Question

On bite-wing radiographs of adults under the age of

30, the normal alveolar crest is
A. at the cementoenamel junction.
B. 1-2mm apical to the cementoenamel junction.
C. 3-4mm apical to the cementoenamel junction.
D. not clearly distinguishable

Answer 1

On bite-wing radiographs of adults under the age of 30, the normal alveolar crest is 1-2mm apical to the cementoenamel junction (CEJ).

Step-by-step explanation:

The normal alveolar crest on bite-wing radiographs of adults under the age of 30 is usually 1-2mm apical to the cementoenamel junction (CEJ). The cementoenamel junction is the junction between the enamel and cementum of the tooth. The alveolar crest refers to the top border of the alveolar process, which houses the teeth in their sockets. On bite-wing radiographs, the alveolar crest appears as a radiopaque line, and its position can provide information about the health of the underlying bone.
