alveolar bone surrounds the roots of teeth to provide support and creates what is commonly called an alveolus, or "socket".
lying over the bone is the gingiva, which is readily visible in the mouth.
the periodontal ligament is a specialized connective tissue that attaches the cementum of a tooth to the alveolar bone.
this tissue covers the root of the tooth within the bone.
each ligament has a width of 0.15 - 0.38 mm, but this size decreases over time
the functions of the periodontal ligaments include attachment of the tooth to the bone, support for the tooth, formation and resorption of bone during tooth movement, sensation, and eruption.
the cells of the periodontal ligaments include osteoblasts, osteoclasts, fibroblasts, macrophages, cementoblasts, and epithelial cell rests of Malassez.
consisting of mostly type I and III collagen, the fibers are grouped in bundles and named according to their location.
