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.
Intraoral X-rays or a 3-D cone beam scan of the affected area can be used to obtain radiological images and confirm diagnosis of cysts in the periapical area. Circular or ovoid radiolucency surrounding the root tip of approximately 1-1.5 cm in diameter is indicative of the presence of a periapical cyst. [2]
A periapical granuloma (also referred to as an 'apical granuloma' or 'radicular granuloma') is a mass of chronically inflamed granulation tissue that forms at the apex of the root of a nonvital (dead) tooth. [12] (Although not a true granuloma, given the absence of granulomatous inflammation, the term 'periapical granuloma' is widely accepted ...
The three types are periapical cemental dysplasia (common in those of African descent), focal cemento-osseous dysplasia (Caucasians), and florid cemento-osseous dysplasia (African descent). Periapical occurs most commonly in the mandibular anterior teeth while focal appears predominantly in the mandibular posterior teeth and florid in both ...
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 ...
[11] [12] X-ray diagnostic methods are widely used in the practice of therapeutic dentistry (to detect peri- and periodontal diseases); in orthopedic dentistry (to assess the condition of preserved teeth, periapical tissues, periodontium, which determines the choice of orthopedic measures). Radiological methods are also in demand in ...
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Males tend to have larger teeth than females, [1] and tooth size also varies by race. [1] Abnormal tooth size is defined by some as when the dimensions are more than 2 standard deviations from the average. [1] Microdontia is when the teeth are abnormally small, and macrodontia is when the teeth are abnormally large.
