Why do dental caries appear black dark in radiographs?
Cavities appear as a dark spot in a tooth. Cavities start in the enamel, which shows as the lightest color in the x-ray. It will travel inwards into the dentin, which is softer than enamel and appears darker too.
Can you see occlusal caries on radiograph?
The sensitivity of visual inspection can be augmented with radiography. Findings on bite-wing radiographs are useful indicators of dentinal decay on occlusal surfaces, and it is well recognized that the prevalence of occlusal caries may be underestimated without such imaging.
What do bitewing radiographs show?
Bitewing X-rays show details of the upper and lower teeth in one area of the mouth. Each bitewing shows a tooth from its crown (the exposed surface) to the level of the supporting bone. Bitewing X-rays detect decay between teeth and changes in the thickness of bone caused by gum disease.
Do Bitewings show cavities?
Bitewings are one of the most common sets of X-rays. Bitewings show teeth above the gum line and the height of the bone between teeth. Bitewings help diagnose gum disease and cavities between teeth. The bitewing X-ray is placed on the tongue side of your teeth and held in place by biting down on a cardboard tab.
What are interproximal radiographs primarily used to diagnose?
While they are used primarily to detect interproximal decay, they can also provide some information on the patient’s periodontal status. The height of the interproximal alveolar· bone margin relative to the cemento-enamel junction can be observed.
What is interproximal caries diagnosis?
Logicon is a new, revolutionary digital diagnostic tool for finding interproximal caries. It highlights suspicious regions in the radiographs and analytically reads the density level changes in the interproximal areas of the radiographs, giving a probability measure of the caries depth into enamel and dentin.
What is the difference between bitewing and a periapical image?
Bitewing radiographs, usually taken in a 4 film series, provide high resolution images of both sides of the mouth, targeting the rear of the jaw from the canines backward. Periapical radiographs can be used to target individual areas of the mouth, as well as the full mouth, and are usually taken in a longer series.
