Which of the following is NOT a function of the periodontal ligament?

The periodontal ligament’s job is to suspend the tooth in the socket while supporting and remodeling the surrounding tissues. It transmits occlusal forces to the alveolar bone, anchors the tooth to bone via Sharpey’s fibers, and provides nourishment and cells for maintenance and repair of the surrounding tissues. Regeneration of enamel is not a function of the periodontal ligament because enamel is formed by ameloblasts during tooth development and, once mature, is non-vascular and not regenerated by PDL tissue. Enamel regeneration would require enamel-forming cells, not the PDL, so this option is the one that does not fit.
