Study Notes
Filtration in Dental X-ray Machines
- Added filtration in dental x-ray machines refers to the placement of aluminum disks in the path of the x-ray beam between the collimator and the tubehead seal.
Limiting X-radiation Exposure
- The first important step in limiting the amount of x-radiation received by a dental patient is to use filtration.
Types of Filtration
- There are two types of filtration used in the dental x-ray tubehead: inherent and added filtration.
Radiation Safety for Dental Radiographers
- Dental radiographers should stand at an angle of 90 degrees to the x-ray beam while taking dental images to minimize radiation exposure.
- Only dental personnel, including dental radiographers, should be monitored for radiation exposure protection.
- Radiation badges should be worn on the collar or lapel, outside of any lead apron.
Dental Radiographer Roles and Responsibilities
- MPD stands for Master of Dental Public Health.
- Both dentists and dental hygienists can serve as dental radiographers in a typical dental practice.
- Dental radiographers are responsible for taking and developing dental images, as well as maintaining the x-ray machine and ensuring patient safety.
Avoiding Occupational Exposure
- To avoid occupational exposure to x-radiation, dental radiographers should stand at a distance from the x-ray machine, use a long cone, and wear a radiation badge.
Collimators and Position-Indicating Devices
- A long, pointed collimator restricts the size of the x-ray beam to an area slightly larger than a size 2 intraoral receptor.
- A Position-Indicating Device (PID) should be at least 12 inches long to decrease patient exposure.
Patient Protection Devices
- A thyroid collar is a recommended patient protection device for all intraoral exposures to protect the thyroid gland from scatter radiation.
Dental X-ray Film
- Digital x-ray film provides the highest reduction in exposure over earlier films.
