Principles and practice of operative dentistry . e areas of absorption upon one part of theroot and large additions of new tissue upon another part may be observedin the same specimen.

When such teeth are extracted the pericementum is found to be muchthickened and abnormally vascular. Sometimes there will be foundadherent to the irregular surface of the new-formed cementum certainflesh-like masses which remind one of the absorbent organ found attachedto exuviating deciduous teeth. Examined microscopically, the new-formed cementum is shown to. (^ementum Dentin
