Central giant cell granuloma is a benign intraosseous lesion of the jaws occurring mostly in persons under the age of 30. Females comprise 65 % of all the cases. Mandible is affected 2 to 3 times more often than maxilla. The aetiology of this disease remains unclear, but the occurrence of central giant cell granuloma has been repeatedly described in connection with a primary tooth injury. That was also the case of our patient. At the age of three, he suffered an injury of the tooth No. 51, but he visited our dental office four years later at the age of seven due to an impacted tooth No. 11, which was dislocated high into the vestibule. The dislocation was caused by a demarcated radiolucent lesion that was removed by simple curettage. The adjacent permanent teeth follicles were left in situ. The histological examination confirmed the clinical diagnosis of a central giant cell granuloma. Within 19 months, the defect healed with the osseous tissue, development of all adjacent permanent teeth was not impaired and orthodontic treatment commenced that continues successfully to date. The relationship between central giant cell granuloma and other giant cell processes of the jaws especially bone cysts is still being discussed. Recent genetic foundings have brought new light into this. The lesion has two variants – non-aggressive and aggressive that clinically differ from each other. The clinical manifestations range from asymptomatic processes and dislocations of adjacent teeth to rapid growth, pain, destruction of bone corticalis and resorption of adjacent teeth. Therapeutical possibilities include both classical surgery and medicamentous therapy with intralesional administration of corticoids or systemic therapy with calcitonin.
