PURPOSE: This retrospective study was intended to assess the frequency and distribution of different types of odontogenic tumors relative to the WHO 2017 latest updates, by reviewing the records of the oral and maxillofacial department, faculty of dentistry in Alexandria throughout
a 5- year period.
METHODS: The records related to the years January 2014 till December 2018 at the oral and maxillofacial department of the faculty of dentistry in Alexandria were inspected. The odontogenic tumors were investigated for the frequency, gender, age, site. The data was recorded then analyzed using Microsoft Excel 2016.
RESULTS: Two hundred and fifteen tumors were documented, out of which 26 (12.09 %) cases confirmed the diagnosis of odontogenic tumors (OTs). 15 (57.69%) of the assessed OTs occurred in females while 11 (42.31%) were seen in males. The average age of the patients was 28.65 ranging between 7 and 73 years. Benign odontogenic tumors comprised 23 (88.46%) cases while 3 (11.54%) cases were malignant. 14 (53.85%) of the assessed OTs were located in mandible the while 12 (46.15%) were in the maxilla. The odontoma was found to be the most prevalent OT represented in 9 (34.62%) cases followed by ameloblastoma in 4 (15.38%) cases.
CONCLUSIONS: Differences between our findings and those of previous studies of various populations were witnessed. OTs may greatly diverge according to the version of classification used and by the sample size of the study.
