Alveolar bone loss in wild baboons

Radiograph‐based methods were used to assess alveolar bone loss in 12 juvenile and 18 adult baboons ( Papio hamadryas , sensu lato) living in the Awash National Park, Ethiopia. Alveolar bone loss, as measured from the cementoenamel junction to the alveolar crest, averaged about 1 mm in juveniles and about 1.5 mm in adults. Densitometry of alveolar bone from the radiographs provides a baseline for comparisons with other adult baboons. Periodontal disease surveys of baboon populations using such methods may identify potential etiological agents. Such knowledge may contribute to a better understanding of periodontal disease etiology in humans. © 1993 Wiley‐Liss, Inc.
