Background: Odontogenic cysts and tumors are lesions that tend to arise from the tooth apparatus or its remnants. Odontogenic cysts and tumors constitute an important aspect of oral maxillofacial pathology as they can be diagnosed in general dental practice. Aim: The purpose of this study was to evaluate the prevalence of odontogenic cysts and tumors diagnosed in the UAE and to compare the results with findings in the literature. Materials and Methods: Data of odontogenic cysts diagnosed between 1990 and 2010 were collected from the files of the Oral Pathology Laboratory and Oral Surgery Department of Tawam Hospital, UAE. Results: Most of the prevalent odontogenic cysts are radicular cysts (69.1%) - followed by dentigerous cysts (7.9%). Among the odontogenic tumors, the most prevalent is odontoma (12.2%) followed by ameloblastoma (2.9%). The middle and posterior mandible was the most common anatomic site for the formation of cysts and tumors. In fact, 93.4% of patients over 40 years presented with odontogenic cysts, whereas 6.3% presented with odontogenic tumor. Odontoma as odontogenic tumor was seen mostly in the first and second decades of life. Conclusion: The prevalence of odontogenic cysts was similar to that reported in the literature, with inflammatory cysts occurring most frequently.
