Answers Already Passed
What is the primary function of a radiograph in dental hygiene?
✔✔ To visualize and assess the teeth, bone structures, and surrounding tissues for diagnostic
purposes.
What does the term "bitewing radiograph" refer to?
✔✔ A type of dental X-ray that shows the upper and lower teeth in one area of the mouth to
assess dental decay between teeth.
How is a panoramic radiograph different from a bitewing radiograph?
✔✔ A panoramic radiograph provides a full view of the entire mouth, including the jaws, teeth,
and surrounding structures, while a bitewing focuses on a smaller area.
What is the purpose of using lead aprons and thyroid collars during radiographic procedures?
✔✔ To protect the patient’s body from unnecessary radiation exposure.
1
,How do you position a patient correctly for a panoramic radiograph?
✔✔ Ensure the patient stands straight, bites into the film holder, and remains still while the
machine rotates around their head.
What is the significance of the alveolar crest in dental radiography?
✔✔ It represents the bone ridge that supports the teeth, and its height can indicate bone loss or
other conditions.
What does "radiographic density" refer to?
✔✔ The degree to which a radiograph appears dark or light, which depends on the amount of
radiation absorbed by the tissues.
How do you ensure proper film placement during a dental radiograph?
✔✔ Position the film or sensor correctly in the patient’s mouth according to the type of
radiograph being taken, ensuring it is parallel to the teeth and properly aligned.
What is the role of a dental hygienist in interpreting radiographs?
✔✔ To identify and report any abnormalities or areas of concern that may require further
evaluation or treatment by a dentist.
2
,How do you adjust exposure settings for different types of dental radiographs?
✔✔ Modify settings such as exposure time, kilovoltage (kV), and milliamperage (mA) based on
the area being examined and the type of radiograph required.
What is the purpose of a periapical radiograph?
✔✔ To provide detailed images of individual teeth and the surrounding bone structure, often
used to detect root issues or abscesses.
How do you recognize carious lesions on a radiograph?
✔✔ Carious lesions appear as darker areas on the radiograph where the tooth structure has been
demineralized.
What is the function of the collimator in a radiographic unit?
✔✔ To limit the size and shape of the X-ray beam to reduce patient exposure and improve image
quality.
How can you differentiate between a healthy tooth and one with periodontal disease on a
radiograph?
3
, ✔✔ Periodontal disease is indicated by bone loss around the tooth roots and a change in the
alveolar bone levels compared to healthy teeth.
What is the role of the radiographic developer in film processing?
✔✔ To chemically process the exposed film and produce a visible image by developing the
latent image.
How do you interpret the presence of a radiopaque structure in a dental X-ray?
✔✔ Radiopaque structures, such as enamel or metal restorations, appear lighter on the
radiograph because they block X-rays more effectively.
What precautions should be taken when using digital radiography?
✔✔ Ensure proper calibration of the digital sensor, use protective barriers, and follow protocols
to minimize radiation exposure.
What is the significance of the "film fog" in radiographic imaging?
✔✔ Film fog refers to unwanted darkening of the radiographic film caused by exposure to light
or improper processing, which can obscure diagnostic details.
