copy deck
- Duplication
- reproducing a radiograph for the purpose of sending the film to the insurance company or another office
- Processing error
- mistakes that occur due to improper handling of the film in the darkroom
- Proton
- subatomic particle found in the nucleus of an atom which has a postive charge
- Cone cut
- failure to center the film within the PID
- Transformer
- a device used to increase or decrease the voltage in a circuit
- Latent image
- a pattern of energized crystals that is created by the different amounts of radiation passing through structures of different densities
- Contrast
- the ability of the film to demostrate varying degrees of radiation absorption by structures of different densities
- Anatomic landmark
- assist in identifying the radiograpic view and correctly placing the radiographs in the mount
- Voltage
- the electrical force that pushes the electricity through the circuit
- Clinical examination
- the manual and visual assessment of the patient's head, neck, and oral cavity
- Developing solution
- contains chemicals that cause the silver in the energized crystals to precipitate out of the crystals while the halides are released as gas
- Adjacent
- next to or near
- Scale of contrast
- the varying shades of gray in the images of dental structures
- Wet reading
- viewing films that have been fixed 3 minutes
- Superimposition
- the proximal surface of adjacent teeth appear to overlap due to improper horizontal angulation
- Photon
- a bundle of energy
- Edentulous
- the absence of natural teeth
- Full mouth survey
- a series of radiographs exposed in all teeth bearing areas of the mouth
- Fixing solution
- contains chemicals that remove the undeveloped silver halide crystals and harden the emulsion
- Vertical angulation
- controls the length of the image
- Pedodontic
- a survey of radiographic examination of the primary dentition
- Tube film distance
- describes the distance between the targe and film
- Periapical radiograph
- contain images of the entire tooth from the crown to 3-4mm beyond the apex
- Radiograph
- a special type of photographic image produced by the use of x-rays and x-ray film
- Long axis
- an imaginary vertical line from the apex to the incisal or occlusal edge of a tooth
- Nucleus
- the center core of an atom
- Mount
- a plastic or cardboard holder to facilitate viewing and interpretation of radiographic surveys
