Oral Radiography
Module I - Intro to Oral Radiography
| Term | Definition |
|---|---|
| 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 |
