Is there a difference in the response of basal and alveolar bone to pressure?

1. No difference

2. Basal responds more than alveolar

3. Alveolar responds more than basal

4. Yes, there is a difference

The correct answer is: Yes, there is a difference

There is a difference in the response of basal and alveolar bone to pressure. Basal bone is the thicker, denser bone found at the base of the alveolar bone, which surrounds and supports the teeth. It is responsible for providing support for the teeth and withstanding the forces of chewing and biting. Alveolar bone is found closer to the teeth and is responsible for attaching the teeth to the basal bone. While both types of bone may respond to pressure, basal bone is typically more resistant and responds less than alveolar bone, which is more flexible and can adapt to changes. Therefore, the correct answer is D, as the statement "there is a difference" is accurate. Options A, B, and C are incorrect as they imply that there is no difference or that only one type of bone responds to pressure more, rather than acknowledging that there is a difference in their
