What would an extraoral film be used for?
Extraoral Film Extraoral films are used to examine large areas of the head or jaws. Examples of common extraoral films include panoramic and cephalometric films. A panoramic film shows a panoramic (wide) view of the upper and lower jaws on a single radiograph.
What is an extraoral cassette?
Extraoral cassettes complement LANEX screens for high quality images each and every time. Page 2. Extraoral Cassette with Screens. Exceptional quality and value. Extraoral cassettes provide the perfect mix of value and performance to help you capture high quality images at an affordable price.
What are the five basic sizes of intraoral dental film?
Intraoral film packets come in five basic sizes:
- Child (size 0)
- Narrow anterior (size 1)
- Adult size (size 2)
- Preformed bite-wing (size 3)
- Occlusal (size 4)
What is an extraoral radiograph?
What are Extraoral Radiographs? Like the first part of the name suggests, extraoral X-rays are made with the film outside the mouth. This type of X-ray still shows the teeth but can also provide important information about the jaw and skull.
How does extraoral film react differently from intraoral film?
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.
What is the purpose of an intensifying screen in an extraoral cassette?
The combination of screen films, intensifying screens and cassettes are used in making extraoral images. The main function of screens is to reduce radiation to the patient. Currently, there are two groups of X-ray films for dental purposes: 1.
What are the two types of extraoral film?
There are several types of extraoral X-rays.
- Panoramic X-rays show the entire mouth area — all the teeth in both the upper and lower jaws — on a single X-ray.
- Tomograms show a particular layer or “slice” of the mouth and blur out other layers.
- Cephalometric projections show an entire side of the head.
How does the film used in extraoral radiography differ from that used for intraoral radiographs?
There are two main types of dental X-rays: intraoral (the X-ray film is inside the mouth) and extraoral (the X-ray film is outside the mouth). Intraoral X-rays are the most common type of X-ray.
Which type of dental radiographic film uses the least amount of radiation?
Intraoral x-ray film; because it requires less radiation to produce an image.
What is E speed film?
The film typically used for the intraoral bitewing exam falls into three film speed classes – D (slowest), E and F-speed (fastest). Like photographic film, the faster the film, the less exposure it needs. Film speed can be an important aspect in determining the amount of radiation exposure received by a patient.
What is the main benefit of using an intensifying screen?
Intensifying screens are used in the x-ray cassette to intensify the effect of the x-ray photon by producing a larger number of light photons. It decreases the mAs required to produce a particular density and hence decreases the patient dose significantly.

What is an extraoral X-ray?
The extraoral radiography using the extraoral films finds its use in imaging the skull, temporomandibular joint along with the jaw bones.

The x-rays help to image the internal structures on the film and allowing the dentist to see the hidden issues.
What is the difference between G-screen and extraoral film?
The screen films are sensitive to the fluorescent light rather than the direct x-rays. The extraoral films are used in combination with the cassettes and the intensifying screens. g screen and the extraoral film, is available in various sizes that correspond the screen and the film sizes.
What is the size of extraoral film?
