Ch. 22 KT Day 2 Cycle 3

automatic processing

processing of dental x-rays using automated equipment

bisecting technique

x-ray technique that applies the geometric principle in which the central ray bisects the angle formed by the dental film and the long axis of the tooth

bite-wing radiograph

intraoral radiograph that shows the maxillary and mandibular crowns in occlusion

blurred image

images on x-ray film that are out of focus

cone cutting

partial image created when the central beam misses the x-ray film

developer solution

the first chemical solution used to process radiographs

double exposure

a technique error in which film was exposed twice

duplication technique

a technique whereby dental radiographs are reproduced on a specialized film

elongation

a technique error that elongates the image of the teeth

fixer solution

the second chemical solution used in processing radiographs

foreshortening

a technique error whereby the image of the teeth is shortened

herringbone pattern

a cross pattern that appears on film that has been placed backward in the mouth

hortizontal angulation

adjustment of angulation from left to right; improper angulation shows overlapping teeth

interproximal

radiographs; also known as bite-wing radiographs

manual processing

processing x-rays using a manual tank with developer, running water, and fixer

occlusal radiograph

radiographs that expose the maxillary or mandibular occlusal surface of the dental arch

overlapping

x-ray technique error resulting from improper hortizontal angulation

paralleling technique

x-ray technique, also known as the right-angle technique, whereby the film and tooth and PID are parallel

periapical radiograph

x-ray showing the tooth and surrounding tissues

quality radiograph

a radiograph that shows all structures in a manner that makes assessment and diagnosis efficient and clear

radiopaque

white or light region on the x-ray indicating where radiation was blocked by tissue or a substance

reticulation

processing error that shows on the dental film when the film emulsion is exposed to extreme temperature variations

underexposed

when the x-ray film appears light and has a thin image

vertical angulation

adjustment of angulation from top to bottom; improper vertical angulation shows teeth elongated or foreshortened
