X-ray (Dental)

X-ray (Dental) refers to radiographic images produced by exposing oral structures to a small, controlled amount of ionising radiation so that the internal anatomy of teeth, roots and supporting bone can be examined. Common types include bitewing, periapical and panoramic radiographs and three-dimensional cone beam CT scans; these images reveal problems such as tooth decay between teeth, abscesses, fractures, impacted teeth and bone loss that are not visible during a clinical examination.

The procedure is usually quick and involves positioning a sensor or film inside the mouth or placing a machine outside the head while a trained operator takes the image, which a dentist or specialist then interprets to guide diagnosis and treatment planning. Dental X-rays use low doses of radiation and standard safety measures such as lead aprons and digital sensors are used to minimise exposure, while CBCT is reserved for complex cases that require detailed three-dimensional views.
