摘要 目的探讨脉冲Nd:YAG激光联合氢氧化钙在窦道型慢性根尖周炎患牙治疗中的应用。方法选择窦道型慢性根尖周炎患牙280颗,常规去腐质,备洞,拔根髓,扩大根管至35#~40#扩大针。隔湿,干燥,用脉冲激光治疗机的光纤作照射治疗。照射窦道时,将光纤头插入窦道内,达根尖部,反复照射,不可遗漏,然后缓慢退出。上述操作可重复2~3次。照射完成后,髓腔内置氢氧化钙糊剂,丁氧膏暂封。5~7d复诊,若窦道封闭,牙无叩痛,常规完成根管充填。若瘘道窦道未封闭或有叩痛,重复第一次的操作。结果280颗患牙总有效率91%。结论脉冲Nd:YAG激光联合氢氧化钙治疗窦道型慢性根尖周炎不失为一种疗效较好的治疗方法,在临床上有一定的应用价值。
