Dens invaginatus is a developmental variation resulting from an alteration in the
normal growth pattern of the dental papilla. Synonyms of this disturbance include
dens in dente, invaginated odontome, tooth inclusion, and dentoid in dente. Radiographically,
it is observed as infolding of a radiopaque ribbon-like structure, with equal density
as enamel, extending from the cingulum into the root canal and sometimes reaching
the root apex, assigning the appearance of a small tooth within the coronal pulp cavity.
This article presents 2 case reports. The first describes an 8-year-old girl with
dens invaginatus in a mesiodens; the second report describes a 16-year-old boy presenting
with 2 mesiodens, both associated with dens invaginatus.
