Introduction: Peripheral odontogenic tumors are rare and there is no valid information of the frequency of them in the literature. This study aims to obtain the frequency of these tumors.
Materials and Methods: The files of oral and maxillofacial pathology (microscopic reports and slides), faculty of dentistry, Shahid Beheshti University of medical sciences served as the source of the material during a 20-year-period for this retrospective,descriptive cross-sectional study. Clinical information including, patient’s age, gender and location was record-ed.
Results: Three hundred seventy nine cases of odontogenic tumors were assessed in which 16 cases (4.22%) were peripheral and 363 cases (95.77%) central. Peripheral odontogenic fibroma was the most common case of the 16 peripherals accounting for 10 cases (62.5%) followed by peripheral ameloblastoma(25%) and peripheral dentinogenic ghost cell tumor (12.5%). The peripheral type of odontogenic fibroma was more common than central counterpart (3.3:1).
 Conclusion: In our study, similar to the previous ones, the relative frequency of the peripheral odontogenic tumors was low and peripheral odontogenic fibroma was the most common tumor among other peripheral subtypes. Unlike other types, the incidence of peripheral odontogenic fibroma was higher than the central odontogenic fibroma.
