The purpose of the present study was to evaluate the interrelationship between the mixed odontogenic tumors. A population of 292 cases--9 cases from our own files, 283 cases taken from the literature--was considered. Data concerning age, sex distribution and site of occurrence of the different lesions were statistically analyzed. The results showed a significant prevalence of odontomas in the anterior region and a highly significant correlation for age and site distribution in relation to the various lesions. It is supposed that ameloblastic fibroma, ameloblastic fibro-odontoma and odontoma represent different maturational stages of the same lesion whose histogenesis is linked to the odontogenic process
