Dental Intra oral X-ray Positioner, Periapical

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. The positioner depicted in this model is used for a Pericapical x-ray of teeth of the lower jaw. It shows the whole tooth: from crown to beyond the rooth where the tooth attaches into the jaw. Each periapical x-ray shows all teeth in one portion of either the upper of lower jaw. Periapical x-rays detect any unusual changes in the root and surrounding bone structures. This model is used in a digital handbook for a radiology practical for dentistry students.
