RESUMO

The objective of this work was to analysis radiographically the bony loss in the furcation region, in dog s teeth, intentionally perforated and contaminated with oral fluids, about the employment of several sealer materiaIs. It was utilized 6 adult dogs, weighing from 9 to 15 kilograms, females and the indefmite race. Perforations were produced in the furcation s region from the 2°, 3°, and 4° inferior right and left premolars, and they stayed exposed to the oral cavity for a period of 30 days. Afterwards this interview of time, was found the formation of furcation s lesions by periapical radiography, the teeth were cleaned and treated in accord to the experimental groups division. The perforation of the 2°, 3°, and 4° premolars were fulfilled with hemihydrated calcium sulfate and sealed with gutta-percha, IRM and Z-100 resin, respectively, and just the right side teeth s perforation were decontaminated with 2% gel chlorhexidine. Padronized radiographic were made in the beginning of the experiment, 30 days after the exposition of the perforations to the oral cavity and 180 days after the employment of the sealer materiaIs. The images were transported to the computer and the areas of the bony loss were measured utilizing the "ImageLab" programo The results were analyzed statically andthe images demonstrated minor loss of bony structure when the perforation were sealed with Z-100 resin, in comparation to IRM and gutta-percha, demonstrating minor bony loss with the utilization of 2% gel chlorhexidine for the decontamination
