tooth implant procedures

Gemination occurs when a developing tooth incompletely splits into the formation of two teeth. Fusion is the union of two adjacent teeth during development. Concrescence is the fusion of two separate teeth only in their cementum. Accessory cusps are additional cusps on a tooth and may manifest as a Talon cusp, Cusp of Carabelli, or Dens evaginatus. Dens invaginatus, also called Dens in dente, is a deep invagination in a tooth causing the appearance of a tooth within a tooth. Ectopic enamel is enamel found in an unusual location, such as the root of a tooth. Taurodontism is a condition where the body of the tooth and pulp chamber is enlarged, and is associated with Klinefelter syndrome, Tricho-dento-osseous syndrome, Triple X syndrome, and XYY syndrome.[70] Hypercementosis is excessive formation of cementum, which may result from trauma, inflammation, acromegaly, rheumatic fever, and Paget's disease of bone.[70] A dilaceration is a bend in the root which may have been caused by trauma to the tooth during formation. Supernumerary roots is the presence of a greater number of roots on a tooth than expected.
