摘要
目的:探讨根尖脓肿软膏治疗窦道型慢性根尖周炎的临床疗效。方法:收治慢性窦道型根尖周炎患者120例,随机分成三组,每组40例(40颗牙)。Ⅰ组根管内用糊剂输送器将根尖脓肿软膏导入根管,直到充满根尖,或从瘘管溢出;Ⅱ组根管内导入氢氧化钙糊剂;Ⅲ组根管内封入FC棉捻,氧化锌丁香油糊剂暂封。结果:Ⅰ组出现约诊间疼痛4例,约诊间疼痛发生率为10.0%,Ⅱ组出现约诊间疼痛8例,诊间疼痛发生率为20.0%,Ⅲ组出现约诊间疼痛13例,约诊间疼痛发生率为32.5%。Ⅰ组约诊间疼痛发生率明显低于Ⅱ组和Ⅲ组,与Ⅱ组、Ⅲ组比较差异有显著性(P<0.05),Ⅰ组总有效率为92.5%,Ⅱ组为85.0%,Ⅲ组为60.0%,Ⅰ组总有效率明显高于Ⅱ组和Ⅲ组,与Ⅱ组和Ⅲ组比较差异有显著性(P<0.05)。结论:根尖脓肿软膏治疗窦道型慢性根尖周炎的疗效显著。
Objective：To investigate the clini- cal efficacy of the treatment of sinus chronic periapical apical abscess ointment. Meth- ods： collected in our hospital from August 2011 to November 2012, the treatment of 120 patients with chronic sinus the periapi- cal patients, were randomly divided into three groups of 40 cases,40 teeth,group 1 root canal paste feeder the apical abscess ointment into the root canal, until full root tip, or overflow from the fistula ; calcium hy- droxide paste group lI root canal import; m group root canal is filled with FC cotton twist, zinc oxide eugenol paste is temporarily closed. Results ： about pain clinics, pain between appointments was 10.0% ,group U about pain clinics, pain clinic, was 20.0% in group m i 3 cases pain appointmentappointment of pain was 32.5%, the pain- between group I about attending the inci- dence was significantly lower than group II and HI group,with group II , III group a sig- nificant difference （ P 〈 O. 05 ） , I group, the total efficiency 92.5% , lI group,the to- tal effective rate of 85.0% , m group, the to- tal effective rate was 60.0%, I group was significantly higher than the group II and BI group, compared with group 1I and m group a significant difference （ P 〈 O. 05 ）. Conclusion ：The the apical abscess ointment treatment sinus chronic periapical significant effect worthy of promotion.
