Anatomy Flashcards
T/F: If the lamina dura is not seen, the tooth is not vital.
False
Presence means tooth is vital; absence does not mean much
What is the radioluncy often seen between the roots of the maxillary central incisors?
Incisive foramen
What radiopacity will be seen in near the spices of the mandibular incisors?
Genial tubercle
Near the mandibular molars, how do you differentiate between external oblique ridge and the mylohyoid ridge (internal oblique ridge)?
External - superior
Internal (mylohyoid) - inferior
How is the mandibular canal found?
Radiolucency inferior to the mylohyoid ridge
Where is the mental foramen commonly found?
Near apex of 2nd premolar
How is the submandibular (salivary gland) fossa found?
Radiolucency under the mandibular molars
What is a Stafne defect?
When the submandibular fossa pushes through the mandible - significant radiolucency near angle of mandible
What is a vertical radiolucent line in the midline between the maxillary centrals?
Intermaxillary suture
A V-shaped radiopacity near the middle of the nose in a maxillary central periapical.
Anterior nasal spine
What is the radiolucency between the maxillary canines and laterals?
Lateral fossa
Know it is not lesion because there are some mild trabeculations in it
In a max molar periapical, what structure would appear relatively straight superior to the maxillary sinus?
Floor of the nasal cavity/hard palate
What is the looping radiopaque line often appearing to go right through the max sinus in molar periapicals?
Zygomatic process
