Concrescence is a condition of teeth where the cementum overlying the roots of at least two teeth join together. It usually involves only two teeth. The most commonly involved teeth are upper second and third molars. The prevalence rate is 0.04%.
This condition arises as the result of traumatic injury or overcrowding of teeth. True concrescence occurs during root formation phase, whereas acquired concrescence occurs after the radicular phase of development is complete.
It is experienced as an uncomfortable sensation in the tooth, followed by an aching pain.
It may be noted on radiographs as a radiopaque (or lighter) mass at each root apex.
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, which mainly occurs at the apex or apices of the tooth.
