DASA RADIOGRAPHY EXAM WITH
COMPLETE SOLUTIONS
Dental Radiograph -ANSrepresentation of a three dimensional object used in dentistry
to study and identify structures not visible to the naked eye
Radiography -ANSapplying the basic sciences of physics and chemistry
Wilhelm Conrad Roentgen -ANSGerman physicist, discovered xrays in 1895
William Coolidge -ANSinvented the first xray tube in 1913
x-rays -ANSelectromagnetic rays that are not detected by any of the senses
density -ANSthe density of the object being penetrated
x-ray tube -ANSthe tube responsible for generating x-rays
Types of x-ray radiation -ANSprimary radiation, remnant radiation, secondary radiation,
scattered radiation, stray radiation
Intraoral techniques for film exposures -ANSbisecting and paralleling
Bisecting technique -ANSused to capture specific or unique radiographs
Paralleling technique -ANSmost commonly used technique for exposing the periapical
and bitewing radiographs
types of film exposures -ANSperiapical, bitewing, pano, and FMX
common radiographic errors -ANSdistortion, elongation, foreshortening, overlapping,
cone cutting, clear film, double exposure, blurred image, underexposed film,
overexposed image, radiopaque film images, and backward film
film packet -ANSouter package, dental film, black paper, and lead foil
the radiographic image -ANSdepicted by varying shades of gray, black, and white areas
radiolucent -ANSdark areas on the radiograph
radiopaque -ANSlight areas on the radiograph
