Intraoral Dental X-Ray Film

Intraoral dental x-ray film is direct exposure film. It is also a double emulsion film. Double emulsion permits the use of less radiation to make a radiograph.

Categories according to clinical applications
1. Periapical film is used to record crowns, roots and periapical of teeth.
2. Bitewing film is used to record crown of maxillary and mandibular teeth in one radiograph.
3. Occlusal film is used to record large anatomy or region of maxilla, like maxillary anterior occlusal view, or mandible, like mandibular anterior occusal view.

X-ray film two principal components
1. Emulsion is sensitive to x-ray. It records the radiographic image.
2. Base functions as support for the emulsion.

Emulsion two principal components
A. silver halide crystals
B. gelatin matrix

Silver halide crystals components
a. silver bromide (primarily)
b. silver iodide

Film Base is composed primarily of polyethylene terephthalate.

    Is the emulsion on fast film thinner or thicker than on slower films?
    I know that fast films have emulsion on both sides of the film. Thank you

    Hi susan. Thicker emulsion or double emulsion increase film speed.

    SO what are periapical films made out of? Are they covered with a double emulsion that contains silver bromide? Or something along those lines?

    Thanks
