Resumo
Este trabalho foi desenvolvido com o objetivo de observar se o acréscimo de iodofórmio, ao cimento obturador de canal Sealapex, altera suas propriedades biológicas. Para tanto, dentes de cães, submetidos à pulpectomia, foram sobre-instrumentados e a seguir obturados com Sealapex acrescido ou não de iodofórmio, em duas diferentes proporções. Os resultados histológicos, analisados 6 meses após o tratamento, mostraram-se semelhantes entre os grupos experimentais onde o Sealapex recebeu ou não o acréscimo de iodofórmio.

Abstract
Some endodontists use iodoform in Sealapex in order to rend it more radiopac. This procedure is empiric and for this reason we decided to observe, histologically, if the iodoform introduces some modification in the biological properties of Sealapex. Thirty root canals of dog's teeth were overinstrumented and filled, by lateral condensation technique, with gutta percha points and Sealapex, with or without iodoform. The iodoform was added in two differente proportions: 30 mg or 112 mg for one centimeter of the base and one centimeter of the catalyst of Sealapex. The pieces were removed for histological studies, 6 months after the treatment. The histological results showed that Sealapex encourages apical closure by cementum deposition and that the addition of iodoform does not change that biological property.
