Abstract

The nature of epithelium and the remarkable facility with which it aggressively covers granulation tissue, suggests that removal of the sulcular epithelium surrounding the extraction wound of a tooth to be replanted could promote reattachment of the periodontal tissues at a more nearly ideal coronal level. To investigate this hypothesis twenty mature teeth in five mongrel dogs were experimentally replanted. One half of them were replanted in alveoli around which the crevicular epithelium had been removed, the remaining teeth without creviculoectomy acting as controls. Animals were euthanized at one, two, three, five, and sixteen weeks. After clinical evaluation of the attachment and mobility, histological sections were made and evaluated. No teeth were lost in the study and epithelial migration was not remarkable. Root resorption was common and severe.

This study indicates that reattachment of the periodontal ligament and epithelial attachment at a more nearly ideal level can be enhanced by creviculoectomy. However, the evidence does not support a conclusion that sulcular epithelial migration constitutes a major hazard, comparable to root resorption, to successful replantation of teeth.
