Worksheet time: 13mins
In digital radiography what replaces the intraoral film?
The sensor
The developer
The fixer
The lead apron
What are the two fundamental techniques for intraoral digital radiography?
Direct digital imaging and indirect digital imaging
Panoramic and cephalometric imaging
Analog and film-based imaging
Computed tomography and MRI
Which of the digital techniques requires scanning of image receptors?
In phosphor storage imaging (indirect digital imaging), a scanner is required to "read" the information stored on the phosphor storage plate.
Direct digital imaging, where sensors are connected directly to the computer
Digital subtraction radiography, which uses software algorithms only
Cone beam computed tomography (CBCT), which reconstructs images from raw data without scanning plates
How does the use of film holders protect the patient from unnecessary radiation?
Keeps the patient's hands and fingers from being exposed to x-radiation
Reduces the exposure time required for the procedure
Increases the sharpness of the radiographic image
Allows for faster processing of the film
What is the primary difference between a film holder and a digital sensor holder?
The size and shape of the holder
The type of lens used
The color of the holder
The brand of the camera
What is the purpose of a beam alignment?
Assist in the positioning of the position indicator device in relation to the tooth and film
Increase the exposure time for better image quality
Reduce the size of the X-ray beam for sharper images
Change the color of the X-ray beam for better contrast
What are the five components of intraoral film?
A film base made of clear cellulose acetate A thin adhesive layer that attaches the emulsion to the film base A gelatin that suspends the emulsion of microscopic silver crystals over the film base Silver halide crystals that absorb radiation A thin transparent coating that protects the emulsion
A film base made of colored plastic A thick adhesive layer that attaches the emulsion to the film base A gelatin that suspends the emulsion of gold crystals over the film base Silver nitrate crystals that absorb radiation A thick opaque coating that protects the emulsion
A film base made of clear cellulose acetate A thin adhesive layer that attaches the emulsion to the film base A gelatin that suspends the emulsion of copper crystals over the film base Silver halide crystals that reflect radiation A thin transparent coating that protects the emulsion
A film base made of clear cellulose acetate A thin adhesive layer that attaches the emulsion to the film base A gelatin that suspends the emulsion of microscopic silver crystals over the film base Silver halide crystals that absorb light A thin transparent coating that protects the emulsion
What is a latent image?
The image on the film before processing
A digital image stored on a computer
An image visible to the naked eye immediately after exposure
A photograph developed using infrared light
How can you tell which side of the film is placed toward the tube?
The white side of the film is placed toward the tube
The black side of the film is placed toward the tube
The shiny side of the film is placed toward the tube
The rough side of the film is placed toward the tube
What number film is used for adult radiographs?
Size #2
Size #0
Size #1
Size #4
What size film is used for occlusal radiographs?
Size #4
Size #0
Size #2
Size #1
What are the two types of extra oral film cassettes?
Either rigid or flexible
Either digital or analog
Either large or small
Either single or double-sided
What is an intensifying screen?
Converts radiographic energy into visible light
Measures the intensity of X-rays
Absorbs all X-ray photons
Produces electrical signals from X-rays
How does extraoral film react differently from intraoral film?
The light from the screen exposes the extraoral film, the intraoral film is exposed directly by radiation
Extraoral film is exposed only by sunlight, intraoral film is exposed by X-rays
Extraoral film does not require any exposure, intraoral film requires chemical exposure
Extraoral film is exposed by heat, intraoral film is exposed by cold
When might it be necessary to duplicate x-rays?
For the insurance company or for referral of patients to a specialist or another dental office
To decorate the dental office
To increase radiation exposure for fun
To use as bookmarks in dental textbooks
What precautions should be taken when storing x-Ray film?
Radiographic film should be stored away from light, heat, moisture, chemicals, and scatter radiation
Radiographic film should be stored in direct sunlight for better image quality
Radiographic film should be kept near heating devices to prevent moisture
Radiographic film should be exposed to chemicals to enhance sensitivity
How can you find the expiration date of a package?
The expiration date of a package of radiographic film is on the outside of the box
It is only available from the manufacturer’s website
It is printed inside the package after opening
It is determined by the date of purchase
What are the five steps in processing dental radiographs?
developing 2. rinsing 3. fixing 4. washing 5. drying

Which is the most widely used form of processing solution?
The liquid concentrate
The powder form
The solid block
The gel type
How often should be processing solutions be replenished?
Processing solutions should be replenished daily
Processing solutions should be replenished weekly
Processing solutions should be replenished monthly
Processing solutions should be replenished yearly
What is a safelight?
A low intensity light composed of long wavelength in the red orange spectrum
A high intensity blue light used in dental procedures
A device that measures radiation exposure
A type of film used in X-ray imaging
What is the minimum distance between the safelight and the working area?
4 feet
2 feet
6 feet
10 feet
What is the optimum temperature for the water in the manual processing tanks?
68 degrees F
50 degrees F
80 degrees F
100 degrees F
What is the major advantage of automatic film processing?
Less time required for processing is the major advantage of automatic film processing
It increases the size of the film
It reduces the image quality
It requires manual intervention
How often should the levels of solution in the automatic processor be checked?
Checked daily
Checked weekly
Checked monthly
Checked yearly
Are manual processing solutions and automatic processing solutions interchangeable?
Manual processing solutions and automatic processing solutions are not interchangeable.
Manual processing solutions and automatic processing solutions are always interchangeable.
Manual processing solutions are only interchangeable with semi-automatic solutions.
Automatic processing solutions can replace manual solutions in all cases.
