Abstract

Objective: To determine the frequency and types of cysts and tumors around the impacted mandibular third molars (IMTMs) in the Thai population.

Methods: This study was a retrospective study of the histopathologic results of the lesions associated with IMTMs from January 2022 to December 2023. In addition, the age and sex of the patients, panoramic radiographs were also reviewed. The IMTMs with other impacted teeth and patient who had incomplete data record or poor quality panoramic films were excluded.

Results: In a period of two years, the 2,355 IMTMs were removed. Among these, the incidence of cysts and tumors around IMTMs was 1.86% (44 lesions of 42 patients). The mean age was 36.07 years with male predominance. Most cases (72.73%) demonstrated unilocular radiolucency in the radiographs. The incidence of cysts around IMTMs was 1.57% with dentigerous cysts in majority. Bilateral dentigerous cysts associated with IMTMs were found in 2 patients with no underlying syndromes or systemic diseases. While the incidence of benign tumors around IMTMs was 0.29% with ameloblastoma in majority, malignancy was not found.

Conclusion: Although the results indicated that cysts and tumors can develop in relatively small chances in a minority of patients, it was a crucial pathologic condition that cannot be underestimated due to complications after surgery. The decision to remove IMTMs requires careful thought and evaluation for individual patients.

泰国人群中与下颌第三磨牙阻生有关的囊肿和肿瘤的发生率。

目的：了解泰国人群下颌阻生第三磨牙（IMTMs）周围囊肿和肿瘤的发生频率和类型。方法：本研究回顾性分析2022年1月至2023年12月imtm相关病变的组织病理学结果。此外，还对患者的年龄、性别、全景x线片进行了回顾。排除有其他阻生牙的IMTMs及资料记录不完整或全景片质量差的患者。结果：在两年的时间里，共切除了2355个imtm。其中imtm周围囊肿及肿瘤发生率为1.86%（42例44个病变）。平均年龄36.07岁，男性居多。大多数病例（72.73%）在x线片上显示单眼透光。imtm周围囊肿发生率为1.57%，以含牙性囊肿居多。2例患者无基础综合征或全身性疾病，伴有双侧牙性囊肿。imtm周围良性肿瘤发生率为0.29%，以成釉细胞瘤居多，未见恶性肿瘤。结论：虽然在少数患者中出现囊肿和肿瘤的几率相对较小，但由于术后并发症，囊肿和肿瘤是一个不可低估的关键病理状态。移除imtm的决定需要对个别患者进行仔细的考虑和评估。
