Nonendodontic lesions misdiagnosed as pathoses of endodontic origin are often referenced in the literature. One of the most frequent nonodontogenic cysts of the oral cavity, the nasopalatine duct cyst (NPDC), can be misdiagnosed as endodontic in nature.
A case is presented in which a patent NPDC was originally diagnosed as a sinus tract with subsequent endodontic nonsurgical retreatment and eventual extraction before endodontic consultation.
After surgical treatment, a histopathologic diagnosis of an NPDC was confirmed.
If diagnosed incorrectly, inappropriate endodontic treatment of a NPDC may be initiated to include unnecessary extraction. An increased understanding of anatomy, the use of appropriate diagnostic tests to include cone-beam computed tomography imaging, and key examination techniques to distinguish endodontic lesions from nonendodontic pathoses are imperative for an accurate differential diagnosis and appropriate treatment outcome.
文献中经常提到被误诊为牙髓源性病变的非牙髓性病变。口腔中最常见的非牙源性囊肿之一，即鼻腭管囊肿（NPDC），在本质上可能被误诊为牙髓性病变。
本文介绍了一例病例，该病例中一个开放的NPDC最初被诊断为窦道，随后进行了牙髓非手术再治疗，最终在进行牙髓咨询之前拔除了患牙。
手术治疗后，经组织病理学诊断确诊为NPDC。
如果诊断错误，可能会对NPDC进行不适当的牙髓治疗，包括不必要的拔牙。增强对解剖结构的了解，使用包括锥形束计算机断层扫描成像在内的适当诊断测试，以及用于区分牙髓病变与非牙髓性病变的关键检查技术，对于准确的鉴别诊断和适当的治疗结果至关重要。
