摘　　要：目的探讨氢氧化钙剂用于口腔科慢性根尖周炎患者根管内消毒中的应用价值。方法选择2013年6月~2014年6月浙江省慈溪市观海卫镇卫生院收治的慢性根尖周炎患者108例,随机分成研究组与对照组,每组54例。对照组运用樟脑酚棉球根管内消毒,研究组采用氢氧化钙剂根管内消毒,比较分析2组患者的临床治疗效果。结果治疗7 d后,研究组治疗总有效率为98.15%,显著高于对照组的79.63%（χ2=9.375,P〈0.05）。根管治疗结束后随访6个月时研究组的临床总有效率为94.44%,显著高于对照组的77.78%（χ2=6.271,P〈0.05）。研究组中根管疼痛（endodontic interappointment pain,EIP）的发生率为11.11%,显著低于对照组的25.93%（χ2=3.93,P〈0.05）。结论氢氧化钙剂运用于慢性根尖牙周炎口腔科根管内消毒疗效显著,可以明显减少EIP发生率,促进患者根尖牙周炎更快愈合,是基层医院口腔科首选的一种根管内消毒剂。Objective To explore the application value of calcium hydroxide agent in root canal disinfection of patients with chronic periapical periodontitis in stomatology department. Methods 108 cases patients with chronic periapical periodontitis from June 2013 to June 2014 in Cixi Guanhaiwei Zhen Health Centers were randomly divided into study group（ n = 54） and control group（ n = 54）. The control group received camphor phenol cotton for root canal disinfection,and study group received calcium hydroxide agent. The clinical curative effect between two groups was compared. Results After 7 days＇ treatment,the total effective rate was 98. 15% in study group,which was significantly higher than 79. 63% in control group（ χ2= 9. 375,P〈0. 05）. After follow up 6 months,the total effective rate was 94. 44% in study group,which was significantly higher than77. 78% in control group（ χ2= 6. 271,P〈0. 05）. The incidence of endodontic interappointment pain（ EIP） in study group was 11. 11%,which was significantly lower than 25. 93% of control group（ χ2= 3. 93,P〈0. 05）. Conclusion Calcium hydroxide agent has a significant efficacy on in root canal disinfection of patients with chronic periapical periodontitis in stomatology department,could reduce the incidence of EIP and promote healing of chronic periapical periodontitis,which is the first disinfectant in the stomatology department of primary hospital.
