摘要
目的观察和分析活髓牙一次法根管充填治疗的近期临床效果。方法2004年6月至2006年12月,以因口腔修复需要、意外穿髓或牙髓炎发作而需行根管治疗的112例患者(230颗活髓牙)作为研究对象。患牙随机分为分次法根管治疗组(对照组,n=102)和一次性根管治疗组(实验组,n=128)。其中实验组在根管预备、干燥后,即使用注射型Vitapex糊剂充满根管,同时采用侧方加压法紧密充填牙胶尖,摄片确定根管适填后,行锌水门汀垫底永久性充填。分别观察、比较两组患者治疗后疼痛改善情况;X摄片复查治疗牙的牙根及周围组织情况。以疼痛程度作为评价临床疗效的标准。结果治疗后1周内患牙疼痛反应为Ⅰ～Ⅲ级的,对照组为100例,实验组为124例,两组比较无显著差异(P>0.05);两组中各有2例患牙的疼痛程度为Ⅳ级(P>0.05)。治疗后3～6月随访结果显示,被访患者均无主诉患牙不适和疼痛感,进食和咀嚼功能正常;牙片复查根周组织未见异常。结论针对活髓牙,一次法与分次法根管治疗可以获得基本相同的临床治疗效果。
Objective To observe and analyse the short-term clinical effect of one-visit root canal therapy（RCT） for vital teeth. Methods From June 2004 to December 2006, 112 patients （230 vital teeth） who were performed root canal therapy for oral restoration, accidental perforation of pulp chamber and endodontitis were selected. The involved teeth were randomly divided into one-visit RCT group （experiment group, n = 128） and multi-visit RCT group （ control group, n = 102）. After preparation and drying of the root canal, Vitapex paste was injected to fill the root canal, and gutta percha point was densely filled by lateral compaction technique. When the root canal was comfirmed properly filled by imaging examination, the permanent obturation was perfomed with Zn-containing hydroxyapatite cement. The pain relief after the treatment was observed and compared between the groups, and the condition of dental roots and adjacent tissues were evaluated by X-ray examination. The degree of pain was adopted as the criterion for therapeutic effect, Results There were 100 teeth in the control group and 124 teeth in the experiment group whose pain reaction was between grade Ⅰ and grade Ⅲ one week after treatment, and no significant difference was found between the two groups（P 〉 0.05）. Two teeth in each group reached degree Ⅳ in pain （ P 〉 0.05 ）. It was revealed that all the patients followed up 3 to 6 months after treatment were free from complaints of the involved teeth, with nomal food intake and mastication. No abnormal adjacent tissues of dental roots were detected by imaging examination. Conclusion For the vital teeth, the similar clinical effect may be obtained by one-visit RCT and multi-visit RCT.
