Pulpal Sclerosis


Definition: Diffuse calcifications in the pulp chamber and/or root canal.  This is also referred to as calcerous degeneration.

Radiographic Features:

Location: Any pulp chamber and/or root canal.

Edge: Well-localized.

Shape: Follows the shape of the pulp chamber and/or root canal.

Internal: Radiopaque.

Other: Does not alter the shape of the pulp chamber and/or root canal.  These calcifications conform to the shape of the pulp chamber and/or root canal.

Number: Multiple entities exist in a single tooth, may affect multiple teeth throughout the mouth.

TIP: Small pulp stones and pulpal sclerosis in a pulp chamber may be difficult to determine the difference between.  Look to see if the pulp chamber shape has been enlarged indicating a pulp stone.  If the pulp chamber shape has not been enlarged, pulpal sclerosis is more likely.  Both are incidental findings and treatment is not necessary on a vital asymptomatic tooth.
