Gardner syndrome is known as a variant of familial adenomatous polyposis. This syndrome is characterized by multiple intestinal polyposes, osteomas, and epidermoid cysts. In addition, dental abnormalities include an increased frequency of multiple odontomas, as well as supernumerary and impacted teeth. The authors report the case of a 7-year-old male patient with Gardner syndrome. Radiographic findings revealed multiple osteomas in both sides of the maxilla, multiple diffuse enostoses in both jaws, and a complex odontoma in the left mandibular body. Two years later, multiple epidermoid cysts on the scalp were found. Since this patient was suspected to have Gardner syndrome, the authors recommended gastrointestinal endoscopy to check for intestinal polyposis. Gastrointestinal endoscopic examination revealed multiple polyposes in the upper gastrointestinal tract and fundus of the stomach. As a result, the final diagnosis was Gardner syndrome.

A case of calcifying odontogenic cyst associated with an unerupted tooth which appeared in the left maxillary sinus of a 16-year-old woman, was reported. Clinical examination revealed painless swelling on the left maxillary posterior region and the cheek. Radiographically, this lesion showed a monolocular radiolucent shadow with calcified materials and unerupted maxillary second premolar. Histological examination revealed cystic structure with presence of the ghost cells, calcified tissue and unerupted tooth. This lesion was classified as Type IB of COC according to classification of the Praetorius. After surgical removal of the cyst, the wound healed uneventfully and the lesion is now free of symptoms.
