Resumo
O objetivo deste trabalho foi analisar histologicamente a influência da remoção da membrana periodontal, utilizando solução de hipoclorito de sódio a 5% neutralizada pelo ácido cítrico a 10%, e a conservação por 60 minutos em soro fisiológico em dentes de cães reimplantados, após a remoção da polpa e sua substituição por hidróxido de cálcio. Os autores observaram, em ambos os grupos, reinserção epitelial abaixo da junção cemento-esmalte. Nos dentes tratados com solução de hipoclorito de sódio notou-se reinserção de fibras periodontais, menor ocorrência de anquilose e de reabsorção do que no grupo de dentes tratados com soro fisiológico.

Abstract
The study was designed in order to verify if the maintenance of vital periodontal remnants on the surface root is essential for the healing process of replanted teeth. Dog teeth were extracted and submitted to pulp extirpation and root canal filling with a calcium hydroxide paste. Then, one group of teeth was immersed in saline solution for one hour before the replantation (control group). Teeth of the experimental group were immersed in 5% sodium hypochlorite solution for one hour followed immersion in 10% acid citric for one minute, and brief wash in saline before to be reimplanted. The histological analysis showed that the epithelial attachment was below the cement-enamel junction, for both groups. Nevertheless, teeth treated by hypochlorite and citric-acid (the experimental group) showed new functionally oriented periodontal fibers, newly apposed cement and bone and was related to less frequent occurrence of root ankylosis and resorption than the contrai specimens.
