We investigated the occurrence of inflammatory paradental cysts (IPC) in the mandibular premolar, and demonstrated the points of difference with regard to diagnostic features between IPC and dentigerous cysts (DC).
We analyzed the radiographs and histology of 60 cases with a cystic lesion associated with inflammation in the mandibular premolar region based on diagnostic criteria as IPC.
In 4 out of 60 cases, we diagnosed the 4 cysts as IPCs in the mandibular premolar region, and recognized that one form of IPC was similar to a mandibular infected buccal cyst. The other 56 non-IPC cases were diagnosed as DC. On the IPCs, the permanent tooth normally erupted in all 4 cases after treatment, but in one case, the IPC recurred.
The present investigation suggested that we might have misdiagnosed IPCs in the mandibular premolar region as DC to date. It is important to consider the differences between IPC and DC with regard to the causes of recurrence during treatment of IPC.
我们研究了下颌前磨牙区炎性牙周囊肿（IPC）的发生情况，并阐述了IPC与含牙囊肿（DC）在诊断特征上的差异点。
我们根据IPC的诊断标准，分析了60例下颌前磨牙区伴有炎症的囊性病变的X线片和组织学情况。
60例病例中，有4例被诊断为下颌前磨牙区的IPC，且认识到一种形式的IPC类似于下颌感染性颊囊肿。另外56例非IPC病例被诊断为DC。对于IPC病例，4例在治疗后恒牙均正常萌出，但有1例IPC复发。
目前的研究表明，迄今为止我们可能将下颌前磨牙区的IPC误诊为DC。在IPC治疗过程中，考虑IPC和DC在复发原因方面的差异很重要。
