Radiology Chapter 19

Method used to examine the interproximal surfaces of teeth.

Between two adjacent surfaces.

Intraoral radiographic examination used to inspect the crowns of both the maxillary and the mandibular teeth on a single film.

Type of film used in the interproximal examination. The bite-wing film has a "wing" or tab, and the patient "bites" on the wing to stabilize the film.

Bone that supports and encases the roots of the teeth.

Coronal portion of alveolar bone found between the teeth.

Areas of a tooth that touches an adjacent tooth; the area where adjacent tooth surfaces contact each other.

On a dental radiograph, open contacts appear as thin radiolucent lines between adjacent tooth surfaces.

On a dental radiograph, the area where the contact area of one tooth is superimposed over the contact area of an adjacent tooth.

The film is placed in the mouth parallel to the crowns of both the upper and the lower teeth.  The film is stabilized when the patient bites on the bite-wing tab or bite-wing film holder.  The central ray of the x-ray beam is directed through the contacts of the teeth, using a vertical angulation of +10.

Device used to position an intraoral film in the mouth and retain the film in position during the exposure.  They eliminate the need for the patient to stabilize the film.

Includes plastic bite-blocks, plastic aiming rings, and metal indicator arms.  They help assist in the alignment of the PID and reduces the amount of radiation.

Position-indicating device.  An open-ended, lead-lined cylinder extending from the opening of the metal housing of the tubehead; aims and shapes the x-ray beam (also called the cone).

A heavy-paperboard tab or loop fitted around a periapical film and used to stabilize the film during the exposure.
