What is the compact bone that lines the tooth socket referred to as?

Lamina Dura
Alveolar Bone
Cementum
Periodontal Ligament

The correct answer is: Lamina Dura

The compact bone that lines the tooth socket is referred to as the lamina dura. This structure is crucial for dental health as it provides support and stability for the tooth by forming a secure environment in which the tooth root is anchored. The lamina dura appears radiopaque on dental radiographs and is an important indicator of bone health around teeth. Recognizing the lamina dura is essential for dental professionals when assessing periodontal health, as changes in its appearance can signal issues such as bone loss or periodontal disease. Understanding this term helps in properly interpreting radiographic images and determining the health of the dental structures surrounding the teeth.
