Study Notes

Components of Intraoral X-ray Film Packets

A component that is NOT part of an intraoral X-ray film packet is the lead foil wrapper.

Purpose of Lead Foil

The lead foil in intraoral X-ray film packets prevents backscatter radiation from reaching the film.

Film Emulsion

The purpose of the gelatin in the film emulsion is to hold the silver halides in place.

Types of X-ray Films

Non-screen X-ray films use the film emulsion to record the X-ray image, whereas screen X-ray films use phosphor screens to amplify the X-ray image.

Protective Black Paper

The protective black paper in intraoral X-ray film packets prevents light exposure from reaching the film.
