Overview
The incidence of ameloblastoma is approximately 1.96, 1.20, 0.18, and 0.44 per 100,000 for black males, black females, white males, and white females respectively, worldwide. Ameloblastoma affects men and women equally. There is no racial predilection to the ameloblastoma. Ameloblastoma usually occur in middle age group i.e. 20-40 years; the median age at diagnosis is 39 years.
Epidemiology and Demographics
Incidence
- The incidence of ameloblastoma is approximately 0.5 new cases in 1,000,000 people, worldwide.[1]
Gender
- Ameloblastoma affects men and women almost equally. Although, women tend to be 4 years younger than men when tumors first occur and tumors appear to be larger in females.[2]
- The male to female ratio is approximately 1.2:1.[3]
Race
- There is no racial predilection to the ameloblastoma. However, there is conflicting evidence on the incidence rates in different races.
- Although some reports claim an increased incidence of ameloblastoma in black individuals, a large study identifies Asians as the population with greatest number of affected patients.
- Ameloblastoma is by far the most common unequivocal odontogenic neoplasm in all ethnic groups, representing approximately 1% of head and neck neoplasms in Europe and the USA, some studies claim that it has the highest incidence in Afro-Caribbean populations.[4]
Age
- Ameloblastoma commonly affects adults than younger people, the median age at diagnosis is 39 years.
- They are slow growing and tend to present in the 3rd to 5th decades of life.
- Maxillary and extraosseous ameloblastoma commonly affects individuals in a slightly older age group while unicystic and granular cell ameloblastoma occur in a younger age group.
- The average age of unicystic ameloblastoma is 10.8 years.
Region
- The majority of ameloblastoma cases are reported in Africa, China, and India.[5][6]
