摘要
目的:观察Vitapex糊剂一次性根管充填的术后疼痛反应及疗效。方法:于2004-04/2005-04选择四川省人民医院口腔科慢性根尖周炎患者254例254颗牙,均经医院伦理委员会批准,且患者知情同意。按随机数字表法分为3组:Vitapex糊剂+牙胶尖组85颗牙,Vitapex糊剂组85颗牙,常规根管充填材料+牙胶尖组84颗牙。Vitapex糊剂+牙胶尖组:采用注射型Vitapex糊剂注入根管,再插入牙胶尖。Vitapex糊剂组:充填时仅使用Vitapex糊剂,不插入牙胶尖。常规根管充填材料+牙胶尖组:根管充填时使用常规根管充填材料和牙胶尖。实验评估:①术后疼痛反应评价标准:将疼痛分为无痛、轻度疼痛(稍有疼痛但不影响日常生活),中度疼痛(疼痛明显影响日常生活,但可接受),重度疼痛(疼痛剧烈无法耐受需急诊处理),术后1,3,7d复诊时进行评估。②术后1年疗效评价标准:治疗成功标准:无症状和体征、咬合功能正常、X射线片示根管充填严密合适、尖周透射区消失,牙周膜间隙正常或无症状和体征,咬合功能良好,X射线片示根尖周透射区缩小,密度增加。结果:①术后疼痛反应:Vitapex糊剂+牙胶尖组、Vitapex糊剂组术后1,3d疼痛发生率低于常规根管充填材料+牙胶尖组(分别为10.59%,12.94%,28.57%;8.24%,7.06%,21.43%),差异有显著性意义(x2=8.69,6.29,5.86,7.16,P<0.05),Vitapex糊剂+牙胶尖组和Vitapex糊剂组术后1,3d疼痛发生率比较差异无显著性意义(P>0.05)。3组患者术后7d疼痛发生率比较差异无显著性意义(P>0.05)。②术后1年疗效评价:Vitapex糊剂+牙胶尖组成功率高于Vitapex糊剂组、常规根管充填材料+牙胶尖组(分别为89.41%,72.94%,76.19%),差异均有显著性意义(χ2=7.55,4.85,P<0.05)。结论:Vitapex糊剂是一种理想的一次性根充材料,与牙胶尖配合使用是其最适宜方式,其疗效高于常规充填剂。
AIM： To evaluate the post-obturation pain and curative effect of single-visit root canal treatment on teeth using Vitapex paste. METHODS： A total of 254 cases （254 teeth） with chronic apicitis were selected from Department of Stomatology, Sichuan Provincial People＇s Hospital from April 2004 to April 2005, with the approval of ethnic committee and the informed consents of patients. They were divided into 3 groups randomly： group A （85 teeth） was injected with Vitapex paste and gutta-percha; group B （85 teeth） were injected with Vitapex but without gutta-percha; In group C （84 teeth）, root canals were filled with routine materials. Evaluation： ①1, 3, 7 days after operation, post-obturation pain was ranked as none, mild pain （a little pain, no affection on the daily life）, moderate pain （obvious pain, affecting daily life within the tolerance）, severe pain （intensive pain beyond the tolerance, needing emergent management）.②The curative effect was satisfying according to the criteria： no symptom and physical sign, normal articulation function, close canal obturation and disappeared periapex transparent area in X ray film, normal periodontal membrane space, good articulation function, periapex transparent area shortening and thickening in X ray film. RESULTS： ③The incidence of post-obturation pain 1 and 3 days after operation in group C was significantly higher than that in groups A and B （10.59%, 12.94%, 28.57%; 8.24%, 7.06%, 21.43%, χ2=8.69, 6.29, 5.86, 7.16, P〈 0.05）. There was no significant difference between group A and group B （P 〉 0.05）.②One year later, the success rate of group A was higher than that of groups B and C significantly （89.41%, 72.94%, 76.19%, χ2=7.55, 4.85, P〈 0.05）. CONCLUSION： Vitapex paste is a kind of ideal material for single-visit root canal treatment on teeth with chronic apicitis, and its combination with gutta-percha is the best way to be applied.
