In the present study, an attempt was made to improve the possibilities for rapid revascularization and original pulp tissue survival in replanted and autotransplanted mature dog teeth by increasing the contact area between the pulp and the vascularized periradicular tissues. In 12 teeth, the root tip was resected and 3 additional nutritional canals were prepared in the apical 1/3 of the root at the time of the operation. Another 12 teeth were replanted or autotransplanted with intact roots. After an observation time of 120 days, the teeth were studied with microangiographic and histologic techniques. 11 of the teeth that were replanted or autotransplanted with intact roots showed total pulpal necrosis. Partial or total pulpal revascularization and repair was seen in all apicoectomized teeth with nutritional canals. The revascularized area of the pulp was somewhat larger in the replanted compared to the autotransplanted group of teeth. Signs of survival of the original pulp tissue were not seen. A comparison of the findings with those of previous studies on replanted and autotransplanted teeth with apicoectomized roots but without additional canals shows that the revascularization of the pulp did not proceed more rapidly in the apicoectomized teeth in the present study, although the contact area between the pulp and the periradicular tissues was enlarged through the preparation of the 3 artificial nutritional canals.
