The authors experienced four cases of simple bone cyst occurring in mandibles, and presents them with review of literature.<BR>Case 1: the patient was referred to our department from a dental practioner because of swelling on the right cheek. Cases 2-4: these patients were recommended for further examination of incidental radiolucencies on orthopantomgraphies during conventional dental treatment by dental practioners. Clinical, roentgenographic and operation findings revealed that all teeth associated with the cysts were vital ones without any inclination, absorption or cyst wall. They, therefore, were recognized as simple bone cysts of the mandibles. All of these cases had favorable postoperative courses with new bone formation which were dis-closed on roentgenograms at 18 months after operation in Case 1, 14 months after in Case 2, 9 months in Case 3, and 4 years in Case 4 respectively.<BR>It is difficult to make diagnosis of simple bone cyst, but it seemed that interview on any episode of trauma to applicated region, X-ray examination and electric pulp test of the involved teeth were useful for differentiation from other cystic lesions.
