You notice a horizontal, radiopacity superior to the maxillary teeth on yourpatient’s panoramic radiograph. This radiopaque structure is the:

A	tongue
B	palatoglossal air space
C	hard palate
D	coronoid process

Explanation:

Detailed explanation-1: -Palatoglossal air space – a radiolucent band that lies superior to the apices of the maxillary teeth and inferior to the hard palate.

Detailed explanation-2: -In a periapical radiograph, the enamel, which is the hardest substance in the human body, appears as the most radiopaque (lightest) part of the crown of the tooth. The dentin is a less-mineralized hard structure of the tooth between the enamel and the pulp and is not as radiopaque as the enamel.

Detailed explanation-3: -Tooth enamel and amalgams look white (radiopaque). Tissues and bone are less dense and allow more X-‐rays to reach the film. Therefore, tissue and bone look darker (radiolucent).

Detailed explanation-4: -Which of the following would appear radiopaque on a dental image? Dentin is an example of a radiopaque structure.
