Multi-teeth compound odontoma is rarely tumor. Odontoma is odontogenic original tumor, in which phenomena of induction of dental tissue leads to the formation of enamel and dentine. Odotoma subdivided into Odontoameloblastoma, complex odntoma and compound odontoma. Compound odontoma differs from complex odontoma by its arrangement of dental tissue in order, like normal teeth: enamel, dentine, cementum, connective tissue... although the morphology of teeth is deformed, rudimentary and tiny. In medical literature, there are some cases with several tens or up to 2000 tiny denticles in a tumour. In Vietnam, in 1986 author published a compound odontoma with 16 teeth. This case is a second one with 64 teeth in a compound odotoma of a 15 years old girl with features of odotoma: clinic, X-ray and histology.

All cases of odontoma treated at Hanoi Institute of Odonto-maxillo facial Institute from 1994 to 2004 were investigated. Odontoma had been occurred at any age group, the lowest was 6, the highest was 67 and mean age 20.59 years. 58.82% of Odontoma had been occurred in the upper maxial bone, 41.18% in the lower. Common clinical sumptoms were bone swell in 88.24% of cases, permanent loss of tooth 47.06%, existing milk tooth in 76.47%, pain in 11.76%. In 47.06% the pre-operative diagnosis was agreed with patho-anatomical diagnosis and 93.33% of preoperative diagnosis with pathoanatomical diagnosis Odontoma complex accounted for 73.33% and odontoma compound 26.67%.

Ameloblastic Fibro-Odontoma is a benign tumor defined entity in which both ameloblastic fibroma and complex odontoma combined in one lesion. Tumor occurred 5 years ago in a 10 years old child but destroyed completely the mandible up to condyles. Radiographically, tumor exhibits a large multiocular radiolucent/ radiopaque lesions. Treatment consists of complete resection of the mandible followed by titanium plates reconstruction. Post.op evaluation is normal. Surgical resection and reconstruction is successful

Complex odontoma is a relatively rare dental dysplasia. In particular, a complex odontoma with dentigerous cyst is seldom observed. A case of complex odontoma with dentigerous cyst is reported in this paper.

The purpose of this study was to obtain information on the clinical and radiographic features of the odontomas in the jaws. For this study, the authors examined and analyzed the clinical records and radiographs of 119 patients who had lesion of odontoma diagnosed by clinical and radiographic examinations. The obtained results were as follows ; 1. Odontoma occurred the most frequently in the 2nd decade(45.4%) and occurred more frequently in males(60.5%) than in females(39.5%). 2. The most common clinical symptom was the delayed eruption of the teeth(34.2%). 3. The type of lesions was mainly observed as compound odontoma(80.8%), and internal pattern of the complex odontoma was unevenly radiopaque(73.9%). 4. The compound odontoma frequently occurred in anterior portion of the maxilla(57.7%) and mandible(30.9%), and complex odontoma frequently occurred in anterior portion of maxilla(34.8%) and posterior portion of mandible(30.5%). 5. The effects on adjacent teeth were impaction of teeth(71.7%) and prolonged retention of deciduous teeth(31.7%). 6. The impaction of the teeth occurred in anterior portion of maxilla(44.2%) amd mandible(19.2%), but root resorption of the adjacent teeth were not seen. 7. The boundary to adjacent structure was well-defined, the lesions appear as radiopaque mass with radiolucent rim.
