True Pulp Stone
Pulp stones are not always free within the pulp. They may become embedded in secondary dentin as this material proliferates out into the pulp cavity. An embedded pulp stone (A) lies near the center of the field. There is some suggestion of dentinal tubules (B) radiating from the center of the stone, true or false, so it may be classified as a true pulp stone. Pulp stones may also be classified as free, attached, or embedded.
