Abstract

The inflammatory dentigerous cyst (IDC) occurs as a result of spread of an inflammatory exudate from a non-vital, decayed or endodontically treated deciduous tooth to the permanent tooth follicle. Although diagnosis of the lesion is possible with two-dimensional imaging modalities, nevertheless, three-dimensional (3D) imaging such as cone-beam-CT (CBCT) offers an advantage of assessing the 3D anatomical localization and extension of the cyst, which is necessary for formulating an optimal surgical treatment plan. Due to the rarity of evidence related to CBCT based diagnosis of the IDC, the aim of this study is to present a series of three cases of IDC following endodontic treatment of deciduous molars. A clinician should be aware of the IDC occurrence and perform a regular clinical and radiological follow-up following endodontic interventions and if delayed shedding of the deciduous teeth and dentigerous cyst are observed in the same region.

乳牙根管感染后未解决的炎性牙囊肿:3例CBCT成像报告

炎症性牙囊肿(IDC)的发生是由于炎性渗出物从非重要的、腐烂的或经根管治疗的乳牙扩散到恒牙毛囊。虽然可以通过二维成像方式诊断病变，但三维(3D)成像(如锥束ct (CBCT))提供了评估囊肿三维解剖定位和扩展的优势，这对于制定最佳手术治疗计划是必要的。由于基于CBCT诊断乳牙牙髓缺损的相关证据较少，本研究的目的是报道三例乳牙牙髓治疗后发生牙髓缺损的病例。临床医生应注意IDC的发生，并在根管干预后进行定期的临床和影像学随访，以及是否在同一区域观察到乳牙和含牙囊肿的延迟脱落。
