目的讨论Vitapex糊剂在治疗乳牙根尖周炎的疗效。方法将150例患儿194患牙随机分为实验组和对照组。实验组采用Vitapex糊剂填充,对照组采用氧化新丁香油糊剂填充。结合X线检查以及随访结果,评价术后反应、超充吸收率和疗效。结果 2组在术后反应与超充吸收率方面有统计学差异(P<0.05),但是在最终疗效上差异不显著(P>0.05)。结论虽然Vitapex糊剂在治疗乳牙根尖周炎的成功率与氧化新丁香油糊剂治疗差异不显著,但是使用Vitapex可以获得更好的术后反应和超充吸收效果,因此无疑是一种相对较优的治疗方法。 Objective To discuss the efficacy of Vitapex paste in the treatment of apical periodontitis of deciduous teeth. Methods One hundred and fourteen teeth of 150 children were randomly divided into experimental group and control group. The experimental group was filled with Vitapex paste, while the control group was filled with the oxidized new clove paste. Combined with X-ray examination and follow-up results, postoperative response, supercharged rate and efficacy were evaluated. Results There was a significant difference (P <0.05) between postoperative response and supercharged absorption rate in the two groups, but there was no significant difference in final efficacy (P> 0.05). Conclusion Although the success rate of Vitapex paste in the treatment of periapical periodontitis is not significantly different from that of the new drug, the use of Vitapex can get better postoperative response and supercharged absorption, so it is undoubtedly a relative Better treatment.
