Dens Invaginatus
Dens Invaginatus can occur in deciduous or in permanent teeth. The coronal portion of the tooth folds inward and typically becomes non-vital. The condition is also called "dens in dente" or a tooth within a tooth. Non-vital teeth need to be treated by dental extraction or by root canal therapy.
