Objetivo: Apresentar uma orientação baseada em evidência para terapias pulpar não vitais de cárie profundas ou trauma em dentes deciduos. Métodos: Um grupo de trabalho da AAPD realizou uma revisão/análise sistemática para estudos não vitais de dentes deciduos resultantes de trauma ou cárie e utilizou a abordagem GRADE para avaliar o nível de certeza de evidência para recomendações clínicas. Resultados: O GRADE foi avaliado de nível alto à muito baixo. Comparando os dentes com/sem reabsorção radicular, o sucesso da pulpectomia foi melhor (p<0,001) naqueles sem reabsorção radicular pré-operatória. OZ/iodofórmio/HC (óxido de zinco + iodofórmio + hidróxido de cálcio; EndoflasTM) e OZE (óxido de zinco e eugenol) o sucesso da pulpectomia não diferiu do iodofórmio (iodofórmio + hidróxido de cálcio; VitapexTM, MetapexTM) (p= 0,55) após 18 meses; contudo, as taxas de sucesso de OZ/iodofórmio/HC e OZE permaneceram perto de 90% enquanto que o iodofórmio foi de 71% ou menos. As taxas de análise da rede mostraram que o OZ/iodofórmio/HC e OZE era melhor do que o iodofórmio. LERT foi melhor (p<0,001) do que a pulpectomia nos dentes com reabsorção radicular pré-operatória, mas os resultados da pulpectomia foram melhores (p= 0,.09) se as raízes estivessem intactas. A instrumentação rotatória dos canais radiculares foi significativamente mais rápida (p<0,001) do que manual, mas a qualidade do preenchimento não diferiu (p= 0.09) e ambos tiveram sucesso comparável. A análise de rede classificou OZ/iodofórmio/HC como o melhor, OZE segundo, e iodofórmio como o mais baixo aos 18 meses. As taxas de sucesso não foram influenciadas pelo método de obturação ou determinação do comprimento da raiz, tipo de dente, número de visitas, irrigantes, remoção da lama dentinária, ou tempo/tipo de restauração final. Conclusões: As taxas de sucesso da pulpectomia de 18 meses favoreceram pulpectomias com OZ/iodofórmio/HC e OZE sobre iodofórmio. O LERT demonstrou indicação limitada para dentes com raízes reabsorvidas e requer um acompanhamento assíduo.
