Abstract

Aim: The aim of the current study is to determine the frequency of DCs and OKCs in biopsies submitted to the oral pathology department of the Faculty of Dentistry, Ain Shams University and to compare our findings with data from similar studies conducted globally.
Material and methods: This retrospective study was conducted in the Oral Pathology Department at Ain Shams University, analyzing patient records from January 2013 to December 2022. The data were organized in an Excel spreadsheet for analysis.
Results: A 10-year analysis of submitted 1476 biopsies found 77 cases of DCs and 39 of OKCs. Among DC cases, 67.63% were male, with the 20-29 age group being most affected (33.8%), and 66.23% located in the mandible. OKCs showed 56.41% male prevalence, most common in ages 20-39 (50%). The maxilla was more frequently affected by 51.28%. Radiographically, 75% were unilocular, with 57.14% not associated with teeth.
Conclusion: DCs were more common in males, peaking in the third decade, often in the mandible. Radiographically, they appeared as well-defined unilocular radiolucencies linked to impacted teeth. Similarly, OKCs showed well-defined unilocular radiolucencies, also prevalent in males, typically in the third and fourth decades, but with higher incidence in the maxilla than the mandible.
