DHE 116 quiz Lecture 4 Mounting Interpretation and Normal Radiographic Anatomy

The flashcards below were created by user dentalhygiene on FreezingBlue Flashcards.

  1. What does mounting do?
    • View and interpret
    • Decreases the chance of error
    • Comparison
    • Less handling
    • Easy to store
    • Patient education
  2. Identification dot: Convex or Concave
    • If packet is placed correctly raised portion of the dot faces the x-ray tube
    • Used to determine right or left side of pt. when mounting
    • Herring bone = backwards film
  3. Film mounting methods
    • Lingual method not used any more (reverse of the labial)
    • Labial Mounting Method (ADA accepted) (“it is your mouth”)
    • Mounting the embossed dot as convex
    • Viewer is reading as if standing facing the pt.
    • What the viewer sees on the right is the patients left
  4. Film mounting procedure
    • Mount protects traditional films
    • Embossed dot is the SAME for all films (hopefully “dot UP”)
    • Film size as orientation: vertical or horizontal

    • –This will decipher anterior or posterior
    • Mount BWX 1st
    • Use restoration(s) as landmarks
    • Separate anterior from posterior
    • Maxillary from mandible
  5. General rules of Anatomy
    • Roots and crowns of Max ant teeth are longer and larger than mand.
    • Canine have longest roots
    • Max molars have 3 roots
    • Mand. Have 2 divergent roots
    • Most roots curve toward the distal
    • Large radiolucent areas:
    • Nasal fossa
    • Max sinus
    • Mand. Has a distinct upward curve = “smile” or curve of spee
  6. Viewing the Radiographs
    Document / Collaborate / Confirm
    • 1. Presence of or absence of teeth
    • 2. Tooth morphology ( or amorphic)
    • 3. Normal and abnormal eruption patterns
    • 4. Suspected pathology
    • 5. Deviations from “normal”
    • 6. Caries – incipient, moderate & severe
    • 7. Periodontal conditions
    • 8. Dental materials
  7. Interpretation vs. Diagnosis
    • Radiographs can be interpreted by all staff
    • Dentist is only one that can “diagnose”
    • Interpretation is the reading and explaining of what is observed
    • Diagnosis is the determination of the nature and the identification of an abnormal condition or disease
  8. Who is legally able to diagnose?
    Dentist is only one that can “diagnose”
  9. Who is legally able to interpret?
    Radiographs can be interpreted by all staff
  10. Radiopaque
  11. Radiolucent
  12. _____the portion of the maxilla or mandible that surrounds & supports teeth.
    Alveolar Process
  13. Components of Alveolar process is
    lamina dura
  14. Alveolar Bone consist of?
    • Cortical bone: compact/dense. bone=extreme white
    • Cancellous (spongy) bone: bulk of inner bone=shades of grey
    • Trabeculae (honeycomb & part of cancellous)fat, blood & bone cells=more grey-black if thinner walls
    • Image Upload
    • Image Upload
  15. All bone tissue appears____
    radiopaque w/ variations
  16. ___ is the edge of the alveolar bone, the height or level gives an indication of bone loss and periodontal disease
    • Alveolar crest

  17. Anterior nasal spine

  18. Apical foramen/Cementum
    Image Upload
  19. Condyle/Mandibular Notch

  20. _____ is marked prominence or projection of bone
    • coronoid process
    • Image Upload
    • Image Upload
  21. _____ are Attachment sites for the genioglossus and geniohyoid muscles.Ring shaped
    • Genial tubercles

    • Image Upload
  23. Incisive Foramen:
    • Image Upload
    • Image Upload
  24. Intersection of the maxillary sinus and the nasal cavity ?
    • Inverted Y formation
    • Image Upload
  25. The Inverted Y formation is Visible on what x-ray?
    • Maxillary Cuspid
