Resumo
Objetivo: Compreender a anatomia dos canais radiculares é essencial para o sucesso endodôntico. Este estudo analisou a morfologia dos canais radiculares de dentes anteriores maxilares e mandibulares em uma subpopulação brasileira por meio de tomografia computadorizada de feixe cônico (TCFC). Métodos: Estudo transversal retrospectivo com 1.975 imagens de TCFC de dentes anteriores de 268 pacientes. As imagens foram avaliadas no software XoranCat quanto ao número de raízes e à configuração dos canais, segundo a classificação de Vertucci. Utilizou-se o teste do qui-quadrado (p < 0.05). Resultados: A maioria dos dentes (99,9%) apresentou uma única raiz; apenas 0,1% tinham duas. A configuração mais prevalente foi o Tipo I de Vertucci (95,8%), seguida pelo Tipo III (2,8%) e Tipo II (1%). Os Tipos VI e VII foram raros (0,3% e 0,1%). Não houve associação significativa com o gênero (p > 0.05). Conclusão: Os dentes anteriores apresentaram morfologia simples, com predominância de canais e raízes únicas. No entanto, variações anatômicas podem ocorrer, exigindo atenção do cirurgião-dentista para garantir a localização adequada dos canais e o sucesso do tratamento endodôntico.
