Human premolars were obtained for sectioning following rapid maxillary expansion to observe the pattern of resorption and cementum deposition. Some sections were demineralized and examined by light microscopy, while the root surface of adjacent sections were observed in the scanning electron microscope. The pattern of repair by cementum was noted and found to differ from normal cementum. In addition, the vascular pattern of the periodontal ligament in rat molars has been studied by methacrylate perfusion techniques. The vasculature of the inter-radicular area differed from that over the remaining root surface because of the presence of a dense plexus of large venous vessels. It is considered that there may be a relationship between vascular architecture and the processes of cementum deposition and root resorption. [ABSTRACT FROM AUTHOR] |
