What is Density and Contrast? Density is the overall darkness (blackness) of an image. Contrast is the difference in lightness and darkness between areas on a radiograph. The goal in dental radiology is to use techniques that require the least amount of radiation exposure to produce images with the right amount of density and contrast.

Periapical cysts result from infection of the tooth, which spreads to the apex and into the adjacent bone. This leads to apical periodontitis, granuloma formation and eventual cyst formation. These cysts are therefore centered on the apex of the tooth and tend to be small, most <1 cm. There is also unsurprisingly usually overt evidence of caries.
Most radicular cysts appear as round- or pear-shaped, unilocular, lucent lesions in the periapical region 3. They are usually <1 cm in diameter and are bordered by a thin rim of cortical bone. The associated tooth usually has a deep restoration or large carious lesion. Caries will appear as erosion of the enamel/crown of the associated tooth. MRI i...
Jun 29, 2022 · Periapical radiolucencies are commonly observed findings on OPG and other dental/head and neck imaging modalities. Differential diagnosis. They can represent a number of pathologies: periapical lucency related to apical periodontitis. periapical granuloma. periapical abscess. periapical cyst. cemento-osseous dysplasia.
