Oral Radiography

Module I - Intro to Oral Radiography

TermDefinition
Radiation A form of energy carried by waves or a stream of particles
X-ray A beam of energy that has the power to penetrate substances and record image shadows on photographic film or digital sensors
Radiograph A two-dimensional representation of a three-dimensional object
Radiography The art and science of making radiographs by the exposure of film to x-rays
Image A picture or likeness of an object
Dental Imaging the process of producing an image of teeth and related structures by radiographic techniques
X-radiation A high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube
Radiology The study of radiation as used in medicine; a branch of medical science that deals with the use of x-rays, radioactive substances, and other forms of radiant energy in the diagnosis and treatment of disease
Dental radiograph Two-dimensional representation of a three-dimensional object produced on an image receptor by the passage of x-rays through teeth and related supporting structures
Dental radiography The production of radiographs of teeth and adjacent structures by the exposure of an image receptor to x-rays
Image receptor a recording medium; examples include x-ray film or digital sensors
Uses of dental radiographs Detect lesions, disease and conditions Confirm or classify suspected diseases Localize lesions or foreign objects Provide information during dental procedures Evaluate growth and development
Uses of dental radiographs continued Illustrate changes secondary to caries, periodontal disease, and trauma Document the condition of a patient at a specific point in time Aid in clinical treatment plan Used as a diagnostic tool during assessment procedures
Uses of dental radiographs continued A necessary component of comprehensive patient care Import aid in patient education Used to detect oral disease Used to detect condition of teeth that cannot be seen clinically Provide a permanent record of the patient's oral condition
Uses of dental radiographs continued Used for legal evidence Used for forensic purposes
Dental X-ray Machine Operator Any member of the dental team who positions, exposes, and processes a dental x-ray receptor (x-ray film or digital sensor)
Wilhelm Conrad Rontgen German physicist Produced and detected electromagnetic radiation (x-rays) Nobel Prize in Physics in 1901 Father of Diagnostic Radiology First radiograph was taken of his wife's hand and ring
Dr. Otto Walkoff Developed first dental radiographs in 1896 He was both the patient and the dentist Exposure time was 25 minutes Diagnostic quality left a great deal to be desired
Dr. Edmund Kells First practical use of radiographs in dentistry in 1896 Lost an arm due to overexposure while experimenting with xrays
First dental radiographs made in the United States Made in 1896 with the use of Eastman NC roll film wrapped in black paper
William Rollins Developed the first dental x-ray unit in 1896 Reported burns to his hands because he held the film in the patient's mouth during exposure and recommended lead shielding of both the x-ray tube and the patient and worker
William David Coolidge Invented the x-ray tube (Coolidge tube) First high-vacuum x-ray tube with a heated cathode as the source of electrons Significantly increased radiation intensity Allowed reliable control and fine adjustment
