Odontoma composed of dental hard tissues, is a typical odontogenic tumor, which is divided into two types. Generally, the odontomaenlarges up to wal nut size, therefore finding a tumor of this type large enough to require dissection of the jaw is rare.<BR>On the other hand, simple bone cysts termed haemorrhage bone cysts or traumatic bone cysts, occur most often in the humerous and other long bones. They are not often in the jaws.<BR>This paper reports a case where the odontoma and simple bone cyst occurred simultaneously in the same region of the mandible. The patient, a 16-year-old boy, complained of malocclusion on 7 of his gingiva and was refered to this hospital. Roentogenographic examinations revealed the radiopaque region which seemed to contain odontoma in the mandibular body and also showed mutiocular cyst-like radiolucent area in almost all of the ramus which was suspected to be an ameloblastoma.<BR>Mandibular dissection was done from 6 and reconstruction of the jaw was performed using the intact cortex including the condyle after the tumor as enucleated. The histopathological diagnosis was compound odontoma and simple bone cyst.<BR>The patient was observed periodically and the prognosis was good for eight months after the operation.
