Which anatomical landmark is found in the maxillary posterior region of a panoramic radiograph?
Middle cranial fossa
Which anatomical landmark is found in both the maxillary anterior AND posterior region of a panoramic radiograph?
Hard palate
Which anatomical landmark is found in the mandibular anterior region of a panoramic radiograph?
Mental ridge
Which anatomical landmark is found in the mandibular posterior region of a panoramic radiograph?
Submandibular fossa
Which of the following is described by soft tissue observed at the edges of panoramic radiographs as faint radiopaque outlines superimposed over the styloid process, anterior and inferior to the mastoid process?
Ear
Which of the following is described by the radiolucency between the palate and tongue that presents if the tongue is not correctly positioned against the palate during panoramic exposures?
Palatoglossal air space
Is panoramic radiography based on the principles of tomography?
TRUE
Can skills developed for interpretation of intraoral radiographs be expanded and adapted for successful interpretation of panoramic images?
TRUE
Is a panoramic image unable to separate structures to make it possible to focus on a narrow slice of tissue at a time?
FALSE
In panoramic imaging, are three-dimensional structures of the head and neck broadened and flattened?
TRUE
Is the goal of panoramic technology to isolate and produce a blurred image of the dental arches?
FALSE
Will all anatomical features of the maxilla and mandible recorded on intraoral radiographs also be recorded on panoramic images?
TRUE
Do genial tubercles appear on a panoramic radiograph as a radiopaque, donut-shaped circle surrounding the lingual foramen?
TRUE
Will the glossopharyngeal air space appear on a panoramic radiograph as an open area posterior to the tongue?
TRUE
Is the nasopharyngeal air space located between the tongue and the palate?
FALSE
Do ghost images and negative shadows enhance interpretation?
FALSE
Are panoramic images unable to record additional bones and structures of the maxillofacial region?
FALSE
Can panoramic images possibly record cartilage and calcifications of ligaments located in the neck?
TRUE
Are soft tissues recorded by panoramic images?
FALSE
Must panoramic images be interpreted by the dentist for all deviations from normal anatomy?
TRUE
Is it not possible to identify carotid arterial plaques on some panoramic images?
FALSE
Do air spaces appear with varying degrees of radiopacity on panoramic images?
FALSE
Can air spaces compromise the diagnostic ability of the panoramic radiograph?
TRUE
Are panoramic machine parts sometimes recorded on panoramic images?
TRUE
Could a ghost image appear on the left side of a clearly recorded right side mandible?
TRUE
Are some anatomical structures more readily observed than others on panoramic images?
TRUE
What is the name of the anatomic landmark that appears on a panoramic image as a long, narrow radiopaque spine extending downward from the inferior surface of the temporal bone?
Styloid process
What is the name of the anatomic landmark that appears on a panoramic image as a round, radiolucent opening in the temporal bone located anterior and superior of the mastoid process?
External auditory meatus
What is the name of the anatomic landmark that appears on a panoramic image as a radiopaque, winglike bony projection of the sphenoid bone located posterior to the maxillary tuberosity?
Lateral pterygoid plate
What is the name of the anatomic landmark that appears on a panoramic image as a concave, depressed area of the temporal bone located anterior to the external auditory meatus?
Glenoid fossa
What is the name of the anatomic landmark that appears on a panoramic image as a pea-shaped, radiolucent opening in the bone located between the roots of the maxillary central incisors?
Incisive foramen
What is the name of the anatomic landmark that appears on a panoramic image as a thick radiopaque horizontal band superior to the maxillary teeth?
Hard palate
What is the name of the anatomic landmark that appears on a panoramic image as a radiolucent ovoid or round opening in the center of the ramus of the mandible?
Mandibular foramen
What is the name of the anatomic landmark that appears on a panoramic image as a radiolucent, tunnel-like passageway outlined by two thin radiopaque lines?
Mandibular canal
What is the name of the anatomic landmark that appears on a panoramic image as a radiolucent, round opening on the body of the mandible, near the roots of the mandibular premolars?
Mental foramen
What causes the unusual anatomical relationships on panoramic images that are not seen on intraoral radiographs?
The principles of tomography cause wide broadening of the dental arches combined with superimposition of structures.
