RESUMO

Root canals of dogs premolar teeth were exposed to contamination and to the development of periapical inflammation during 45 days. Root canals were overinstrumented 2mm beyond the apical foramen using file number 60, and were underfilled by 2-3 mm of the roentgenographic apex. 90 days after endodontic treatment, healing and ingrowth of connective tissue into the root canal occured in 67.8% of the case s. These results suggest that the diameter of the apical forame and the intensity of the canal contamination are determinant factors for the periapical tissue repair in cases of pulpar necrosis
