoes de desenvolvimento que mais incide sobre os elementos dentarios, podendo acometer qualquer dente existente na cavidade oral, inclusive deciduos e supranumerarios. Consiste em uma invaginacao da superficie da coroa, que ocorre na odontogenese, que penetra no interior da cavidade pulpar dos elementos dentarios envolvidos, podendo chegar, em algumas situacoes, a regiao apical. O incisivo lateral superior permanente e o que apresenta maior envolvimento. Por apresentar uma anatomia complexa e variavel, quando diagnosticado, o dente pode apresentar necrose pulpar e rizogenese incompleta, o que torna a sua manutencao muitas vezes de dificil solucao. Em 1957, Oehlers classificou-os, conforme sua complexidade, em tipos I, II e III. Foi realizada uma revisao da literatura e descrito o tratamento de um incisivo medial superior com invaginacao tipo II, cuja estrutura invaginada se desprendeu devido as varias instrumentacoes durante as trocas de curativo, o que facilitou sua obturacao. Pudemos concluir com este caso a viabilidade, atraves de diversos metodos, da remocao da porcao invaginada no tratamento de dentes invaginados tipo II.
