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.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
