Abstract
A detailed description of the problem of traumatic perforation which
may appear as a complication in endodontic treatment is given. The goal of the work was to determine the effect of medicaments, cavit and diaket, on the perforated tooth and its environment and to compare it to the control group in which traumatic perforation remain untreated. The histological analysis was performed on 64 albino rats and 192 histological preparations were made. All the changes occurring in the tissue surrounding the traumatic tooth perforation were observed: hyperemia, hemorrhage, the type end the quantity of the cells appearing in the inflammatory infiltrate and the development of granulation tissue. The changes in pathohistologiical findings obtained in animals sacrificed at different time intervals were followed up (after 4, 20, 43 and 63 days). The results of the investigation show that both cavit and diaket are suitable medicaments for the closure of the traumatic perforation and that cavit displays certain advantages in relation to diaket. It is more easily adapted to perforated area, it does not run into the canal entrances as diaket and lit supports better secretion which is more or less expressed in the area of traumatic perforation.
