BORGES, Leandro Bezerra et al. Odontogenic lesions of the jaw: a clinical-pathological study of 461 cases. RGO, Rev. gaúch. odontol. (Online) [online]. 2012, vol.60, n.1, pp. 71-78. ISSN 1981-8637.

Objective To establish the epidemiological profile, according to the variables of sex, age group and location of cysts and odontogenic tumors, in the state of Ceará. Methods A survey was performed of cases of odontogenic lesions diagnosed and recorded between 1994 and 2009 in the Biopsy Service of the Department of Pathology and Forensic Medicine at the Federal University of Ceará. A total of 48 procedures (24.12%) were grafts using particulate bone while sinus lift grafts were performed on 28 patients (14.07%). Osteogenesis distraction and inferior alveolar nerve lateralization were performed in five (2.51%) and three (1.51%) procedures respectively. Eleven autogenous bone grafts were lost, of which 90.9% were onlay block. Results We obtained a total of 461 odontogenic cystic and tumor lesions. Among the cysts, the periapical cyst was the predominant lesion with 196 cases, which predominantly occurs between the age of 21 and 30 years (n=60) and in females (n=120). Ameloblastoma was the most common tumor (n=47) and was most frequently observed between 21 and 30 years of age (n=15) and in females (n=35). Conclusion Case series of epidemiological profile of cysts and tumors, contribute to the understanding of the etiological and clinical aspects of these lesions and they also help to confirm correct diagnosis and appropriate treatment
