Six adult cotton ear marmosets (Callithrix jacchus) fed a vitamin C‐free synthetic diet of known composition developed overt evidence of ascorbic acid deficiency beginning 2 to 4 months after initiation of the test regimen. Three marmosets fed the identical diet plus a daily supplement of vitamin C served as controls. The animals were maintained on the vitamin C‐free diet until they became moribund and were killed and necropsied. The control animals were sacrificed following the death of the last of the test group. Comparative gross and histologic examinations of the periodontal structures revealed striking changes in the periodontal ligament of the scorbutic marmosets with relatively minor alterations in the osseous and gingival components. The periodontal involvement was largely confined to the alveolar segment and consisted of ligamental hemorrhages, loss of ligamental compactness and density, reduction in number of attachment fibers and loosening of the teeth.
