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).
A number of cases suggest surgical exposure of the unerupted tooth
to restore the lesion to avoid continued destruction of coronal structure.
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.
Jerusalem, Israel) describes techniques for diagnosing impacted teeth, helping an unerupted tooth
to surface, and surgically exposing or removing the problem tooth.
Lara had what is believed to have been an abscess under an unerupted tooth
Rarely, a dental cyst or unerupted tooth
can be the source of the infection.
6) Some 52% of maxillary CEOTs are associated with an unerupted tooth
or buried tooth.
Coronal resorption is manifested histologically by degeneration of the enamel and dentine of the coronal portion of the tooth, which is ultimately replaced by vascular connective tissue it occurs because of a defect in the enamel organ of an unerupted tooth
[Stafne and Austin, 1945; Blackwood, 1958; Owens et al.
1) A dentigerous cyst occurs in conjunction with the crown of an unerupted tooth
However, cases in which the bud of the unerupted tooth
is inferior may fail due to the migration of the unerupted tooth
under the extension.
We report a case of dentigerous cyst of the maxilla and maxillary sinus that caused the ectopic displacement of an unerupted tooth
into the orbital rim and floor.
An area of high attenuation in the posterosuperior wall of the left maxillary sinus was consistent with a displaced, unerupted tooth
