This report describes a clinical case of asymptomatic compound odontoma in the anterior left side of the maxilla associated with an impacted canine and supernumerary tooth with a gubernacular canal of a 47- year-old female with no relevant medical history. Cone-beam computed tomography (CBCT) was performed for precise three-dimensional localization of each structure and assessment of their spatial relationship with the associated structures before surgery. The treatment protocol involved surgical enucleation of the odontoma and open extraction of both impacted and supernumerary teeth. The patient had uneventful healing and proceeded with the prosthodontic treatment plan. The dentist should be aware of the probability of a close relationship between the development of odontoma and presence of the gubernacular tract, which could be used as a future radiographic diagnostic criterion of an odontoma. Also, we recommend that more studies be performed in this field to deeply analyze the imaging characteristics of GT and its spatial association with various pathological lesions in the future.
本报告描述了一例 47 岁女性患者的临床病例，其上颌骨左侧前部存在无症状的复合性牙瘤，伴有埋伏犬牙和额外牙，并有系带管。该患者无相关病史。锥形束 CT（CBCT）用于在手术前精确地对每个结构进行三维定位，并评估它们与相关结构的空间关系。治疗方案包括牙瘤的外科切除术和埋伏牙及额外牙的开窗拔出术。患者愈合顺利，并进行了修复治疗计划。牙医应该意识到牙瘤的发生和系带管的存在之间存在密切关系的可能性，这可以作为牙瘤的未来影像学诊断标准。此外，我们建议在该领域进行更多的研究，以深入分析 GT 的影像学特征及其与未来各种病理病变的空间关联。
