[Studies on the surgical approach in vital pulp excision in relation to the root canal cross section]

The authors examined in 38 teeth the condition of the pulp stump after vital extirpation of the pulp in relation to the cross-section of the root canal. They found that the wound conditions could not be evaluated in 17 teeth as there was no pulp stump in the apical region. Relatively favourable conditions were seen in 11 teeth, which was achieved only in case of circular or oval cross-section of the root canal. These findings permit the conclusion that the state of the pulp stump after vital extirpation depends upon the anatomical conditions and the accuracy of the mechanical manipulation.
