DEN 130 1 H - Dental Radiology- 39

A set of flashcards designed to help students study key concepts related to Digital Imaging, Dental Film, and Film Processing, as outlined in their lecture notes.

What are the purposes of digital radiography in dentistry?

To capture, store, and display dental images digitally for easier viewing and sharing.

What is the difference between direct and indirect digital imaging?

Direct imaging uses solid-state sensors to capture images directly, while indirect imaging uses phosphor plates that require scanning to digitize the image.

What are phosphor storage plates?

Flexible imaging plates coated with phosphor crystals that can store x-ray energy and require scanning to produce digital images.

Why are infection control measures important in digital radiography?

Because sensors and phosphor storage plates are reused, they must be protected from contamination.

What are the five basic sizes of intraoral dental film?

Child (size 0), Narrow anterior (size 1), Adult size (size 2), Preformed bitewing (size 3), Occlusal (size 4).

Describe the composition of intraoral film.

Intraoral film is made of a clear, semi-flexible cellulose acetate base coated with silver bromide, silver halide, and silver iodide.

What is the latent image in film processing?

The image that is formed on the film after exposure to radiation but is not visible until the film is processed.

What is the film speed in dental radiography?

The amount of radiation required to produce a radiograph of standard density, determined by silver halide crystal size and emulsion thickness.

What are the common processing errors in film processing?

Overdevelopment, underdevelopment, developer splash, scratched film, fixing errors, and fogged films.

What are the steps in film processing?

Development, rinsing, fixation, washing, and drying.
