Abstract

Abstract: Objective: To investigate the clinicopathologic features of odontogenic tumors (OTs) in southwest China and compare the epidemiologic characteristics of OTs with other areas in order to provide assistance in clinical diagnosis and related research of OTs. Methods: 494 patients with OTs from January 2005 to April 2019 were retrospectively analyzed and the differences in epidemiological status were compared with other areas. Results: Among 494 OTs patients in southwest China, 271 (54.9%) were males and 223 (45.1%) were females. The male-to-female ratio was 1.22∶1. The average age of OTs was (32.99±15.96) years. 484 cases (98%) of OTs were benign, and 10 cases (2%) were malignant. Among all OTs, ameloblastoma (AME) was the most common, accounting for 403 cases (81.6%), followed by 34 cases (6.9%) of Odontomas. The mandible-to-maxilla ratio of OTs was 5.1∶1, and 413 cases (83.6%) occurred in the mandible. Conclusion: The most common OTs in southwest China is AME, especially in young males' mandibles. The incidence of OTs and AME in southwest China is about 0.98 and 0.80 per million person-years, respectively.
