Dental Intra Oral X-ray Positioner, Bite-wing

Dental X-rays (radiographs) are images of the teeth that a dentist uses to evaluate oral health. These X-rays are used with low levels of radiation to capture images of the interior of teeth and gums. This can help a dentist to identify problems, like cavities, tooth decay, and impacted teeth. This model depicts the positioning for a bite-wing x-ray. These x-rays show details of the upper and lower teeth in one area of the mouth. Each bite-wing shows a tooth from its crown (the exposed surface) to the level of the supporting bone. Bite-wing x-rays detect decay between teeth and changes in the thickness of bone caused by gum disease. Bite wing x-rays can also help determine the proper fit of a crown (a cap that completely encircles a tooth) or other restorations (eg, bridges). It can also see any wear or breakdown of dental fillings. This model is used in a digital handbook for a radiology practical for dentistry students.
