Lecture One Material Flashcards
If photographic image produced on image receptor by the passage of x-rays through teeth and related structures
Dental radiograph
Any person who positions exposes and processes dental x-ray image receptors
Dental radiographer
The production of radiographs of the teeth and adjacent structures by the exposure of an image receptor x-rays
Dental radiography
A glow that results when I fluorescent substance is struck by light Cathode rays or x-rays
Florescence
A form of energy carried by waves or a stream of particles
Radiation
A high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube
X-radiation
A beam of energy that has the power to penetrate substances and record image of shadows on photographic film or digital sensors
X-ray
How do radiographs benefit patients?
Detect disease
Minimize and or prevent problems
Save time and money
Why do we have guidelines on whom and when we can take x-rays?
To protect the patient and operator
What are periapical films?
Films which examine the entire tooth and surrounding bone of a given area on one film. Can be taken on both dentulous and edentulous areas
What is an FMX
A full mouth series of x-ray films. Determined by what is needed by that specific patient. Always take the minimum amount of x-ray film to get the whole diagnostic picture of the patient’s mouth
Bitewing x-rays films
Show both the maxillary and Mandibular teeth and surrounding bone of one area on a film
What is an occlusal film
Called occlusal because the patient bites or occludes on the film itself. Placed on the occlusal plane of the patient’s mouth. Examines large areas of either the maxillary or mandibular
What is angulation?
The alignment of the central Ray of the x-ray beam in the horizontal and vertical Planes.
Can be varied by moving the PID in either a horizontal or vertical direction.
The positioning of the PID and direction of the rays in a side to side plane
Horizontal angulation
