【目的】观察银荷漱口液用于根管消毒的临床疗效。【方法】选择需行根管治疗的47例（48颗患牙），随机分成试验组22例（22颗患牙）和对照组25例（26颗患牙），试验组采用银荷漱口液进行根管消毒，对照组采用樟脑酚（camphor phe-nol， CP）进行根管消毒，封药1周后评价2组的临床效果及安全性。【结果】（1）所有受试对象在试验期间均未发现软组织过敏、烧灼等不良反应，感染根管一次封药后有效者即可行根管充填。（2）封药1周后复诊，试验组有效率为95．45％，对照组有效率为100．00％；2组比较，差异无统计学意义（P＞0．05）。【结论】银荷漱口液具有与樟脑酚相似的根管消毒效果，为临床应用提供了依据。%Objective To evaluate the clinical efficacy of Yinhe gargle on infected root canals. Methods Forty-seven cases of root canal infection ( involving 48 affected teeth) were randomly divided into two groups. The experimental group (22 cases involving 22 affected teeth) was given intracanal medicament with Yinhe gargle, and the control group ( 25 cases involving 26 affected teeth) was given root canal disinfection with camphor phenol. After intracanal medicament for one week, therapeutic effect and safety were evaluated in the two groups. Results ( 1) During root canal disinfection, none of the subjects had adverse reaction such as hypersensitiveness or cauterization of soft tissue. Canal obturation was available after the first intracanal medicament for the infected root canals. (2) After intracanal medicament for one week, the effective rate in the experimental group was 95.45%, and was 100.00%in the control group, the difference being in significant (P>0.05). Conclusion Yinhe gargle has similar disinfection effect to camphor phenol on infected root canals, and it can be used as disinfection medicament for root canals.
