Dental radiation safety

  • How can we practice radiation safety?

    Patients should wear protective gowns in areas not being imaged, whether in plain radiographs, fluoroscopy, or CT scans.
    Leaded eyeglasses and should be at least 0.25 mm lead equivalents to provide adequate protection for the lens of the eye..

  • How do you ensure radiation safety?

    When it comes to ionizing radiation, remember time, distance, and shielding: Minimize time spent in areas with elevated radiation levels.
    Minimizing the exposure time reduces a worker's dose from the radiation source.
    Maximize distance from source(s) of radiation..

  • How much radiation is in a dental scan?

    A single dental x-ray, the type used to capture a single tooth, generates about a days' worth of exposure.
    A two-dimensional panoramic image of your head and jaw produces a dose comparable to 2 or 3 days of natural exposure.
    A chest x-ray on plain film will produce about 10 days of radiation..

  • What are the risks of radiation in dentistry?

    These concerns are especially strong for parents taking their children to the dentist.
    X-rays are a type of ionizing radiation, and ionizing radiation has been shown to cause cancer.
    Ionizing radiation, upon passing through the body, strip electrons from the atoms this energy passes..

  • What are the safety protection for radiation?

    Time, Distance and Shielding
    Distance: Just as the heat from a fire reduces as you move further away, the dose of radiation decreases dramatically as you increase your distance from the source.
    Shielding: Barriers of lead, concrete, or water provide protection from penetrating gamma rays..

  • What is radiation safety?

    Radiation protection aims to reduce unnecessary radiation exposure with a goal to minimize the harmful effects of ionizing radiation. [2] In the medical field, ionizing radiation has become an inescapable tool used for the diagnosis and treatment of a variety of medical conditions..

  • Personnel must:

    Avoid the primary X-ray beam.Wear protective equipment (e.g., lead aprons and thyroid collar, leaded goggles, leaded gloves).Use shielding (e.g., mobile shields, lead curtains), when possible.Be aware of the position of the beam.Know how to position themselves and the machine for the minimum dose.
  • Introduction.
    Radiographs are an indispensable diagnostic aid in dentistry as they allow the detection of disease and other abnormalities, as well as disease progression to be monitored.
    However, exposure to ionizing radiation also carries the risk of harm.
  • Rectangular collimation is strongly recommended, it approximates the size and shape of the receptor reduces dose significantly in comparison to circular collimation; a dose reduction exceeding 60 % can be achieved in dental radiology by using rectangular collimation.
Introduction. Radiographs are an indispensable diagnostic aid in dentistry as they allow the detection of disease and other abnormalities, 
Place a protective apron and/or a thyroid collar on the patient. Use rectangular collimation to reduce radiation to the patient. Stand behind a shield or at least six feet from the X-‐ray source, and out of the path of the primary beam. Give warning before pressing exposure button to protect co-‐workers and patients.
The goal of dental radiation safety and protection is to obtain diagnostic dental images while keeping exposure to a minimum. ALARA (As Low As Reasonably Achievable) is the key. Essentially, ALARA involves using safety and protection practices when taking dental images.

Are radiographs safe in dentistry?

Safe Use of Radiographs in Dentistry Radiography is an essential tool in dental practice, but recent reports of possible overutilization and overdose of radiation in some areas of health care have raised concerns among patients and practitioners about the use of radiographs in dentistry

What is the Radiation Protection Guide for dental practice?

This Report provides radiation protection guidance for the use of x rays in dental practice, including the use of cone-beam computed tomography, digital-imaging devices, and handheld x-ray systems

The aim of this Report is to provide a practical radiation protection guide for dentists and their assistants

The ADA encourages dentists to:

  • Be aware of their state’s laws and regulations which set specific requirements for the use of ionizing radiation (which includes X-rays).
  • Minimize radiation exposure by using the appropriate protective shield.
  • Use the fastest image receptor compatible with the diagnostic task (F-speed film or digital).
