摘　　要：目的研究液氮冷冻疗法应用于急性牙髓炎治疗的临床疗效。方法选取急性牙髓炎患者300例300颗患牙,随机分成3组,每组各100颗患牙。液氮组用液氮冷冻疗法,麻醉组用麻醉法,失活组用失活法,比较3种方法用于急性牙髓炎应急治疗的镇痛效果、止血情况、术后疼痛缓解效果、术后并发症及患者心理状态。结果液氮组镇痛效果明显优于失活组,差异有统计学意义(χ2=31.25,P<0.01)。液氮组止血效果优于麻醉组,差异有统计学意义(χ2=55.17,P<0.05)。液氮组在术后疼痛缓解方面优于麻醉组和失活组,差异有统计学意义(P<0.05),液氮组在术后并发症方面低于麻醉组和失活组,差异有统计学意义(P<0.05)。在术前、术中、术后的患者心理状态方面液氮组优于麻醉组和失活组,差异有统计学意义(P<0.05)。结论液氮冷冻疗法用于急性牙髓炎治疗是一种操作简单、患者易于接受、无副作用、无创、无痛的新疗法,具有临床应用价值。Objective To observe the effect of liquid nitrogen cryotherapy in the treatment of acute pulpitis. Methods Three hundred patients suffered from acute pulpitis were randomly divided into 3 groups, treated with liquid nitrogen eryotherapy （group A ） , anesthesia （group B） , inactivation （group C） respectively. The analgesic effects and bleeding, postoperative pain mitigation of the effects and complications, preoperative, intraoperative, and postoperative mental state of patients were compared among the three methods in the emergency treatment of acute pulpitis. Results In group A and group B, analgesic effect was obviously better than group C （ P 〈0.01 ）. The hemostatic effect of group A was bet- ter than that of group B （ P 〈 0.01 ）. Group A in postoperative pain relief was superior to group B and C （ P 〈 0.01 ）. Acute apical periodtmtitis incidence of Group A was significantly lower than those of group B and C （P 〈 0.01 ）. There was significant difference （P 〈0.01 ） among the 3 groups in the preoperative, intranperative, and postoperative mental status of the patients. Conclusion The liquid nitrogen clyotherapy in the treatment of acute pulpitis is a simple opera- tion, and easy for patients to accept, without side effect and painless. It is worth promoting in clinical practice.
