In dental terminology, how would one define 'cortical bone'?

Soft tissue surrounding the teeth
The hard outer wall of the maxilla and mandible
A type of dental restoration material
The inner layer of the alveolar bone

The correct answer is: The hard outer wall of the maxilla and mandible

Cortical bone refers to the dense, hard outer layer of bone that forms the outer walls of the maxilla (upper jaw) and mandible (lower jaw). This type of bone is crucial in providing structural support and strength to the jaws and protects adjacent tissues and structures. Cortical bone is significantly denser than cancellous bone, which is the spongy inner layer, allowing it to withstand various forces during activities such as chewing and biting. Its hardness is essential for maintaining the shape and integrity of the jawbone, making it a critical component of dental and orthodontic health. The importance of understanding cortical bone lies in its role in both the foundation of teeth and the overall function of the dental arch.
