Study Notes
Radiation and Imaging in Dentistry
- Energy carried by waves or particles is categorized as radiation.
- Dental images are vital for diagnosing conditions, planning treatments, and monitoring progress in patient care.
- The study of radiation in medicine is referred to as radiology.
Historical Contributions
- Wilhelm Conrad Roentgen is credited with the discovery of x-rays.
- The first dental radiograph in the U.S. was created by Dr. Edmund Kells.
- Roentgen referred to his discovery as x-radiation.
Advancements in Dental Radiography
- Dr. Kells is acknowledged for the first practical use of radiographs in dentistry.
- Common extraoral imaging techniques in dentistry include panoramic radiographs and cephalometric projections.
- An extraoral x-ray machine consists of components such as a tube head, film holder, and a source of radiation.
Intraoral Imaging Essentials
- A receptor holder is used to stabilize the x-ray film or sensor during image capture.
- A beam alignment device ensures the x-ray beam is directed accurately toward the receptor to minimize distortion.
- The first prewrapped intraoral films were manufactured by Eastman Kodak Company in 1913.
- The first machine-made periapical film packets became available in the 1920s.
Techniques and Innovations
- F. Gordon Fitzgerald revived the technique of bitewing radiography in 1947.
- The control panel of typical intraoral dental x-ray machines includes settings for exposure time, milliamperage, and kilovoltage.
Technical Aspects of X-ray Machines
- A penetrating beam of energy that records image shadows is called x-radiation.
- The recording medium used in dental radiography is often film or digital sensors.
- Dexis introduced the first intraoral imaging sensor in 1987.
Device Functions and Regulations
- The position-indicating device (PID) in x-ray machines helps to direct the x-ray beam at the receptor.
- Dental x-ray machines manufactured after 1974 must adhere to specific safety regulations.
- The timer in intraoral dental x-ray machines controls the duration of the x-ray exposure.
Additional Imaging Considerations
- A bite-block aids in holding the receptor in place during intraoral x-rays.
- Various types of receptor holders include film holders and sensor holders which assist in proper positioning.
- A collimating device is used to restrict the size of the x-ray beam, enhancing patient safety and image quality.
