LATERAL CONDENSATION IN TREATMENT OF PULPITIS AND PULP GANGRENE - STUDIES ON DOG CANINE TEETH

The clinical investigation, carried out in dogs, comprises selected ca ses of chronic pulpitis and pulpal gangrene of canine teeth resulting from injuries. A group of 20 teeth (group 1) underwent extirpation of pulp, as well as elaboration of a root canal and its tilling with Endo methasone paste, under general anaesthesia during a one-stage procedur e. The second group of 20 teeth differed from the first in an addition al concentration of the paste, due to an introduction of gutta-percha points (lateral condensation). This sealing modification proved to dim inish the risk of leaving empty spaces after pulp removal in the pulpi tis state. However, in teeth where gangrenous pulp extirpation was per formed, lateral condensation was endangered by pushing the paste throu gh beyond the apex. Both anomalies were likely to predispose to the de velopment of apical periodontitis.
