Dental trauma refers to trauma (injury) to the teeth and/or periodontium (gums, periodontal ligament, alveolar bone), and nearby soft tissues such as the lips, tongue, etc. The study of dental trauma is called dental traumatology.
Dental injuries include:
Injuries to supporting bone
This injury involves the alveolar bone and may extend beyond the alveolus. There are 5 different types of alveolar fractures:
Trauma injuries involving the alveolus can be complicated as it does not happen in isolation, very often presents along with other types of tooth tissue injuries.
Signs of dentoalveolar fracture:
- Change to occlusion
- Multiple teeth moving together as a segment and are normally displaced
- Bruising of attached gingivae
- Gingivae across the fracture line often
