Radiology6: Dental Trauma Lecture Notes

A set of 50 flashcards covering key terms and definitions related to dental trauma.

Dental Trauma

Injury to the teeth and surrounding structures.

Etiology of Dental Trauma

Common causes include falls (65%), sports injuries, cycling accidents, motor vehicle accidents, and physical violence.

Luxation

Dislocation of a tooth or teeth.

Concussion

Injury where the tooth remains stable but experiences bleeding in the gingiva due to forces applied.

Subluxation

A condition where the tooth is mobile without displacement. Widened PDL

Intrusion

Tooth is pushed into the bone, depth of which affects prognosis.

Extrusion

Tooth is partially displaced from its socket.

Avulsion

Complete ejection of a tooth from the socket.

Resorption

Long-term effects of trauma leading to the breakdown of tooth roots.

Ankylosis

The fusion of the tooth root to the alveolar bone.

Fractured Tooth

Damage to the tooth structure including enamel, dentin, and possibly pulp.

Chipped Tooth

Fracture confined to enamel or dentin; pulp remains unaffected.

Complete AVulsion

When a tooth is completely displaced and may be replanted.

Partial Avulsion

Tooth is partially displaced but remains in the socket.

Subsequent Treatment

Follow-up treatment necessary after initial injury assessment.

Flexible Splint

A device used to stabilize teeth after trauma.

Immediate Treatment

Primary care given to a tooth after trauma occurs.

Pulp Vitality Testing

Assessing the health of the pulp after dental trauma.

Dental Radiographs

X-rays used to assess trauma to the teeth and jaw.

Gingival Laceration

Tearing of the gum tissue often resulting from dental trauma.

Periapical Radiograph

An X-ray that shows the whole tooth, its roots, and surrounding bone.

Lateral Luxation

Lateral displacement of teeth usually requiring repositioning.

Maxillofacial Trauma

Injuries affecting the maxilla and facial bone structures.

Alveolar Fracture

Fracture involving the alveolar bone that supports the teeth.

Mandibular Fracture

Break in the lower jawbone.

Condylar Fracture

Fracture of the condylar neck in the mandible.

Vertical Root Fracture

Fracture that runs vertically along the length of the root.

Horizontal Root Fracture

A fracture that runs horizontally across the root of a tooth.

Complicated Crown Fracture

A fracture that exposes the pulp tissue.

Uncomplicated Crown Fracture

A fracture that does not expose pulp.

Root Canal Treatment (RCT)

Endodontic treatment to remove infected pulp.

Storage Medium for Avulsed Tooth

Ideal solutions such as milk, HBSS, and saline to preserve a tooth until replantation.

Dental Guidelines

Protocols developed by associations for the treatment of dental injuries.

Bleeding in Gingiva

Common symptom after tooth concussion.

Intraoral Assessment

Clinical examination of the oral cavity for injuries.

Emergency Management

Procedures followed immediately after a dental trauma.

Ortho Repositioning

Orthodontic methods to move teeth back to proper alignment.

Chipping

Minor fracture of enamel.

Open Fracture

Fracture with exposure to the oral environment.

Bone Fracture

Fracturing of the bone surrounding the teeth.

Surgical Stabilization

Using surgical techniques to stabilize fractured bones.

CBCT

Cone Beam Computed Tomography used for detailed imaging of dental structures.

Displacement

Movements of teeth from their normal position following trauma.

Crown Fracture

Fracture involving loss of crown structure.

Vertical Fracture Identification

Detection based on characteristic patterns in radiographs.

Trauma Guidelines

Standards established for managing dental trauma cases.

Sports Injuries

Common cause of dental trauma among active individuals.

Concussion assessment 

Take a PA. Test vitality with cold and retest after a period to see overall vitality. 

subluxation follow up if:

discoloration pain and continued mobility 

chipped tooth

only enamel and dentin

can be filled

can be crowned depening

fractured tooth 

root canal if into pulp

vitality test if no pulp availible 

can repair with bonding or crown.

root fracture

vertical or horizontal

outcome depends on location and mobility

mobility means extract

horizontal root fracture

vertical fracture

vertical root fracture

not always visualized but shows j shape lucency

extraction typical

imaging for fractures

PA to CBCT

alveolar fracture

alveolar fracture

difficult to visualize on 2D

bone with tooth fractured

fractured maxilla
