The possibility that pathologic conditions in the dental pulp or periodontal ligament cause changes in the other structure was explored. This was undertaken by creating pulpal and periodontal lesions in different areas in white rats and examining the adjacent pulp or periodontium after varying intervals of time. The data seem to substantiate the interrelationship of these two organs. © 1973.
