The opening to the pulp canal at the apex (terminal end) of the root of the tooth. A three-rooted tooth would have three apical foramina.
One of the four basic tooth structures. The thin layer of dense tissue that covers the root of a tooth. Because the cementum layer is thin, it is generally radiographically undistinguishable from dentin.
The solid, outer portion of the dense, compact bone. Appears very radiopaque on radiographs
Cranial bone that forms the forehead
Shedding of primary teeth
Occasionally imaged on a radiograph as a tiny radiolucent dot indication the small opening in the tubelike passageway of a nutrient canal.
The area at the posterior and inferior corners of the mandible, where the body of the mandible meets and joins the ascending ramus of the mandible.
-Small opening on the lateral side of the body of the mandible.
Usually observed near the apices of the premolars
An opening in the temporal bone located superior and anterior to the mastoid process
Thin bony extensions of the nasal wall.
A very small hook like process of the bone that extends downward and slightly backward from the sphenoid bone. Appears radiopaque and can occasionally be seen posterior to the max. tuberosity.
Dense cartilage that separates the right basal fossa from the left. Appears as a vertical radiopaque line separating the paired radiolucencies of the nasal cavity.
A rounded knob or projection on a bone, usually where the bone articulates (joins) with another bone. The condyle of the mandible articulates with the glenoid fossa (depression) of the temporal bone
Appears radiolucent, with thin radiopaque lines above and below outlining the cortical bone that lines the canal
Also known as Trabecular Bone; the softer spongy bone that makes up the bulk of the inside portion of most bones. The cells of trabecular bone vary in size and density
Large air space divided into two paired radiolucencies by the radiopaque nasal septum. Visible above the roots of the incisors.
