Q

Who interprets radiographs?

A

Any dental professional with training in interpretation can examine films.

Involves the identification of:
1. Normal anatomy

Q

What is the difference between interpretation and diagnosis?

A
  1. Interpretation - An explanation of what is viewed on a radiograph
  2. Diagnosis - The identification of disease by examination or analysis
  3. The final interpretation and diagnosis are the responsibilities of the dentist.
  4. Dental hygienists and dental assistants are restricted by law from rendering a diagnosis
  5. RDH can only describe what is seen on a radiograph without implying a diagnosis

Q

When and where are radiographs interpreted?

A
  1. Immediately after mounting in the presence of the patient
  2. Examination may be necessary to obtain additional information/ confirm a problem.

Q

Describe the importance of interpretation in patient education

A

Used as an education tool
1. The patient may be educated through discussion of normal findings on dental radiographs
2. Specific problems and areas of concern may be identified and discussed

Q

What is descriptive terminology?

A
  1. Terms used to describe: the appearance, location, and size of a lesion
  2. This information should be documented for all lesions viewed radiographically
  3. Standard DT means Intelligent and easy communication amongst dental professionals - Eliminates the chance for miscommunication/Confirms films were reviewed

Q

What is needed for the dentist to make a diagnosis?

A

The patient’s medical and dental history, clinical findings, signs and symptoms, laboratory tests, and biopsy results are necessary for the dentist to make a definitive diagnosis

Q

Describe radiolucent

A
  1. That portion of a processed radiograph that is dark or black
  2. Caries appears radiolucent because the area of tooth with caries is less dense than surrounding structures

Q

Radiopaque

A
  1. That portion of a processed radiograph that appears light or white
  2. A metallic restoration appears radiopaque because it is very dense and absorbs the radiation

Q

Describe Unilocular radiolucent lesions

A
  1. One compartment
  2. Tend to be small and nonexpansile
  3. Have borders that may appear corticated or noncorticated on radiograph.
  4. Borders: well defined / ill-defined, regular/ irregular

Q

How does a Unilocular lesion with corticated borders appear?

A
  1. The lesion exhibits a thin, well-demarcated radiopaque rim of bone at the periphery
  2. Usually indicative of a benign, slow-growing process

Q

How does a Unilocular lesion with non-corticated borders appear?

A

The lesion does not exhibit a thin radiopaque rim of bone at the periphery
2. The periphery appears fuzzy or poorly defined
3. May represent either a benign or a malignant process

Q

Describe Multilocular radiolucent lesions

A
  1. A lesion that exhibits multiple radiolucent compartments
  2. Frequently expansile
  3. Typically benign lesions with aggressive growth potential
17
Q

How would you describe the location of a lesion?

A
  1. Periapical location
  2. Inter-radicular location
  3. Edentulous location
  4. Pericoronal location
  5. Alveolar bone loss
18
Q

Describe the periapical location

A
  1. A lesion located around the apex of a tooth
  2. Example - Periapical cyst secondary to pulpal necrosis
19
Q

Describe the inter-radicular location

A
  1. A lesion located between the roots of adjacent teeth
  2. Example - Lateral periodontal cyst
20
Q

Describe the edentulous location

A

A lesion located in an area without teeth

21
Q

Describe the pericoronal location

A
  1. A radiolucent lesion located around the crown of an impacted tooth
  2. Example - Dentigerous cyst
22
Q

How are sizes of lesions noted on radiographs?

A
  1. Can vary from several millimeters in diameter to several centimeters in diameter.
  2. Small, medium, large
  3. Can be measured on a radiograph with a millimeter ruler
23
Q

What terms are used to describe a radiopaque lesion?

A
  1. focal opacity
  2. target lesion
  3. multifocal confluent
  4. irregular, ground glass, or mixed lucent-opaque

*Radiopaque lesions occur not only in bone but in soft tissue as well

24
Q

Describe focal opacity

A
  1. A well-defined, localized radiopaque lesion on a radiograph
  2. Example - Condensing osteitis
25
Q

Describe target lesion

A
  1. A well-defined, localized radiopaque area surrounded by a uniform radiolucent halo
  2. Example - Benign cementoblastoma
26
Q

Describe Multifocal Confluent

A
  1. Multiple radiopacities that appear to overlap or flow together
  2. Multifocal confluent radiopacities involving multiple quadrants of the jaws usually represent benign fibro-osseous disorders
  3. Example - Osteitis deformans, florid osseous dysplasia
27
Q

Describe Irregular Ill-Defined

A
  1. A radiopacity may exhibit an irregular, poorly defined pattern
  2. May represent a malignant condition
  3. Examples - Osteosarcoma and chondrosarcoma
28
Q

Describe ground glass

A
  1. A granular or pebbled radiopacity that resembles pulverized glass
  2. Often said to resemble the appearance or texture of an orange peel
  3. Examples - Fibrous dysplasia, osteitis deformans, and osteopetrosis
29
Q

Describe Mixed Lucent-Opaque

A
  1. Exhibits both a radiopaque and a radiolucent component
  2. Often represent calcifying tumors
  3. Example - Compound odontoma
30
Q

Describe soft tissue opacity

A
  1. Appears as a well-defined, radiopaque area located in soft tissue
  2. Examples - Sialolith, Calcified lymph node
