3 types of Extraoral Radiology
panoramic

what color are radiolucent areas on a radiograph?
Black
why are radiolucent areas black ?
Structures that are cavities, depressions, or openings in bone such as a sinus, fossa, canal or foramen will allow x-rays to penetrate through them and expose the receptor.
what color are radiopaque areas on radiographs?
white
why are radiopaque areas white?
Structures that are bony in origin absorb or stop the penetration of the x-rays and, therefore, do not reach the receptor
True or False
Some structures partially absorb radiation and are represented in varying degrees of radiopacity
True
The incisive foramen appears…
between the roots of the central incisor teeth as a round to oval radiolucency less than one centimeter in diameter
What x-ray does the incisive foramen show up on?
maxillary central incisor periapical images
what maxillary anterior landmark does this radiograph show?
incisive foramen
On what radiograph does the lingual foramen appear?
mandibular incisor periapical images
The lingual foreman is…
a small pin-point opening in bone on the lingual aspect of the anterior mandible for the lingual nerve and arteries
What mandibular anterior landmark is shown?
lingual foreman
What is the ADA’s standard for viewing and interpreting intraoral radiographic images
labial mounting or arrangement
*this standard applies regardless of the type of receptor that is used
what is labial mounting or arrangement
orientation presents the survey as if the clinician is facing the patient’s oral cavity with the views arranged and organized anatomically according to the patient’s right and left sides
