Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.

An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
The best thing to lower radiation exposure is to make sure the patient needs the X-ray and to do it right the first time, said Dr. Purnima Kumar, who chairs the American Dental Association Council ...
Lead is the most common shield against X-rays because of its high density (11,340 kg/m 3), stopping power, ease of installation and low cost. The maximum range of a high-energy photon such as an X-ray in matter is infinite; at every point in the matter traversed by the photon, there is a probability of interaction.
Medical credit cards cover medical and dental expenses, and in many cases, medical providers will even offer special financing terms, like 0 percent interest, for some time.
ConeBeam computerized tomography image of a post-operative orthognathic surgery. Oral and maxillofacial radiology, also known as dental and maxillofacial radiology, or even more common DentoMaxilloFacial Radiology, is the specialty of dentistry concerned with performance and interpretation of diagnostic imaging used for examining the craniofacial, dental and adjacent structures.
Roentgen a legacy unit of measurement for the exposure of X-rays; Each measure is often simply described as ‘dose’, which can lead to confusion. Non-SI units are still used, particularly in the USA, where dose is often reported in rads and dose equivalent in rems. By definition, 1 Gy = 100 rad and 1 Sv = 100 rem.
