Pulp stones (also denticles or endoliths)[1] are nodular, calcified masses appearing in either or both the coronal and root portion of the pulp organ in teeth. Pulp stones are not painful unless they impinge on nerves.

They are classified:[2]

A) On the basis of structure
1) True pulp stones: formed of dentin by odontoblasts
2) False pulp stones: formed by mineralization of degenerating pulp cells, often in a concentric pattern
B) On the basis of location
1) Free: entirely surrounded by pulp tissue
2) Adherent: partly fused with dentin
3) Embedded: entirely surrounded by dentin
