Intraoral component parts include: |
>Tubehead >Extension arm >Control panel >Exposure button and indicator light |
|
|
What do beam alignment devices do? |
Help position the PID |
|
|
Intraoral film packaging contains what four parts? |
>X-ray film >Paper film wrapper >Lead foil sheet >Outer vinyl wrapper
|
|
|
What is the purpose of the paper film wrapper within the film packet? |
Covers film and protects from light. |
|
|
What is the purpose of the lead foil sheet within the film packet? |
Protects from scatter radiation |
|
|
What are three types of intraoral imaging? |
> Bite-Wing > Periapical > Occlusal |
|
|
Which imaging technique is used to examine ONLY the crowns of both maxillary and mandibular teeth in one view? |
Bite-wings |
|
|
Which imaging technique is used to examine the entire length of the tooth – both the crown and the root - in either the maxillary or mandibular arch? |
Periapical |
|
|
Which imaging technique examines broad areas of the maxilla or mandible, exposed at right angles perpendicular to the occlusal plane? |
Occlusal |
|
|
This film is intended to show the area around the root of the tooth. The entire tooth can be seen allowing the identification of root problems, interproximal caries, and the condition of the bone surrounding the teeth. |
Periapical film |
|
|
One should be able to view at least ________ above the apex of the root, when taking a ________ film. |
2-3mm ; periapical |
|
|
The entire tooth can be seen allowing the identification of root problems, interproximal caries, and the condition of the bone surrounding the teeth in what type of film? |
Periapical |
|
|
Which view uses larger film to examine large sections of the mandible and maxilla in one view? |
Occlusal view |
|
|
A full mouth series includes... |
Horizontal BW Vertical BW Periapicals |
|
|
The dental x-ray film serves as a recording medium or ________. |
Image receptor |
|
|
The basic components of x-ray film used is dentistry are... |
▪︎film base ▪︎adhesive layer ▪︎film emulsion ▪︎protective layer
|
|
|
The film emulsion gives the film ________ to x-radiation. |
greater sensitivity |
|
|
The film base emphasizes _________ and enhances ___________. |
contrast ; image quality |
|
|
The three types of film used in dental radiography are |
intraoral, extraoral, & duplicating film. |
|
|
What attracts silver atoms? |
Sensitivity specks (irregularities in the lattice structure of exposed crystals) |
|
|
The crystals with aggregates of silver at the latent image centers become |
the latent images on the film. |
|
|
What absorbs x- radiation during x-ray exposure, and stores the energy from the radiation? |
Silver halide crystals |
|
|
______ is dense and absorbs the x-ray energy. It prevents the silver halide crystals from receiving almost any radiation when they are positioned behind this restoration. |
Amalgam |
|
|
__ speed is available 130 films to a box. |
F |
|
|
__ speed is available 150 films to a box. |
D |
|
|
Is intraoral film a single or double emulsion film? Why? |
Double-emulsion, because it requires less radiation exposure to produce an image. |
|
|
What is the identification dot? |
A small raised dot used to determine film orientation. |
|
|
What is film speed? |
The amount of radiation required to produce a radiographic of standard density. |
|
|
Film speed is determined by |
The size of halide crystals, thickness of the emulsion, and presence of radiosensitive dyes. |
|
|
_______ film creates less sharp images; whereas _______ film creates images that are more sharp. |
Faster; slower |
|
|
What are the two types of film used in extraoral radiography? |
Screen film and nonscreen film. |
