An enterolith is a mineral concretion or calculus formed anywhere in the gastrointestinal system. Enteroliths are uncommon and usually incidental findings but, once found, they require at a minimum watchful waiting. If there is evidence of complications, they must be removed.
Calculus was a term used for various kinds of stones. This spun off many modern words, including calculate (' use stones for mathematical purposes '), and calculus, which came to be used, in the 18th century, for accidental or incidental mineral buildups in human and animal bodies, like kidney stones and minerals on teeth.

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.
In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...
Xeroradiography is a type of X-ray imaging in which a picture of the body is recorded on paper rather than on film.In this technique, a plate of selenium, which rests on a thin layer of aluminium oxide, is charged uniformly by passing it in front of a scorotron. [1]
A calculus (plural calculi) is a hard, stone-like concretion that forms within an organ or duct inside the body. They are usually made from mineral salts , and other types of calculi include tonsiloliths (tonsil stones) and renal calculi (kidney stones).
Most patients are asymptomatic and the condition is only found during radiographic analyses. In a study, 14.7% of patients were symptomatic, with pain being the most common symptom and may be associated with osteomyelitis. [2] Other symptoms may include hypoesthesia, paresthesia, and discomfort. [3]
The roentgen or röntgen (/ ˈ r ɛ n t ɡ ə n,-dʒ ə n, ˈ r ʌ n t-/; [2] symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
