【摘要】：目的:探讨ProTaper专用牙胶及普通大锥度牙胶在临床中的应用方法及效果。方法:离体单根管恒牙132个,粗、细根管各66个,分别随机分为6组,每组10个,余12个分别作为阳性和阴性对照;比较普通大锥度牙胶尖(Genl-主尖)和ProTaper专用牙胶尖(Pro-主尖)在根管充填效率和封闭性方面的差异;结合染料渗透法和透明标本法,测量根尖微渗漏长度以评价各组根尖封闭能力。结果:细根管Pro-主尖和Genl-主尖在充填时间及根尖封闭性方面无显著差异;粗根管:使用Pro-主尖进行冷侧压充填比使用Genl-主尖更节省充填时间,但两者根尖封闭性方面无显著差别,粗大根管用热牙胶充填法更节省时间;使用Pro-主尖或Genl-主尖进行单尖充填的根尖封闭效果均不佳。结论:ProTaper专用牙胶尖不适合进行单尖充填;对于较粗大根管进行冷侧压充填,使用ProTaper专用牙胶较使用普通锥度牙胶更节省充填时间。
[Abstract]:Objective: to investigate the clinical application and effect of ProTaper special gum and common large taper gum. Methods: 132 permanent teeth with isolated single root canal, 66 teeth with coarse root canal and 66 permanent teeth with fine root canal were used. They were randomly divided into 6 groups with 10 in each group and the remaining 12 as positive and negative controls. The differences of root canal filling efficiency and sealing were compared between the common large taper (Genl- main cusp) and the ProTaper special dental cusp (Pro-main tip). Combined with dye permeation method and transparent specimen method. Results: there was no significant difference in filling time and apical closure between Pro-main tip and Genl-main tip of fine root canal. Thick root canal: cold lateral filling with Pro-main tip was more efficient than that with Genl- main tip, but there was no significant difference in sealing of root tip between the two groups, and hot gum filling with thick root canal could save more time. Using Pro-main tip or Genl-main tip for single-tip filling was not effective. Conclusion the special gum tip of ProTaper is not suitable for single-tip filling. For larger root canal filling with cold side pressure, the filling time was saved by using ProTaper special gum than using common taper gum.

【正文快照】： 根管充填的目的是严密封闭全根管系统,杜绝再感染。现有的根充方法有许多种:侧压法、垂直加压法、注射热牙胶技术、热塑牙胶技术等[1]。高效快捷且根尖封闭性良好的根管充填方法一直是临床医生不断探索的方向。但到目前为止,没有一种根充方法能够高效地封闭全根管系统,彻底
