Intraorally a small swelling shaped like an unerupted tooth
was visible on right retromolar region in contact with the distal surface of the first molar where the second and third molars were missing.
They develop around the crown of an unerupted tooth
by expansion of the follicle when fluid is collected or a space is formed between the reduced enamel epithelium and the enamel of an impacted tooth.
It may be associated with unerupted tooth
, dentigerous cyst or normal tooth.
They develop within the normal dental follicle around an unerupted tooth
as a result of fluid accumulation between the follicular epithelium and the crown of the tooth.
Dentigerous cyst usually arises from the follicle around an unerupted tooth
Computed tomography (CT) demonstrated (1) a bony mass that was occupying the maxillary antrum, (2) an unerupted tooth
just anterior to the mass, and (3) a patent maxillary sinus ostium (figure 1).
1) Unicystic ameloblastoma has become established as a distinct clinicopathological entity on the general basis of its unicystic radiographic appearance, histologic findings, association with an unerupted tooth
, occurrence in the mandible of younger patients, and a recurrence rate after conservative surgical treatment lower than that of its conventional counterpart.
In radiographs, the DC appears as a well-defined unilocular radiolucency associated with the crown of an unerupted tooth
A new, accurate and fast digital method to predict unerupted tooth
A number of cases suggest surgical exposure of the unerupted tooth
to restore the lesion to avoid continued destruction of coronal structure.
The dentigerous cyst is a developmental cyst that encloses the crown of an unerupted tooth
by expansion of its follicle and is attached to its neck.
The possibility should be considered that a cyst in a pseudodentigerous relation, in which the crown of an unerupted tooth
was not inside the cyst, might be clinically and radiologically misinterpreted as a dentigerous cyst.
