INTRODUCTION
Internal root resorption is the loss of hard tissue of the tooth from the pulpal surface of the root canal space. This pathologic condition is characterized by damage to the organic sheath, loss of predentin, and odontoblastic layer leading to demineralization of hard tissue of the tooth.
CONTEXT
Internal root resorption.
AIMS
The aim of this article is to classify internal resorptive lesions to distinguish the extent of resorption at various levels as seen in the tooth.
SUBJECTS AND METHODS
Internal resorption is less commonly diagnosed as compared to external resorption. Internal inflammatory resorption has been classified depending on the inflammatory process of the tooth as transient or persistent. There is a need for classification of the extent and location of the resorptive lesion. Hence, this article is focused on the classification of internal resorption based on the location of the resorptive site and the extent of tissue involved.
CONCLUSIONS
There is a need for classification of the extent and location of the resorptive lesion. Hence, this article is focused on the classification of internal resorption based on the location of the resorptive site and the extent of tissue involved.
引言
牙根内吸收是指根管空间牙髓面的牙齿硬组织丧失。这种病理状况的特征是有机鞘受损、前期牙本质丧失以及成牙本质细胞层受损，从而导致牙齿硬组织脱矿。
背景
牙根内吸收。
目的
本文的目的是对牙根内吸收性病变进行分类，以区分在牙齿中不同层面所见的吸收程度。
对象与方法
与牙根外吸收相比，牙根内吸收的诊断较少见。根据牙齿的炎症过程，将内炎性吸收分为短暂性或持续性。需要对吸收性病变的范围和位置进行分类。因此，本文重点基于吸收部位的位置和受累组织的范围对牙根内吸收进行分类。
结论
需要对吸收性病变的范围和位置进行分类。因此，本文重点基于吸收部位的位置和受累组织的范围对牙根内吸收进行分类。
