Interestingly, approximately 50% of ameloblastomas arise from the lining of a dentigerous cyst
Nasal septal abscess: An unusual presentation of dentigerous cyst
In this article, 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.
are most frequently found in the mandible, but they can also originate in a maxillary canine or molar.

Routine intraoral periapical radiographs are not necessary in all patients, but they do help differentiate other dentigerous cysts
The transformation of a dentigerous cyst

Hundreds of radiographs and color photographs illustrate the placement and activation of appliances, palatally impacted canines, abnormal premolar orientation, infraocclusion, dentigerous cysts
, traumatic impaction, cleidocranial dysplasia.
6] Patients may present with lesions in the wall of periapical cysts with prolonged therapeutic opened drainage or dentigerous cysts
The pathogenesis of these tumors is controversial, but several authors have proposed that they involve a metaplastic transformation of the mucus-secreting cells commonly found in the epithelial linings of dentigerous cysts
and odontogenic epithelium.
