Lamina Dura is a thin layer of dense bone that lines the tooth socket, or alveolus, in the jaw. It plays a crucial role in supporting teeth by providing a stable foundation. This layer is essential for the attachment of the periodontal ligament, which connects the tooth to the surrounding bone. The presence of Lamina Dura can be observed on dental X-rays as a radiopaque line around the roots of teeth. Its health is important for overall dental stability, and changes in its appearance can indicate various dental conditions, such as periodontal disease or tooth loss.
