Radiation
Energy carried by waves or particles
X-Radiation
High energy radiation produced by the collision of a beam of electrons with a metal target in an X-ray tube
X-Ray
A beam of energy that has the power to penetrate substances and record image shadows on an image reception (film, sensor, or plate)
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.
Radiograph
An image or picture produced on a receptor (digital sensor, radiation sensitive film, or phosphor plate) by exposure of one of these image receptors to ionizing radiation
A TWO DIMENSIONAL REPRESENTATION OF A THREE DIMENSIONAL OBJECT
Dental Radiograph
An image produced on a receptor by the passage of x rays through teeth and related structures
Radiography
The science of making radiographs by the exposure of film to x-rays
Dental Radiography
The production of radiographs of the teeth and adjacent structures by the exposure of film to x-rays
Dental Radiographer
Any person who positions, exposes, and processes x-ray image receptors
Image
A picture or likeness of an object
Image receptor
A recording medium; x-ray film, phosphor plate, or digital sensor
Dental imaging
The creation of digital, print, or film representations of anatomic structures for the purpose of diagnosis
Uses of dental Images
Detect lesions
Confirm or classify suspected disease
Localize lesions or foreign objects
Provide information during dental procedures
Evaluate growth. and development
Illustrate changes secondary to caries, periodontal disease, or trauma
Document the condition of a patient
Aid in development of a clinical treatment plan
Wilhelm Conrad Roentgen
Discovered x-ray in 1895
Otto Walkhoff
Made the first dental radiograph in 1895
C. Edmund Kells
Exposed the first dental radiograph in the U.S. on a patient in 1896
Howard Riley Raper
First dental textbook pertaining to radiology in 1913
William Coolidge
Developed the first hot-cathode X-ray tube with a tungsten filament that became a prototype for all modern-ray tubes
Eastman Kodak
Manufactures rewrapped intraoral film in 1913
First intramural imaging sensor was introduced in
1987
Cone-beam computed tomography (CT scan) was introduced in
This allows viewing structures in 3-D
1999
Component Parts of the Intraoral Dental X-Ray Machine
Tubehead
PID (Position indicating device) extends from tube head
Extension Arm
Control Panel
Receptor Holder
Device used to hold and align intraoral x-ray receptors (digital sensor or film)
- single use disposable styrofoam bit block
- EndoRay used to take an x-ray during root canal
-Reusable remolded plastic devices
Snap a Ray
Bean alignment device
An instrument used to position the PID correctly
- Rinn XCP and BAI instruments
Collimating Device
Retrofitted onto the end of the PID and restricts the size of the x-ray beam and reduce the area of tissue exposed to radiation
Information found on dental images
Missing teeth Extra teeth Impacted teeth Dental caries Periodontal disease Tooth abnormalities Retained roots Cysts and tumors
