ABSTRACT Background Updated and comprehensive epidemiological data on odontogenic tumors are not available for the Nordic countries. The aim of study was to retrospectively examine prevalence clinical radiological characteristics primary over a 10‐year period in Sweden, Norway, Finland, Denmark. Methods Primary diagnosed by oral pathologists from 2010 2020 at nine different diagnostic laboratories Denmark were identified. Using histopathology referrals their corresponding histopathological reports, age sex, anatomic site, findings, tentative diagnosis, recurrence recorded. Range, mean, median continuous variables frequency tabulation discrete used. Results In total, 1139 (598 males 540 females) identified during period, giving an annual incidence rate 4.2/million. mean all patients 29 years. Ninety‐nine percent benign, mandible predominant location. Odontoma, ameloblastoma, fibroma three most common tumors. mixed epithelial mesenchymal benign more younger compared with (mean 22, 44, 35 years, respectively). Information other than age, tumor site missing referrals. Conclusion 4.2 cases per million indicates that uncommon Better practices improve quantity quality information pathology needed.
