The periodontium of old marmosets is characterized by a narrow, serrated cribriform plate of alveolar bone, a loss of tinctorial identification of Sharpey's fibers and a decrease in the cellular elements of the periodontal ligament. The attachment fibers are frequently calcified. In contrast to the blue periodontal ligament and pink alveolar bone in alcian blue‐PAS stained sections of adult marmosets, the periodontal ligament stains pink and the alveolar hone deep red in old animals. Aged marmosets also have degenerative changes in the periodontal vasculature not seen in younger adults. The changes are similar to those described in aged human periodontal tissues.
