2 most popular and important tooth fracture classification disscussed

Tooth fractures can occur due to various reasons like trauma, decay, or weak tooth structure.

ELLIS AND DAVEY CLASSIFICATION OF TOOTH FRACTURE

Ellis and Davey in 1970 proposed a classification system for tooth fractures based on the extent of damage to the tooth structure.

Class 1: Simple fracture of the crown involving little or no dentin

Class 2: Extensive fracture of the crown involving considerable dentin but not pulp

Class 3: Extensive fracture of the crown involving considerable dentin, and exposing the dental pulp

Class 4: The traumatized tooth which becomes nonvital with or without loss of crown

Class 5: Teeth lost as a trauma

Class 6: Fracture of the root with or without loss of crown structure

Class 7: Displacement of the tooth without fracture of crown or root

Class 8: Fracture of the crown en masse and its replacement

Class 9: Traumatic Injury to primary dentition

BENNETT CLASSIFICATION OF TOOTH FRACTURES

Bennett classified tooth fractures into five types based on the extent of the fractured teeth. Bennett’s tooth fracture classification is the second most popular after Ellis and Davey’s classification.
