Abstract
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 cryotherapy (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 better 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 periodontitis 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,intraoperative,and postoperative mental status of the patients.Conclusion The liquid nitrogen cryotherapy in the treatment of acute pulpitis is a simple operation,and easy for patients to accept,without side effect and painless.It is worth promoting in clinical practice.关键词
