What is the width range of a normal periodontal ligament space?

The width range of a normal periodontal ligament space is typically considered to be between 0.25 to 0.5 mm. This space surrounds the roots of teeth and plays a crucial role in providing support and shock absorption during activities such as chewing.

A periodontal ligament space within this range indicates healthy dental conditions, where the periodontal attachment is intact and functioning properly. Measurements outside of this range may suggest pathological conditions, such as periodontal disease or other dental issues.
