Abstract

Removal of the proliferating base of the rat incisor did not influence the rate of eruption which responded to changes in impediment to eruption in a fashion similar to that for control teeth. It is the periodontal ligament rather than the proliferating cells that is responsible for tooth eruption. The elements of the periodontal ligament apparently responsible for tooth movement are the mature fibroblasts.
