Abstract

Dilaceration is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth. Crown dilaceration of permanent tooth occurs due to the non-axial displacement of the already formed hard tissue portion of the developing crown at an angle to their longitudinal axis due to trauma to the primary predecessors. Thus endo-aesthetic management of such teeth helps in maintaining morphology as well as aesthetics in a growing child. This article depicts two cases of severely dilacerated crown.

摘要

牙折是一种发育异常的结果,其中牙齿的冠部和根部之间的轴向倾斜发生了突然变化。恒牙的冠部牙折是由于发育中的冠部已形成的硬组织部分因乳牙前身受到创伤而相对于其纵轴呈角度的非轴向位移所致。因此,对这类牙齿进行牙髓美学管理有助于在成长中的儿童中维持形态和美观。本文描述了两例严重冠部牙折的病例。
