False Pulp Stone

In the center of the field, lying within the pulp (A), is a large spherical mass staining similar to the dentin (B) above. This is a pulp stone (C) or denticle. Pulp stones are mineralized masses that arise in the pulp and are classified as true or false. True pulp stones appear to be composed of dentin in that they exhibit dentinal tubules. False pulp stones do not appear to be produced by odontoblasts and are thought to originate from a mineralized nucleus in the pulp and grow appositionally. True pulp stones are rare. Based on its morphology, this is a false pulp stone.



A - pulp
