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.
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.
This is the method used in the original discovery of X-ray diffraction. Laue scattering provides much structural information with only a short exposure to the X-ray beam, and is therefore used in structural studies of very rapid events (time resolved crystallography). However, it is not as well-suited as monochromatic scattering for determining ...
X-ray diffraction computed tomography is an experimental technique that combines X-ray diffraction with the computed tomography data acquisition approach. X-ray diffraction (XRD) computed tomography (CT) was first introduced in 1987 by Harding et al. [ 1 ] using a laboratory diffractometer and a monochromatic X-ray pencil beam .
Niobium - Used in radiography and dental radiography with tungsten anodes; Erbium - Used in radiography with tungsten anodes; Compensating filters used in general radiography are widely manufactured using aluminum due to its lightweight nature and its ability to effectively attenuate the x-ray beam.

Digital radiography in dentistry first introduced as "RadioVisioGraphy". [18] 1995: French company Signet introduce the first dental digital panoramic system. [19] First amorphous silicon and amorphous selenium detectors introduced. [20] [21] 2001: First commercial indirect CsI FPD for mammography and general radiography made available. [22] 2003
These detectors are rarely used for imaging and are only efficient at low energies. [17] Practical application in medical imaging started in the early 2000s. [18] Amorphous selenium is used in commercial large area flat panel X-ray detectors for mammography and general radiography due to its high spatial resolution and x-ray absorbing ...
