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.

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
