Resumo
Os autores descrevem o tratamento endodóntico de dentes permanentes jovens com ápices abertos e polpas necrosadas em pacientes com idade variando entre 8 anos e 6 meses e 9 anos e 11 meses. A técnica utilizada para o tratamento dos dentes com necrose pulpar, rafzes incompletas e ápices abertos baseou-se na colocação de pasta contendo hidróxido de cálcio como curativo de demora (curativo expectante) através de procedimento mediato, com renovação a cada três meses e observação clinica e radiográfica do fechamento apical. Após o aparente fechamento apical os canais foram obturados levando-se hidróxido de cálcio na porção apical seguindo-se a obturação convencional definitiva com cones de guta-percha e cimento para canal. Apreservação foi feita periodicamente e os casos relatados já se encontram com mais de 2 anos.

Abstract
Calcium hydroxide paste was used as a temporary dressing and the renewal was done each three months in the root canal treatment of immature teeth with operi apex and necrotic pulps. Clinical and radiographic controls were made to observe foraminal closure. After that the root canais were filled, employing the conventional technique wíth gutta-percha cones and zinc oxide eugenol cements. The calcium hydroxide paste was applied in the apical region before the root canal filling. The follow-up was done periodically and the cases have more than two years of control.
