Functional Demands on the Cell Proliferative Activity of the Rat Periodontium Studied Autoradiographically

Abstract

Functional demands on the cell proliferative activity of the rat periodontium were studied autoradiographically with tritiated thymidine. Labeling indexes were assessed for fibroblasts, osteoblasts, and cementoblasts in the regions of the first molars of the maxilla and the mandible. Fibroblasts had the highest labeling index.
