Dentigerous cyst associated with a maxillary permanent lateral incisor: Case report and literature review

Trauma to deciduous teeth can have severe consequences. Dentigerous cysts are common developmental odontogenic cysts of the jaws. They are associated with the crown of an unerupted/impacted or developing tooth. Reported cases most commonly involve mandibular third molars and maxillary canines. They rarely involve the incisors. The condition occurs predominantly in the second and third decades of life. We report a case of dentigerous cyst involving the permanent maxillary lateral incisor, which developed as a consequence to trauma to the deciduous predecessor. The pathogenesis and clinical and radiologic features are discussed
