Dentigerous Cyst- A Case Report

Dentigerous cyst is one of the most common odontogenic cyst encountered in the maxillofacial region. They are more frequent in males and although most often affected teeth are maxillary canines and mandibular third molars, they may also be related with supernumerary or an unerupted tooth. Rarely dentigerous cysts present with a grotesque dimension, here we report a rare case of dentigerous cyst associated with an impacted right anterior maxillary canine. A 20 year old male patient was referred to the department of Oral Medicine and Radiology with the complaint of a painful swelling over the right cheek region since the past 3 years. All the permanent teeth were present except the right maxillary canine. External examination showed that the face was gently asymmetrical; levels of eye globes were abnormal. Radiographic examination revealed an expansile unilocular cystic lesion with smooth corticated borders which was located on the roof of the right maxillary sinus. The patient's symptoms were resolved completely after surgery. To avoid unwanted effects of a dentigerous cyst, unerupted tooth should be observed with radiographic imaging. Some untreated dentigerous cysts may become large and have a potential to develop into an odontogenic tumor.
