[Clinical and radiographic evaluation of deciduous molars with necrotic pulp treated with two concentrations of formocresol]. / Evaluación clínica y radiográfica de molares temporales con pulpas necróticas tratados con dos concentraciones de formocresol.

The purpose of this investigation was to evaluate clinically and radiographically primary molars with necrotic pulps treated with two different formocresol concentrations (full-strength formocresol and 20% dilution of formocresol). A total of 50 cases were evaluated at 3, 6 and 12 months after the treatment. There were not significant statistical differences in the results obtained between both concentrations; therefore it can be conclude that the 20% dilution of formocresol represent a satisfactory treatment for primary molars with necrotic pulps. Due to this findings is possible to assure that this procedure in easy, reliable and cheap; and also is possible to apply to all ages and socioeconomic label.
