Uma das principais vantagens do uso do sistema rotatório contínuo em pulpectomias é a redução do tempo de instrumentação. Apresentamos o caso de uma menina de 3 anos e 11 meses que, ao exame clínico intraoral, apresentava uma lesão cariosa extensa e profunda com envolvimento pulpar do dente 85. Radiograficamente, foi observada uma imagem radiolúcida oclusal com claro envolvimento pulpar, compatível com necrose pulpar e periodontite apical crônica. A pulpectomia foi realizada com o sistema rotatório NiTi Race® Evo #25/06 a 500 rpm e um torque de 2,1 Ncm. No controle clínico, os tecidos gengivais circundantes estavam em boas condições. Radiograficamente, não houve evidência de reabsorção radicular ou sinais de infecção, e a regeneração óssea foi observada no nível da furca. O sistema rotativo mostrou-se eficiente tanto na modelagem quanto na obturação dos canais, reduzindo o tempo de instrumentação.
