摘要/Abstract

摘要： 年轻恒牙萌出后牙根继续发育,但是在牙根发育过程中,由于龋病、牙外伤、牙齿发育异常等可引起年轻恒牙牙髓感染或坏死,使牙根的发育受阻,导致根尖孔粗大、根管壁薄。年轻恒牙的根尖独立于主根管单独发育,是一种特殊的牙根发育类型。该文通过文献回顾,分析了根尖独立发育可能形成的原因,为临床医生在诊疗时提供一定的思路。

Abstract: Root development will continue after immature permanent tooth eruption. However, during this period if the pulp is inflamed or necrosed due to caries, dental trauma or teeth dysplasia, root formation will be interrupted, which results in an open apex and thin root canal wall. It has been reported that apical development of immature permanent teeth is independent of main root canal, which is a special type of root development. In this paper, we reviewed literature and analyzed possible causes for the separated root tip formation of immature permanent tooth, which could provide some suggestions for clinicians to make correct preventive and therapeutic decisions.

Key words: young permanent tooth, deparated root tip, infection, dental trauma, tooth dysplasia
