Erupted odontoma has also been reported in association with
dentigerous cyst.[10]
This type of extra teeth might cause several complications, including the prevention of permanent teeth eruption, diastemas,
dentigerous cysts, rotations, crowding, and root resorption problems (14, 15).
Dentigerous cyst (DC), also known as follicular cyst, is the second most common form of odontogenic cysts after radicular cyst (1).
Key Words: Impacted third molars, unerupted teeth, pathologies,
dentigerous cyst, odontogenic keratocyst.
Dentigerous cysts are cysts that develop when a permanent tooth does not erupt through the gum.
The majority of ameloblastomas derive from the odontogenic apparatus (ie, epithelium, enamel organ and its derivatives or remnants), or less commonly from the lining of a
dentigerous cyst.
The radiologist gave a provisional diagnosis as
dentigerous cyst since the mass was attached to the coronal head of the impacted tooth.
Furthermore, SJS was identified as a predisposing factor for development of
dentigerous cysts; advocating its surgical removal to avoid future complications.10
A
dentigerous cyst is a development cyst that surrounds and envelops the crown of an unerupted tooth, attached at the crown-root (cemento-enamel or cervical) junction.
In view of the clinical and radiographic characteristics, two differential diagnoses were raised, namely, unicystic ameloblastoma or
dentigerous cyst (Figure 3).
Most PIOSCCs originate from the epithelial lining of odontogenic cysts, especially radicular, residual, and
dentigerous cysts [1].
