title: A central giant cell granuloma in a patient seeking orthodontic treatment.
abstract: BACKGROUND
  This case report illustrates the need to consider central giant cell granuloma, or CGCG, in the differential diagnosis in cases of greatly displaced teeth and facial deformity. The authors review the literature regarding CGCG and emphasize the importance of early diagnosis and treatment.
  
  
  METHODS
  A 9-year-old boy was seen in an orthodontic office with the chief complaint of overlapping front teeth. On radiographic examination, the authors noted a large maxillary midline radiolucency. The child was referred to an oral and maxillofacial surgeon for definitive diagnosis and treatment.
  
  
  CONCLUSIONS
  Patients may come to dental offices for treatment of malaligned teeth. The dentist needs to be aware of possible oral pathology when malaligned teeth are present. CGCG should be included in the differential diagnosis for patients with greatly displaced teeth and facial deformity.
