Preguntas en Español (Questions in Spanish!): Root Resorption
The most common resorption classification is by Heithersay (1999). He classified invasive cervical root resorption lesions based on their size and extension into root structures.
Class 1: Small, cervical area of the root involving dentin only
Class 2: Slightly larger, penetrating more into dentin and closer to the coronal pulp
Class 3: Larger, less defined lesion. Extending into the coronal third of the root.
Class 4: Large lesion extending beyond the coronal third of the root.
I hope this helps! :)
