    • Adds more scatter radiation and exposure

    • Minimizes Radiation exposure but increases scatter

    • Adds Scatter radiation

    Correct Answer
    A. Minimizes amount of radiation exposure
    Explanation
    The correct answer is "Minimizes amount of radiation exposure." This means that the Position Indicating Device (PID) helps to reduce the level of radiation exposure. It does not add scatter radiation or increase exposure. Instead, it works to minimize the amount of radiation that the individual is exposed to, which is beneficial for their safety and health.

    The Film Developer is a Portable Light safe box with Developer, Fixer and Water in small containers

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because a film developer is indeed a portable light-safe box that contains small containers of developer, fixer, and water. This setup allows photographers to develop their film in a controlled environment without exposing it to light. The developer is used to convert the latent image on the film into a visible image, the fixer is used to remove any unexposed or undeveloped silver halides, and water is used for rinsing the film after development.

    While using the bisecting angle technique, you lay the film far enough inside the animals mouth, so the root structure will be projected on the film.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The bisecting angle technique is a dental radiographic technique used to capture dental images. In this technique, the film is placed inside the animal's mouth in such a way that it extends far enough to capture the root structure of the teeth. By angling the x-ray beam, the root structure is projected onto the film, allowing for a clear and accurate dental image. Therefore, the statement that while using the bisecting angle technique, the film is laid far enough inside the animal's mouth to project the root structure on the film is true.

    Rate this question:

  • 5. 

    Would you recommend taking a Digital Extra for a Tooth that was Discoloured?

    • Yes

    • No

    Correct Answer
    A. Yes
    Explanation
    Taking a digital extra for a discolored tooth is recommended because it allows for a more accurate assessment of the tooth's condition. A digital extra involves taking a high-resolution image of the tooth, which can help identify any underlying issues that may be causing the discoloration. This information is crucial in determining the appropriate treatment plan for the tooth, whether it be a simple cosmetic procedure or a more extensive dental intervention. Therefore, opting for a digital extra can aid in making an informed decision regarding the best course of action for the discolored tooth.

    Rate this question:

  • 6. 

    The object being radiographed should be

    • As close to the film as possible

    • As close to the beam as possible

    • As far away to the film as possible

    • As far away to the beam as possible

    Correct Answer
    A. As close to the film as possible
    Explanation
    The object being radiographed should be as close to the film as possible in order to obtain a clear and accurate image. This is because the distance between the object and the film affects the sharpness and resolution of the radiograph. By placing the object close to the film, the X-ray beam has a shorter distance to travel, reducing the risk of blurring or distortion in the image. Additionally, a shorter distance helps to minimize the scatter radiation that can interfere with the clarity of the radiograph.

    What is a PID

    • Pocket Imaging Device

    • Minimizes amount of radiation exposure, and is lead lined.

    • Separate device from the Machine

    • The Short Version uses 1/2 the exposure and is hard to position

    Correct Answer
    A. Minimizes amount of radiation exposure, and is lead lined.
    Explanation
    A PID (Pocket Imaging Device) is a device that is designed to minimize the amount of radiation exposure during imaging procedures. It is lead lined to provide additional protection from radiation. The PID is a separate device from the machine, and it is used to position the patient properly for imaging. The short version of the PID uses half the exposure but may be more difficult to position accurately.

    Radiographs can determine multiple things when referring to Dental. Pick the ones specific for Dental.

    • Impaction/Unerupted

    • Extent of periodontal Disease

    • Bone Loss

    • Root Abscesses/Status

    • Lameness

    Correct Answer(s)
    A. Impaction/Unerupted
    A. Extent of periodontal Disease
    A. Bone Loss
    A. Root Abscesses/Status
    Explanation
    Radiographs are commonly used in dental examinations to assess various aspects of dental health. They can help determine if there are any impacted or unerupted teeth, which refers to teeth that are unable to properly emerge from the gum line. Radiographs can also reveal the extent of periodontal disease, which is a condition that affects the gums and supporting structures of the teeth. Additionally, they can detect bone loss, which is often associated with advanced periodontal disease. Furthermore, radiographs can identify any root abscesses or assess the status of existing abscesses. However, radiographs are not typically used to assess lameness, as this symptom is more related to musculoskeletal issues rather than dental problems.

