【 摘 要 】

30.41%), followed by odontoma(21.12%). The 947 tumors were found in 501 males and in 446 females(1.12:1). Statistical analysis revealed no difference in the distribution of OTs in relation to gender. The age of patients at diagnosis ranged from 1 to 87 years with a mean of 31.23 years. The exact locations of OTs were known in 912 cases. The most frequently affected area was the molar region of the mandible, with 49.31% of all tumors. With regard to the extent of tumors, 7.04% of all OTs expanded across the midline of the jaws, ramus was involved in 35.01% of all mandibular tumors, and maxillary sinus was affected by 5.98% of all maxillary tumors.4. conclusionThe present study identified some similarities between our data and previous studies from Africa and Asia and some differences compared with the reports from the American and European countries. But it was remarkable that, among Asian and African countries, incidence of ameloblastoma in our series was the most lowest, and that of odontoma was the most highest.Key Words : Odontogenic tumor, Prevalence, Ameloblastoma, Keratocystic odontogenic tumor, Odontoma, WHO classification　 Student Number : 2009 - 22715
