[Shielding during dental X-ray examinations. Effectiveness of radiation protection measures for patients during X-ray examinations].

During dental X-ray examinations, lead rubber shields such as neck protections or half aprons are commonly used to protect the patient against unnecessary radiation. However, they are practically of no use to the patient as it has been shown by the present measurements. The scatter radiation produced in the body of the patient creates organ doses outside of the collimated radiation field. Other radiation protection measures are more effective and should be considered, although the doses are usually low.
