RESUMO

The purpose of the present study was to evaluate the histological and radiological response to two. materials used as a matrix under a zinc oxide-eugenol cement used as a sealant in the repair of furcation perforations in experimental animals. After anesthesia, rootcanal treatment of canaIs with zinc oxide-eugenol cement, furcal perforations were made in 24 lower premolar (p3 and P4) teeth of mongrel dogs, with L.N. burs. The perforated teeth were random1y divided into 3 groups of 8 teeth: Group I - perforations sealed with Endomethasone; Group II - perforations sealed with Endomethasone after the placement of an internal matrix of calcium hydroxide; Group m - perforations sealed with Endomethasone after the placement of an internal matrix of calcium sulfate. Pulp chamber of all teeth were filled with composite resin after acid etching and application of dentinal adhesive. Animals were sacrificed after 14 and 90 days. The teeth and surrounding structures were processed for light microscopy. The conclusion of this study is that a placement of a barrier at the pulp chamber aspect of a furcation perforation did not result in superior healing, compared with the use of zinc oxide-eugenol cement alone and complete healing of furcation perforations with hard tissue was not observed
