Study Notes
Intraoral X-ray Film Packets
- The lead foil in intraoral X-ray film packets serves as a barrier to prevent backscatter radiation from reaching the film, reducing fog and improving image quality.
Components of Intraoral X-ray Film Packets
- A component that is NOT part of intraoral X-ray film packets is the developer.
Film Emulsion
- The gelatin in the film emulsion acts as a binder, holding the silver halides together and providing a smooth surface for image formation.
Types of X-ray Films
- Non-screen X-ray films directly capture the X-ray image, whereas screen X-ray films use intensifying screens to amplify the X-ray energy, enhancing image quality.
Radiation Protection
- The lead apron worn by patients during X-ray procedures shields their sensitive organs from scattered radiation, minimizing exposure and potential health risks.
