Introdução: A odontometria constitui uma etapa fundamental para o sucesso do tratamento endodôntico, atualmente existem diversos métodos para a obtenção dessa medida. Objetivo: Realizar uma comparação entre o comprimento real do dente mensurado pelas técnicas de Ingle e eletrônica, utilizando os localizadores apicais eletrônicos Root ZX e Propex. Material e método: Foram selecionados 24 pacientes para participar do estudo, obtendo-se um grupo de vinte e quatro dentes unirradiculares, com rizogênese completa e diagnóstico de necrose pulpar, para realização das mensurações. Após o isolamento, acesso e neutralização do conteúdo séptico do canal radicular, todos os dentes foram submetidos às três técnicas de odontometria, obtendo-se assim o comprimento real do dente. Os dados foram submetidos a uma análise estatística descritiva. Após verificação da normalidade dos dados mediante emprego do teste de Shapiro-Wilk, realizou-se o teste ANOVA o qual demonstrou efeito significativo do tipo de método utilizado para obter os valores do comprimento real do dente. Resultados: A comparação par a par com ajuste de Bonferroni revelou que a média dos valores do comprimento real do dente obtidos por meio da técnica radiográfica de Ingle e do localizador Root ZX foram diferentes de maneira significativa da média dos valores obtidos usando o localizador Propex. Conclusão: Com base nos dados apresentados, conclui-se que o localizador apical Propex apresentou resultados diferentes dos obtidos pela técnica de Ingle e pelo localizador Root ZX.Descritores : Odontometria; Cavidade Pulpar; Ápice Dentário.ReferênciasLin LM, Skribner JE, Gaengler P.
