摘要/Abstract

摘要： 目的对年轻恒牙完全脱出再植预后的相关因素进行分析。方法收集2008?2011年门诊就诊的46例50颗诊断为完全脱出的年轻恒牙，按照牙外伤指南再植后随访6个月?2年，对储存方式，再植时间，牙根发育程度，牙髓摘除的时间，预后等因素进行相关性分析。结果 50颗年轻恒牙中有74%为干燥保存，70%伤后超过60 min就诊，牙根发育越少（Nolla 7期），牙髓坏死需要观察的时间越长，牙根发育越接近完成（Nolla 9期），牙髓坏死出现的越快。结论年轻恒牙完全脱出时牙根发育越少，口外干燥时间越短，预后越好。

Abstract: [Abstract] Objective To analyze the related factors of the prognosis after replantation of the avulsed young permanent teeth. Methods 50 avulsed young permanent teeth of 46 patients from the clinic which were replanted based on the guideline of the teeth injuries were observed, from 2008 to 2011, about the storage pattern, replantation time, the development level of the root, time of pulp remove and the prognosis. The observing period lasted from 6 months to 2 years. Results 74% of 50 teeth were in dry storage and 70% came to clinic over 60 min after injury. The less root development was (Nolla 7), the longer pulp necrosis needed to be observed. The closer root development was to completion (Nolla 9), the faster dental pulp necrosis appeared. Conclusion The prognosis is better in the condition of shorter root development and shorter time of dry storage in the young permanent teeth avulsion.
