Flashcards
Mental Foramen
Mental Foramen
A radiolucent area located at the apex of mandibular premolars. It appears as a dark, oval-shaped space on radiographs.
Zygomatic Process
Zygomatic Process
A radiopaque structure, often appearing as a 'U' shape on radiographs. It's formed by the cheekbone and extends toward the ear.
Lateral Cephalometric View
Lateral Cephalometric View
A projection used in dentistry that captures a lateral view of the skull, highlighting the soft tissue outlines of the face.
