Abstract：
BACKGROUND: To investigate the radiological and demographic features, types, distribution, and treatment methods of dentigerous cysts (DC).
METHODS: Panoramic radiographs and cone beam computed tomography (CBCT) images of patients diagnosed with DC based on biopsy results between January 2020 and December 2023 were examined. In patients from different age groups, the numbers, types and locations, and radiological features of DCs, associated changes in surrounding tissues, and treatment methods used were reviewed.
RESULTS: Among 95 patients with DC (66 males, 29 females), sex and age distributions were comparable between those with a single cyst (n = 86) and those with two cysts (n = 9). Of 104 DCs, 44 were central, 38 were lateral, and 22 were circumferential. DC types were not significantly affected by sex, age group, or anatomical location. Circumferential DCs often caused displacement of the mandibular canal inferiorly. While enucleation was preferred for the treatment of central DCs, circumferential DCs were treated with marsupialization.
CONCLUSIONS: In this study, which is the first to evaluate the DC types on CBCT images, the central type was the most common. Circumferential DCs were mostly treated with marsupialization. CBCT imaging can assist in determining DC types, and may provide guidance for treatment planning.

摘要：
背景：为了调查放射学和人口统计学特征，类型,分布，和治疗方法的牙科囊肿（DC）。
方法：检查了根据2020年1月至2023年12月的活检结果诊断为DC的患者的全景X线照片和锥形束计算机断层扫描（CBCT）图像。在不同年龄段的患者中，数字，类型和位置，和DC的放射学特征，周围组织的相关变化，并对所采用的治疗方法进行综述。
结果：在95例DC患者中（66例男性，29名女性），单个囊肿（n=86）和两个囊肿（n=9）的性别和年龄分布相当。在104个DC中，44是中央的，38是横向的，和22个是圆周的。DC类型受性别影响不显著，年龄组,或解剖位置。周向DC通常导致下颌管移位。虽然摘除是治疗中枢DC的首选方法，周围的DCs进行有袋化处理。
结论：在这项研究中，这是第一个评估CBCT图像上的DC类型，中心型是最常见的。环状DCs大多采用有袋化处理。CBCT成像可以帮助确定DC类型，并可能为治疗计划提供指导。
