WebbSharpey fibers are part of the principal collagenous fibers of the periodontal ligament. These fibers are embedded in the cementum and the alveolar bone which attach the tooth to the alveolus. When the cementum is visible on the teeth, this suggests that there is root exposure. This often occurs as a result of gingival recession.

Webbrection of Sharpey's fibers in cementum and bone has a relationship to the deposition of both cementum and bone. This suggests that new layers of cementum become nec essary when change in position produces bending of Sharpey's fibers at the point of insertion into cementum. 2.
