WHO has given a classification which does not pertain to tooth only but also the soft tissue injuries and facial skeletal injuries. It is discussed as following

a) Soft Tissues

1) Lacerations

2) Contusions

3) Abrasions

b) Tooth Fractures

1) Enamel Fractures

2) Crown fractures – uncomplicated (no pulp exposure)

3) Crown fractures – complicated (with pulp exposure)

4) Crown root fractures

5) Root fractures.

c) Luxation Injuries

1) Tooth concussion

2) Subluxation

3) Extrusive luxation

4) Lateral luxation

5) Intrusive luxation

6) Avulsion.

d) Facial Skeletal Injuries

1) Alveolar Process – maxilla/mandible

2) Body of maxillary/mandibular bone

3) Temporomandibular joint

Now you know about the WHO classification and realise that it is an extensive layout of dento-facial injuries. Let us now go through the final points of tooth fractures and luxation injuries.
