Maxillary Radiolucencies
The radiolucent area above the maxillary molars and premolars
What is the maxillary sinus?
The radiopaque bulge distal to the third molar region
What is the maxillary tuberosity?
Radiolucent band that houses the inferior alveolar nerve and the blood vessels
What is the mandibular canal?
Ring shaped radiopacities located below the apices of mandibular incisors
What are the genial tubercles?
Tiny bumps of bone located on the lingual aspect of the mandible / attachment site of genioglossus and geniohyoid muscles
What are the genial tubercles?
The round or ovoid radiolucent area between the maxillary central incisors
What is the incisive foramen (nasopalatine foramen)?
The only mandibular landmark that shows in a maxillary radiograph
What is the coronoid process?
The small round or ovoid radiolucent area commonly seen in the apical region of the mandibular premolars
What is the mental foramen?
Triangular radiopacity superimposed over, or inferior to, the maxillary tuberosity region
What is the coronoid process?
The upper jaw composed of 2 paired bones
What is the maxilla?
The thin radiolucent line located between the maxillary central incisors
What is the median palatal suture?
The small hooklike projection sometimes seen posterior to the maxillary tuberosity area
What is the hamulus?
Small radiolucent dot found inferior to the apices of the mandibular anterior teeth
What is the lingual foramen?
The horseshoe shaped bone that lies below the mandible, sometimes appearing as a "floating" curved
radiopacity
What is the hyoid bone?
The largest and strongest bone of the face
What is the mandible?
Appears as a vertical radiolucent band superimposed over the ramus of the mandible
What is the glossopharyngeal airspace?
The inverted Y is commonly found here.
What is above the maxillary canine?
The vertical radiolucent lines readily seen in areas of thin bone; most often seen in the anterior mandible
What are the nutrient canals?
Radiopaque band extending downward and forward from the anterior border of the mandibular ramus
What is the external oblique ridge?
Tube-like passages through bone that contain nerves and blood vessels that supply the teeth
What are nutrient canals?
A diagonal radiolucent band located superior to the radiopaque shadow of the soft palate and uvula
What is the nasopharyngeal air space?
The J or U shaped radiopacity that is located superior to the maxillary first molar region
What is the zygomatic process of the maxilla?
Radiolucent area found in molar region below the mylohyoid ridge
What is the submandibular fossa?
Dense radiopaque band that extends downward and forward from the molar region
What is the mylohyoid ridge?
The THREE main parts of the mandible
What are the:
