Trauma: Section A

Dentoalveolar trauma refers to injuries affecting the teeth and their supporting structures. The anatomical structures involved include the teeth themselves, the alveolar bone of the maxilla and mandible, and the adjacent soft tissues such as gingiva and mucosa.

Periodontal injuries are most common in primary dentition because children have softer bone. This softer bone and less developed roots in primary teeth mean that when trauma occurs, the teeth are more likely to move within the socket, leading to periodontal injuries rather than fractures of the harder dental tissues.

In permanent dentition, hard tissue injuries, such as enamel or dentin fractures, are the most common, unlike primary dentition where periodontal injuries are more frequent. Tooth fracture is also more likely to be observed in permanent dentition injuries compared to primary teeth.

<p>Complex dentoalveolar injuries involve a combination of both hard tissue injuries (like fractures of enamel, dentin, or cementum) and periodontal tissue injuries (affecting the supporting structures of the teeth). They are less common in primary dentition likely because the softer bone and more mobile teeth in children often result in injuries being dissipated through periodontal structures rather than causing combined hard and soft tissue damage.</p> Signup and view all the answers

<p>Two distinct categories of traumatic events are accidents and interpersonal violence. Accidents include events like falls, sports injuries, bicycle accidents, and road traffic accidents. Interpersonal violence is represented by 'Non accidental injury', suggesting intentional trauma.</p> Signup and view all the answers
