Ameloblastoma is a benign neoplasm essentially composed of epithelial tissue that has an invasive and infiltrative behavior at local level with a high recurrence rate. The prevalence of tumors and oral cysts is 1%, and the prevalence of odontogenic tumors is about 11%. The etiology is not yet fully known; however, one of the most accepted theories is that the lesion starts developing from remaining cells of the dental lamina, reduced enamel epithelium, Malassez's epithelial rests, or even from a basal cell layer of the epithelium surface. The literature does not report sex-and ethnicity-related occurrence; however, it is known that the most affected anatomical region is the mandible. It is essential to study oral lesions with the purpose of promoting early diagnosis and the most conservative intervention possible. This way, this study is a literature review of works published between 2006 and 2014 conducted to find the existing protocols for the treatment of ameloblastomas.

Aim: The present study aimed to evaluate the prevalence of superficial lesions in the oral cavity mucosa in diabetic patients. Methods: The sample was made of 30 patients. To obtain these results we did rigorous clinical and complementary tests. Results: Of the 30 patients, 9 (30%) were males and 21 (70%) females. Of the studied patients, 40% were below 60 years of age, and 60% were older than 60 years. Thirteen different types of mucosal alterations were diagnosed. Tongue varicose veins (36.6%) and candidiasis (27.02%) were the most prevalent. Such alterations can be associated with the fact that these conditions are commonly found in senile patients and are also associated with prolonged wear of dentures. Xerostomia was diagnosed in only 1 (3.33%) patient, disagreeing with most of the studies observed in the literature. Conclusion: Most of the diabetic patients presented at least one type of oral mucosa lesion or alteration.
