目的下颌骨大型囊性病变(直径35 mm)的治疗一直存在争议。很少有研究确定减压后的下牙槽神经功能，而下牙槽神经功能是治疗此类病变的主要选择之一。方法22例下颌骨大型囊性病变患者，诊断为角化囊性牙源性肿瘤、成釉细胞瘤或含牙囊肿。分别于减压前、减压后1、3、6、9、12、24个月对患牙进行牙髓活力监测，观察下牙槽神经功能。减压后牙髓活力恢复，提示下牙槽神经功能恢复。结论下颌大型囊性病变患者减压后下牙槽神经功能明显恢复，主要表现为患牙牙髓活力的恢复。对于根尖暴露在囊性病变中且无牙髓的牙齿，首选减压治疗，而不是根管治疗。
ObjectiveThe treatment of large mandibular cystic lesions (diameter>35mm) is controversial. Few studies determine the inferior alveolar nerve function after decompression which is one of the major options for treating such lesions. We aim to investigate the recovery of inferior alveolar nerve function after decompression.MethodsTwenty-two patients with large mandibular cystic lesions, diagnosed as keratocystic odontogenic tumor, ameloblastoma, or dentigerous cyst, were included. Inferior alveolar nerve function was observed by monitoring the pulp vitality of involved teeth (n=64) with electric pulp test before decompression and 1, 3, 6, 9, 12, and 24months after decompression, respectively.ResultsThe pulp vitality of the involved teeth was significantly decreased before decompression. Recovery of pulp vitality could be observed after decompression, indicating the recovery of inferior alveolar nerve function. A majority (96.9%) of the vital pulp was preserved in the involved teeth after decompression.ConclusionsRecovery of inferior alveolar nerve function was remarkable in patients with large mandibular cystic lesions after decompression, indicated by the recovery of pulp vitality of involved teeth. When decompression is preferred, conservative therapy rather than root canal therapy is recommended for the teeth with root tip exposed in the cystic lesions and without pulposis.
