Abstract

Panoramic dental radiography using an intraoral X-ray source exposes critical organs, such as the crystalline and the thyroid, as well as organs of fundamental importance such as the pituitary gland, to X-rays. An experimental study was carried out to assess the exposure dose to the sella turcica during the radiological examination of the upper and lower dental arches using an X-ray source within the oral cavity. The comprehensive exposure dose for the upper and lower dental arches exceeded that found in orthopantomography (110 micro Gy/examination vs 47 micro Gy/examination) with errors which are respectively inferior to 15% and 30%. The authors conclude that the risk of provoking anatomical or functional changes of the pituitary gland is extremely remote using this type of examination.
