Maxillary Periapical Imaging and Nasal Anatomy Quiz

Bony Structures

• A linear prominence or projection of bone is a crest.
• A small bump or nodule of bone is a tubercle.
• A rounded prominence of bone is a process.

Joints

• An immovable joint that represents a line of union between adjoining bones of the skull is a suture.

Bone Types

• Compact bone in the human body is dense and appears radiopaque on a dental image.
• Cancellous bone in the human body is composed of a spongy, porous structure.

Radiography

• Accurate mounting and interpretation of intraoral images are enabled by the use of a reference line.

Coronoid Process

• The coronoid process is a triangular-shaped projection of bone that serves as an attachment site for the temporalis muscle.

Density

• The densest structure in the human body is enamel.

Pulp Cavity

• The composition of the pulp cavity includes soft tissue, pulp, and nerves.

Alveolar Crest

• The alveolar crest appears as a thin, curved radiopacity in the anterior region.

Maxillary Sinuses

• The maxillary sinuses are the largest paranasal sinuses and are located in the maxillary bones.

Inferior Nasal Conchae

• The appearance of the inferior nasal conchae on an anterior maxillary periapical image is a curved, radiopaque structure.

Maxillary Sinus Floor

• The composition of the floor of the maxillary sinus is bone.

Genial Tubercles

• The genial tubercles are located on the lingual aspect of the mandible.

Mental Ridge

• The mental ridge is a bony prominence located on the labial aspect of the mandible, and it serves as an attachment site for the mentalis muscle.

Mental Foramen

• The mental foramen appears as a radiolucency on a mandibular periapical image.

Mandibular Canal

• The appearance of the mandibular canal on a mandibular periapical image is a radiolucent channel.

Mylohyoid Ridge

• The mylohyoid ridge is located on the lingual aspect of the mandible and appears as a radiopaque, curved structure on a mandibular periapical image.
