This study contained the clinicostatistical analysis of the frequency in relation to sex, age, location, chief complaints, duration, radiographic findings, recurrence, impacted teeth and treatment methos. The results were as follows: 1. Ameloblastoma showed the highest incidence of 67 cases (91.3%) in 73 odontogenic ectodermal tumors. 2. There was a wide age distribution, ranging from 9 to 69 years. (average: 31 years) 3. The distribution of male was slight greater than that of female, 43 cases (589%) male and 30 cases (41.1%) female. (ratio 1.4:1). 4. The majority of cases occurred in the andible (59 cases 80.8%). Only 14 cases (19.2%) occurred in the maxilla. 5. Chief complaints of swelling without any complants showed 57.5% and swelling with pain presented 21.9%. 6. As regards duration, the cases of less than 1 year presented 43.8% in highest incidence. 7. It is that polylocular type showed 60.3% and monolocular type presented 39.7%, in radiographic findings. 8. Recurrence rate presented 32.9%. 9. There aie variations of lesional sizes between 2.0㎝ and 11.2㎝. (average: 5.64㎝) 10. 30% of odontogenic ectodermal tumors had impacted teeth. 11. Conservative treatment was performed 31.5% and radical treatment was performed 68.5%. 12. In ameloblastoma, radical treatment was performed more frequently in case of old age group (p < 0.05), polylocular group (p < 0.01) and long duration group (p < 0.05).
