Management techniques of ameloblastoma: a literature review
ABSTRACT 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...

Potential contribution of periapical radiographic film image processing for forensic identification
This study aimed to report the potential contribution of image processing from radiographic films by digitally edited periapical radiographs for case reporting of positive identification. The results of anthropological examinations and dental arches of the victim matched the information transferred by the family of the missing person. The antemortem and postmortem periapical radiographs were digitized on photo scanner (Hewlett-Packard Development Company, HP ScanJet G4050 Photo, United States) and images were processed in Corel PaintShop Pro X4 editing software (Corel Corporation, v14, Canada). The comparison of antemortem...