  • 11. 

    The Dental Film is placed in the fixing solution for

    • 30 seconds

    • 20 seconds

    • 1 minute

    • 40 seconds

    Correct Answer
    A. 30 seconds
    Explanation
    The Dental Film is placed in the fixing solution for 30 seconds in order to complete the fixing process. Fixing is a step in the development of dental films where the unexposed silver halide crystals are removed from the film emulsion. This helps to stabilize the image and prevent further darkening of the film. The fixing solution contains chemicals that dissolve the unexposed silver halide crystals, leaving behind only the developed silver grains that form the image. 30 seconds is the optimal time required for the fixing solution to effectively remove the unexposed silver halide crystals without causing any damage to the developed image.

  • 12. 

    If you aim the PID at the tooth instead of the bisecting angle, what would happen?

    • Elongation

    • Foreshortening

    • Superimposition

    • Artifacts

    Correct Answer
    A. Elongation
    Explanation
    If the PID (position indicating device) is aimed at the tooth instead of the bisecting angle, it would result in elongation. Elongation occurs when the object being radiographed appears longer than it actually is due to improper angulation of the X-ray beam. In this case, aiming the PID at the tooth would cause the X-ray beam to be directed towards the tooth, resulting in an elongated image of the tooth on the radiograph.

    Rate this question:

  • 15. 

    The Dental film is in the Developing Solution for ?

    • 10-30 seconds

    • 1-3 minutes

    • 30-60 seconds

    • 3-6 minutes

    Correct Answer
    A. 10-30 seconds
    Explanation
    The dental film is placed in the developing solution for 10-30 seconds. This is the optimal time required for the film to develop properly and produce clear and accurate images. If the film is left in the solution for too long, it may become overdeveloped and result in darker images with less detail. On the other hand, if the film is not left in the solution for long enough, it may be underdeveloped and produce lighter images with less contrast. Therefore, the recommended time of 10-30 seconds ensures the best results for dental imaging.

    Correct Answer
    Position Indicating Device
    PID
    Explanation
    The oral radiographic equipment includes a control panel with a timer and exposure settings, a long arm extending from the control panel, and a tube head. The tube head is equipped with a Position Indicating Device (PID). The PID is used to accurately position and direct the X-ray beam towards the desired area of the patient's mouth. It helps in ensuring that the X-rays are targeted correctly and reduces the risk of unnecessary exposure to radiation.

    Rate this question:

  • 17. 

    You should include the ____ and supporting bone in your radiograph

    Correct Answer
    Root
    Explanation
    In order to obtain a comprehensive radiograph, it is crucial to include the root and supporting bone. This is because the root provides important information about the tooth's structure and health, while the supporting bone helps to assess the stability and condition of the tooth. By including both the root and supporting bone in the radiograph, a more accurate diagnosis can be made regarding any potential issues or abnormalities present in the tooth and surrounding structures.

    Rate this question:

  • 18. 

    If you aim the PID at the film instead of the bisecting angle, what would happen?

    • Foreshortening

    • Elongation

    • Superimposition

    • Artifacts

    Correct Answer
    A. Foreshortening
    Explanation
    If the PID (position-indicating device) is aimed at the film instead of the bisecting angle, foreshortening would occur. Foreshortening is a radiographic distortion that happens when the X-ray beam is not aligned properly with the object being imaged. This causes the object to appear shorter or compressed on the resulting radiograph. In this case, if the PID is pointed directly at the film, it would result in an incorrect alignment of the X-ray beam, leading to foreshortening of the image.
