For most adults, dental x-rays are typically recommended once every 24 to 36 months for routine check-ups. However, in certain cases, such as for patients with a history of dental problems or those undergoing orthodontic treatment, more frequent x-rays may be necessary..
How many dental x-rays are safe per year?
A general dentist will recommend that x-rays are taken once per year. For most patients, two routine checkups per year are recommended..
How much radiation are you exposed to with dental x-rays?
On average, your body is exposed to 3.1 millisieverts (mSv) of natural radiation alone per year. At . 005 mSv, the radiation you receive from the aforementioned dental x-ray is less than 1.6% of your daily background radiation exposure. You are exposed to the same level of radiation just from sunlight each day..

What are the exposure limits for dental x-rays?
1 FMX (90 μSv) \x26lt; background radiation dose per year (3600 μSv). 10,000 dental x-rays = maximum permissible dose per person per year (50,000 μSv). 1 dental x-ray \x26lt; 1 medical radiographic procedure..
Ask your dentist if he/she uses the faster (E or F) speed film for X-rays. It costs about the same as the conventional D speed film and offers similar benefits with a lower radiation dose. Using digital imaging detectors instead of film further reduces radiation dose.
There is no number that is definitely safe, just as there is no number that is definitely dangerous. Every x-ray can involve some tiny risk. If the x-ray is needed to find out about a medical problem, then that small risk is certainly worth taking.
When X-ray radiation is absorbed within our bodies, it can damage molecular structures and potentially cause harm. Very high doses of radiation cause damage to human cells, as evidenced by skin burns, loss of hair, and increased incidence of cancer.
Are Dental X-rays Safe? Patients are exposed to extremely minimal radiation doses during dental x-ray procedures. A patient who undergoes a bitewing x-ray procedure will receive a radiation dose of 0.4 mrem, while a panoramic x-ray radiation dose exposure is approximately 0.7 mrem.

Are dental X-rays the most common source of ionizing radiation exposure?
Purpose:
Routine dental X-rays are among the most common sources of ionizing radiation exposure for healthy individuals globally, with 300 examinations/1000 individuals/year as documented by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) global survey of medical radiation usage and exposure
Do dental X-ray exposures have biological effects?
A comprehensive review of the literature on the biological effects from dental X-ray exposures In general, the total number of studies is low and the majority of the data has been generated from poorly designed experiments
Dental x ray exposure
Measure of ionization of air by ionizing radiation
Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. As of 2007, medical radiation exposure was defined by the International Commission on Radiological Protection as exposure incurred by people as part of their own medical or dental diagnosis or treatment; by persons, other than those occupationally exposed, knowingly, while voluntarily helping in the support and comfort of patients; and by volunteers in a programme of biomedical research involving their exposure. Common medical tests and treatments involving radiation include X-rays, CT scans, mammography, lung ventilation and perfusion scans, bone scans, cardiac perfusion scan, angiography, radiation therapy, and more. Each type of test carries its own amount of radiation exposure. There are two general categories of adverse health effects caused by radiation exposure: deterministic effects and stochastic effects. Deterministic effects are due to the killing/malfunction of cells following high doses; and stochastic effects involve either cancer development in exposed individuals caused by mutation of somatic cells, or heritable disease in their offspring from mutation of reproductive (germ) cells.
