This topology image reveals the following structural information: The dentin and cementum are clearly delineated. There is never any indication of a space between the two tissues, and the collagen fibrils do not cross the dentinocementum junction. The cemental surface is studded with projections of varying size. The small conical projections are associated with individual periodontal fibrils. The fibrils are embedded in the cementum. They may be traced inward for a variable distance from the cemental surface. Near the surface they tend to be parallel and to continue in the orientation of their insertion. |
