Question | Answer |
Underdeveloping | Results in light, difficult to view films-caused from insufficient processing with weak chemicals, time or temperature. |
Overdeveloping | results in radiographs that are too dark and difficult to interpret |
Foreshortening | Tooth structures appear shorter than their actual anatomical size-caused by excessive vertical angulation |
Elongation | the image of tooth structure appears longer tan actual size due to insufficient vertical angulation |
Overlapping | distortion of the film showing an overlapping of the crowns superimposed on adjacent teeth-caused by improper horizontal angulation |
Cone cutting | improper placement of the central beam which is caused by lack of exposure to radiation. PID is not centered properly |
Reticulation | crackling of film emulsion caused by large temperature differences between processing solutions. gives a stained glass effect. |
Fog | clouded, darkened, or blemished x-ray film results- caused by old film, contaminated solutions, faulty safelight, improper storage of film |
Herringbone effect | fish bone effect on film surgace resulting from placing film in the mouth backwards |
Landmarks | anatomic structures that act as guides |
Contrast | Variations in shades from black to white |
Density | film blackening occurring from the percentage of light transmitted through a film |
Radiolucent | portion of radiograph that appears dark or ability of a substance to permit passage of x-ray causing darkening on film |
Radiopaque | portion of radiograph that appears light or the ability of a substance to resist x-ray penetration causing light area on the film |
Definition | outline sharpness and clarity of image exhibited on radiograph |
Double exposure | two exposures on one film |
Panoramic radiograph | extraoral radiograph showing the entire mandible, maxilla, teeth and other structures |
Extraoral radiographs | radiographs taken outside of the mouth |
