【摘要】 目的:比较Vitapex糊剂作为根管消毒药物治疗较大根尖囊肿的临床疗效。方法:将临床诊断为根尖囊肿的52例患牙随机分为两组,每组26例,以氢氧化钙糊剂为对照组,根管内封氢氧化钙1周后即AH-plus糊剂和牙胶尖充填,6个月和12个月复诊。Vitapex糊剂为实验组,根管内封Vitapex 6个月,复诊时再以AH-plus糊剂牙胶尖充填,继续观察6个月,即12个月时复诊。比较6个月复诊及12个月复诊时实验组及对照组的治疗效果。结果:6个月复诊时,氢氧化钙组的成功率为73.1%,Vitapex组的成功率为76.9%。两组间无显著性差异。12个月复诊时,氢氧化钙组的成功率为69.2%,Vitapex组的成功率为92.3%,两组间有显著性差异。结论:根尖囊肿采取Vitapex多次封药,可以促进根尖病变愈合,提高疗效。更多还原

【Abstract】 Objective:To evaluate the clinical effect of vitapex in the treatment of large periapical cyst.Method:A total of 52 teeth that diagnosised as periapical cyst were divided into 2 groups with each group of 26 teeths.In control group,after 1w intracanal medicament of calcium hydroxide,the canals have been filled with AH-plus and gutta-percha and then followed-up at 6 m,12 m.In experimental group,after 1 m,3 m,6 m of intracanal medicament of Vitapex,the canals have been filled with AH-plus and gutta-percha at the 6 m-follow up and then observed for next 6m,that is the 12 m-follow up.Compare the clinical effect of vitapex and calcium hydroxide in the 6m-follow up and 12 m-follow up.Result:The success rate of calcium hydroxide group and Vitapex paste group are 73.1 % and 76.9 % at 6 m-follow,69.2 % and 92.3 % at 12 m-follow up separately.A significant difference can be found in 12 m-follow up and no difference in 6m-follow up.Conglusion:In large periapical cyst,many-visit of Vitapex paste as intracanal medicament help to facilitate the healing of pereiapical diseases.更多还原
