Study Notes

Dental Injuries - Etiology

Direct trauma often results from collisions in contact sports.
Mouthpieces are crucial to prevent dental injuries.
Most common during the first 12 years of life, with traumatic dental injuries being prevalent.

Medical History for Dental Injuries

Important to note the circumstances surrounding the injury, including time and location.
Assess the patient's overall health and any medications taken.
Symptoms suggesting more severe injuries must be documented.
Previous management actions taken prior to clinic visit should be recorded.
Proper storage methods for avulsed teeth need to be established.

Examination Principles

Begin examination externally, progressing inward.
Look for missing tooth fragments or prosthetic components to assess inhalation risk.
Evaluate pulp exposure, noting size and location.

Types of Fractures

Blow to the chin can lead to crown-root fractures in molars and premolars.
Teeth displacement and avulsion assessed through visual examination, occlusion checks, and radiographs.

Complications with Primary Teeth

Displaced primary teeth can hinder the development of permanent successors.
Palpation from a vestibular approach can help identify displacement issues.

Occlusion Changes

Jaw fractures or alveolar process fractures can impact occlusion.
Alveolar fractures show mobility in adjacent teeth when tested.

Mobility and Radiographic Examination

Radiographic examination is needed to differentiate between luxation injuries and root fractures.
Various imaging techniques include dental films, panoramic imaging, CT scans, and cone-beam CT.

Dental Injury Classifications

Classifications for injuries are available in specific pediatric resources.

Treatment of Dental Fractures

Infraction usually requires no treatment.
Uncomplicated fractures can be treated with smoothing and composite restoration.
Complicated fractures involve pulpotomy, pulp extirpation, or apexification based on the condition of the pulp and root apex.

Management of Various Dental Conditions

Uncomplicated crown-root fractures require removal of coronal fragments and restoration.
Complicated crown-root fractures necessitate extraction if non-restorable, or either pulp extirpation or superficial pulp amputation if restorability is uncertain.
Root fractures require repositioning and splinting; root canal treatments are delayed to allow for potential pulp healing.
Concussions require no treatment; subluxations use flexible splints for comfort.

Treatment for Displacement and Avulsion

Lateral luxation involves manual repositioning and splinting for four weeks; monitor pulpal health.
Extrusion should be manually repositioned and stabilized as well.
Intrusion treatment varies based on root formation; spontaneous re-eruption is encouraged in incomplete roots, while completed roots typically necessitate orthodontic treatment or surgery.
Immediate avulsion management includes reassurance, tooth cleaning, and replantation if possible, or proper storage in milk or saline.

Clinic Procedures for Avulsed Teeth

After replanting an avulsed permanent tooth, clean the area, and apply a splint.
If avulsed outside the socket with prolonged dry time, consider root canal treatment, and monitor for root resorption.
For primary teeth, treatment differs; they should not be replanted, especially if impacting permanent tooth development.

Complications Post-Injury

Pulpar complications include canal obliteration, necrosis, and internal root resorption.
Periodontal complications can lead to infection-related resorption or dentoalveolar ankylosis.
