囊肿和牙源性肿瘤的流行病学对于鉴别诊断和治疗策略很重要。我们的目的是使用当前的 WHO 分类来描述智利人群中囊肿和牙源性肿瘤的流行病学特征。我们回顾了 1984 年 1 月至 2023 年 9 月期间智利圣地亚哥市长大学牙科学院口腔病理科收到的 22,914 份活检请求。选择诊断为颌骨囊肿和牙源性肿瘤的患者，并记录有关年龄、性别和位置的信息。4226 例（18.4%）为囊肿，551 例（2.4%）为牙源性肿瘤，年龄范围为 2 岁至 97 岁。男性占样本总数的54.4%，女性占45.7%。最常见的囊肿是根性囊肿（58.6%）、含牙囊肿（17.9%）和牙源性角化囊肿（13.3%）。最常见的牙源性肿瘤是牙源性肿瘤（40.1%）和传统成釉细胞瘤（17.6%）。我们的研究是第一个根据 2022 年 WHO 分类确定囊肿和牙源性肿瘤的流行病学特征的回顾性分析。这是相关的，因为它为全面比较这些实体的流行病学特征提供了潜在的基础，这可能有助于准确的鉴别诊断，从而导致更有效的治疗干预措施。© 2024 John Wiley

The epidemiology of cysts and odontogenic tumors is important for differential diagnosis and treatment strategies. We aimed to describe the epidemiological features of cysts and odontogenic tumors in the Chilean population using the current WHO classification.We reviewed 22,914 biopsy requests received between January 1984 and September 2023 at the oral pathology department, School of Dentistry, Universidad Mayor, Santiago, Chile. Patients diagnosed with cysts of the jaws and odontogenic tumors were selected and information regarding age, sex, and location was recorded.4226 (18.4%) were cysts, and 551 (2.4%) were odontogenic tumors, ranging from 2 to 97 years old. Males represented 54.4% and females 45.7% of the total sample. The most prevalent cysts were radicular cysts (58.6%), dentigerous cysts (17.9%), and odontogenic keratocysts (13.3%). The most prevalent odontogenic tumors were odontomas (40.1%) and conventional ameloblastoma (17.6%).Our study was the first retrospective analysis to determine the epidemiological features of both cysts and odontogenic tumors together, based on the 2022 WHO classification. This is relevant as it offers a potential basis for comprehensive comparisons of the epidemiological features of these entities, which could contribute to an accurate differential diagnosis, therefore, leading to more effective therapeutic interventions.© 2024 John Wiley & Sons Ltd.
