hypercémentose

Hypercementosis is an idiopathic, non-neoplastic condition characterized by the excessive buildup of normal cementum (calcified tissue) on the roots of one or more teeth. A thicker layer of cementum can give the tooth an enlarged appearance, mainly occurring at the apex or apices of the tooth. The cellular cementum functions at the bottom half of the tooth roots which contain cementocytes that anchor the tooth into the jaw socket, protect the tooth's pulp, and repair external root resorption.

==Signs and symptoms== thumb|Location of where excess cementum may appear It is experienced as an uncomfortable sensation in the tooth, followed by an aching pain. Excess amounts of cementum may cause pressure on periodontal ligaments and adjacent teeth. The teeth affected may present as asymptomatic. It may be shown on radiographs as a radiopaque (or lighter) mass at each root apex to confirm the diagnosis.
