Study Notes
Bone Structure
- The dense outer layer of bone is compact bone.
- Cancellous bone is composed of a network of trabeculae and bone marrow.
Radiodensity
- Compact bone resists the passage of the x-ray beam and appears radiopaque on a dental image.
Bone Projections
- A linear prominence or projection of bone is an example of a crest.
- A small bump or nodule of bone is an example of a tubercle.
- A rounded prominence of bone is an example of a condyle.
- An opening or hole in bone that permits the passage of nerves and blood vessels is an example of a foramen.
Nasal Cavity
- The radiopaque area that appears as a V-shaped structure located at the intersection of the floor of the nasal cavity and the nasal septum is the nasal spine.
- The wafer-thin, curved plates of bone that extend from the lateral walls of the nasal cavity are called turbinate bones.
Sinuses
- The maxillary sinuses are located superior to the maxillary premolar and molar teeth.
Dental Image
- The intersection of the maxillary sinus and the nasal cavity as viewed on a dental image is called the nasal cavity floor.
Mandibular Structures
- The structure that appears as a radiolucent area in the molar region below the mylohyoid ridge on a mandibular periapical image is the submandibular fossa.
Density
- The densest structure found in the human body is the enamel of a tooth.
Radiopaque Structures
- The dense radiopaque line that surrounds the root of a tooth on a dental image is the lamina dura.
- The alveolar crest tends to appear less dense and less radiopaque on a dental image, especially in the posterior region.
Foramen and Fossae
- The lingual foramen is a communication between the mandible and the mylohyoid nerve.
- Nutrient canals contain blood vessels and nerves that supply the tooth.
- The mental ridge is a bony prominence on the buccal surface of the mandible.
- The mental fossa is a depression on the buccal surface of the mandible.
