Radiology PP-T Interpretation of Trauma

  1. What is a Class I fracture
    enamel only
  2. What is a Class II fracture
    dentin not pulp
  3. What is a Class III fracture
    extensive injury including pulp
  4. What is a Class IV fracture
    fracture below the CEJ
  5. What is more common a crown fracture or a root fracture
    crown fracture
  6. Root fractures are most often in the ______ region
    maxillary centrals
  7. Prognosis is more favorable if the fracture occurs
    closer to the apex (treated w/RCT)
  8. Root fractures are more common in _____ teeth due to _______
    • RCT
    • loss of blood supply; more brittle
  9. Fractures occur in _______ more than any other bone in the face and the radiograph of choice for this fracture is a
    • mandible
    • Pan
  10. What is a luxation tooth injury, what are the types, and what is the radiograph of choice
    • Abnormal displacement from alveolar bone
    • Intrusion (into bone)
    • Extrusion (out of bone)
    • PA
  11. What is an avulsion tooth injury
    Complete displacement from alveolar bone
  12. What are the two types of avulsion
    • Direct trauma: force is applied directly to the tooth
    • Indirect trauma: force causes maxilla and mandible to strike against each other
  13. Concussion is ________ and will radiographically show a
    • trauma causing injury to supporting structures without abnormal loosening or displacement of teeth
    • see a widening of the PDL space (usually apically)
  14. Facial Fractures are usually in the
    Zygoma and mandible
  15. In Jaw Fracture Diagnosis Films should be taken from several different angles, preferably at _________ to one another
    right angles
  16. Favorable Mandibular Fractures
    muscle action reduces fracture
  17. Unfavorable Mandibular Fractures
    muscle attachments pull the displaced fragments out of their normal position
  18. Common Sites: Mandibular Fractures
    • Condyles
    • Body
    • Angle
  19. Causes: Mandibular Fractures
    • Assault
    • Auto accidents
    • Falls
    • Sports injury
  20. Simple Bone Fracture
    fracture that causes little or no damage to the surrounding soft tissue; overlying tissue is intact
  21. Complex Bone Fracture
    closed fracture in which the soft tissue surrounding the bone is severely damaged
  22. Compound Bone Fracture
    fracture communicates w/outside environment
  23. Comminuted Bone Fracture
    bone is splintered, crushed or broken into fragments. May be simple or compound
  24. Greenstick Bone Fracture
    bone bends and cracks instead of breaking into separate pieces; incomplete fracture (common in children)
  25. Most common Fractures of the Condyle
    below the condylar head
  26. Le Fort I Fractures of the Face/ Maxilla
  27. Le Fort II Fractures of the Face/ Maxilla
  28. Le Fort III Fractures of the Face/ Maxilla
    Craniofacial Disjunction
  29. Mandibular fractures are more likely on ______ ages ________
    • males
    • 16 to 35
