Dense structures. Allow less radiant energy to pass through. Electrons reach receptor
with less energy. Results in white (light) image.

Radiopaque Structures
,If patient's teeth are too far forward on bite stick, teeth appear thin and blurry. Front
teeth should be aligned with groove on bite stick.

Positioning of Anterior Teeth (too far forward on bite stick)
Two openings on mandible supplying lower lip with blood vessels. Located in apical
region of mandibular premolars. Small round radiolucent area.

Mental Foramen
Bone that surrounds tooth. Radiopaque.

Alveolar bone
Identify neoplasms, impacted teeth, supernumerary teeth and anomalies. Used as an
adjunct to intraoral images.

, Extraoral Radiographs
If patient's teeth are too far back on focal trough, teeth appear fat and blurry. Front
teeth should be aligned with groove on bite stick.

Positioning of Posterior Teeth (too far back on bite stick)
Bony wall of tooth socket that surrounds the root. Thin radiopaque line around the
root.

Lamina dura
Boney projection portion of cheekbone. Above maxillary molars, anterior to zygoma.
J or U shaped radiopaque structure.

Zygomatic process of maxilla
Used for PAs when paralleling isn't possible. Tooth and image receptor form an angle
where they meet at the long axis of the tooth. PID is parallel to the bisecting angle of
