ANOMALIES OF THE CROWN
Study Notes
Dental Anomalies
- Fusion of two developing tooth germs into a single large tooth structure is characterized as Gemination.
- An attempt to make two teeth from a single enamel organ is characterized as Twinning.
- Teeth with elongated crown and apically displaced furcations, resulting in increased apical-occlusal height of the pulp chamber, are characterized as Taurodontism.
- A supplemental cusp arising from the cervico-lingual ridge or overdeveloped cingulum is characterized as Cusp of Carabelli.
- A cone-shaped tooth crown due to aplasia of the mesial and distal components of the tooth is characterized as Conical teeth.
- A tooth within a tooth or accentuation of the lingual pit is characterized as Dens in Dente.
- Note: Gemination and Twinning are often confused, but they are distinct anomalies. Gemination is the fusion of two developing tooth germs, while Twinning is an attempt to make two teeth from a single enamel organ.
