  1. what three characteristics are used when describing a lesion?
    • appearance
    • location
    • size
  2. why do you want to use descriptive terminology?
    communicate intelligently, using common language and eliminate the chance for miscommunication
  3. _______ is done for legal reasons
    documentation
  4. how is a descriptive terminology different than a diagnosis
    descriptive terminology is what is seen on a radiograph and diagnosis is done by considering other sources besides radiographs
  5. what things are considered with a diagnosis?
    • medical and dental history
    • clinical findings
    • signs and symptoms
    • lab tests
    • biopsy result
  6. an image that is produced on photosensitive film
    radiograph
  7. beam of energy that has power to penetrate substances and to record shadow images on photographic film
    xray
  8. portion of processed radiograph that is dork or black, structures lack density and permit the passage of xray beam with little or no resistance
    radiolucent
  9. the portion of a processed radiograph that appears light or white, structures are dense and absorb or resist the passage or the xray beam
    readiopaque
  10. what are the five terms used to describe the appearance of a radiolucent lesion
    • unilocular radiolucent lesion
    • multilocular radiolucent lesion
    • moth-eaten pattern
    • multifocal pattern
    • widened periodontal ligament
  11. for a unilocular radiolucent lesion what are two examples?
    • corticated
    • noncorticated
  12. cortex borders exhibit thin, well demarcated radiopaque rim of bone at periphery. Benign and slow growing.
    corticated (unilocular radiolucent lesion)
  13. no border appears fuzzy and poorly defined, benign or malignant
    noncorticated (unilocular radiolucent lesion)
  14. multilocular radiolucent lesions are _____ and usually ______
    • larger
    • corticated
  15. t/f multilocular radiolucent lesions are expansile and displace buccal and lingual bone plates.
    true
  16. t/f multilocular radiolucent lesions are usually benign and show aggressive growth
    true
  17. what are five descriptive terms for location
    • periapical
    • inter-radicular
    • edentulous zone
    • periocoronal
    • alveolar bone loss
  18. documentation of size is ______ ______
    very important
  19. what do you measure the size of a lesion in?
    mm or cm
  20. ______ indicates type of treatment
    size
  21. what are five examples of structures that resist the passage of xray? What will the look like on a radiograph?
    • osseous tissue
    • cartilage
    • enamel
    • dentin
    • cementum
    • will appear radiopaque
  22. what are seven terms used to describe the appearance of a radiopaque lesion?
    • focal opacity
    • target lesion
    • multifocal confluent
    • irregular ill defined
    • ground glass
    • mixed lucent-opaque
    • soft tissue opacity
  23. what are four terms used to describe location of a radiopaque lesion
    • periapical location
    • inter-radicular locaiton
    • edentulous zone
    • pericoronal location
  24. t/f to document the size of a lesion on a radiograph you can use the perio probe right on the radiograph?
    true
