Question 1

Which of the following statements is true of the film holder?&#10;A) It is used to align an extraoral dental x-ray film.&#10;B) It requires the patient to stabilize the film in the mouth.&#10;C) It is required when using the intraoral paralleling technique.&#10;D) It is required when using the intraoral bisecting technique.

Accepted Answer

The film holder is required when using the intraoral paralleling technique, which involves placing the dental x-ray film parallel to the long axis of the tooth being radiographed. The film holder helps to stabilize the film in the correct position for accurate imaging. Option A is incorrect as extraoral films are not placed inside the mouth. Option B is incorrect as the film holder is used to stabilize the film, not the patient. Option D is incorrect as the intraoral bisecting technique does not require a film holder, but instead relies on the clinician's ability to hold the film in place with their fingers.

Question 2

The Rinn XCP system includes a:&#10;A) Beam alignment device.&#10;B) Styrofoam bite-block.&#10;C) Snap-on metal collimating device.&#10;D) Both a and c.

Accepted Answer

The Rinn XCP system includes both a beam alignment device and a snap-on metal collimating device. The styrofoam bite-block is not part of the XCP system.

Question 3

A beam alignment device can be used to help the dental radiographer position the PID in relation to the ____ and film.&#10;A) control panel&#10;B) extension arm&#10;C) collimator&#10;D) tooth

Accepted Answer

The beam alignment device helps position the PID (Position Indicating Device) in relation to the tooth and the film to ensure accurate and consistent radiographic images.

Question 4

Which of the following are beam alignment devices?&#10;A) Stabe bite-block&#10;B) XCP bite-block&#10;C) EEZEE-Grip&#10;D) Precision film holders

Accepted Answer

The answer of Which of the following are beam alignment...

Question 5

The ____ activate(s) the machine to produce x-rays.&#10;A) on-off switch&#10;B) exposure button&#10;C) exposure light&#10;D) control devices

Accepted Answer

The exposure button is the control device that activates the machine to produce x-rays. The on-off switch only turns the machine on and off, the exposure light indicates when an x-ray is being taken, and control devices refer to any device that helps to adjust and regulate the x-ray machine settings. Therefore, the best choice is B - exposure button.

Question 6

Features of the Stabe bite-block include:&#10;A) Disposable.&#10;B) Slot for film retention.&#10;C) Molded plastic that can be sterilized.&#10;D) Both a and b.

Accepted Answer

The Stable bite-block is both disposable and has a slot for film retention. It is not made of moldable plastic, but rather a rigid material that cannot be sterilized. Therefore, options A and B are both correct.

Question 7

____ regulate(s) the manufacture and installation of dental x-ray equipment.&#10;A) The federal government&#10;B) State governments&#10;C) Local governments&#10;D) Municipal governments

Accepted Answer

The federal government regulates the manufacture and installation of dental x-ray equipment through the Food and Drug Administration (FDA) and the Center for Devices and Radiological Health (CDRH). State and local governments may have additional regulations or requirements for the use and maintenance of this equipment, but the federal government sets the overall standards.

Question 8

The ____ allow(s) for positioning of the tubehead.&#10;A) control devices&#10;B) extension arm&#10;C) control panel&#10;D) exposure button

Accepted Answer

The extension arm allows for positioning of the tubehead. The control devices, control panel, and exposure button do not directly facilitate positioning of the tubehead.

Question 9

Which of the following intraoral film holders is a disposable Styrofoam bite-block?&#10;A) EEZEE-Grip&#10;B) Stabe bite-block&#10;C) EndoRay&#10;D) Uni-bite

Accepted Answer

The Stabe bite-block is a disposable Styrofoam bite-block, making it the best choice out of the listed options. The EEZEE-Grip, EndoRay, and Uni-bite are all reusable film holders.

Question 10

A ____ eliminates the need for the patient to stabilize the film.&#10;A) PID (position-indicating device)&#10;B) film holder&#10;C) control panel&#10;D) beam alignment device

Accepted Answer

A film holder eliminates the need for the patient to stabilize the film by holding it in place during exposure. It securely and accurately positions the film in the mouth, reducing the risk of movement and distortion of the radiographic image. A PID, control panel, and beam alignment device may assist with other aspects of radiographic technique but do not address patient stabilization of the film.

Question 11

The position-indicating device (PID) is an extension of the:&#10;A) Tubehead&#10;B) Extension arm&#10;C) Control panel&#10;D) Exposure button

Accepted Answer

The answer of The position-indicating device (PID) is an extension...

Question 12

During an exposure:&#10;A) The exposure button is briefly depressed and then released to initiate the exposure.&#10;B) The exposure button is firmly depressed until the preset exposure time is completed.&#10;C) The exposure light on the control panel is illuminated to signal the completion of the exposure.&#10;D) A beep sounds to signal initiation of the exposure.

Accepted Answer

The answer of During an exposure:&#10;A) The exposure button is...
