Dental Admissions Test (DAT) Practice Test

What type of bone is primarily found in the alveolar process?

1. Cortical bone

2. Cancellous bone

3. Spongey bone

4. Compact bone

The correct answer is: Cortical bone

The type of bone primarily found in the alveolar process is cortical bone. The alveolar process, which is the bony ridge in the jaw that contains the sockets for teeth, is made up of dense, compact structures that provide strength and support. Cortical bone, often referred to as compact bone, forms the outer layer of the bone and contains a dense arrangement of bone tissue. This density is crucial for withstanding the forces generated during chewing and other dental functions. While cancellous bone (sometimes known as spongy bone) exists in other parts of the bone structure, it is more porous and typically found within the interior of bones, rather than in the alveolar process where strength and stability are paramount. The alveolar process must be robust enough to hold teeth securely, which is why the presence of cortical bone is predominant in that area. It is essential for dental professionals to understand the types of bone present in the alveolar process to assess dental health and perform procedures effectively.
