Correct answer: C. More than the other parts of alveolar bone
- A. Same as in other parts of alveolar bone
- B. Less than the other parts of alveolar bone
- C. More than the other parts of alveolar bone

Explanation
The lamina dura is a dense, highly mineralized part of the alveolar bone proper, so its calcium content is greater than that of the less dense supporting alveolar bone. Its radiopaque appearance on dental radiographs reflects this density.
