Periodontal diseases at present are distinguished as multifactorial, resulting from the interaction between periodontal pathogenic bacterium and the immune response mechanism of the host. This inflammatory reaction affects periodontal tissues, including alveolar bones. Sice the frequency of such pathology is currently high, our objective was to detect its presence in a contemporary skeletal series. The observed sample consisted of 35 crania from the osteological collection ?Prof. Dr. Rómulo Lambre? (School of Medical Sciences, University of La Plata, Argentina), belonging to adult individuals (23 males and 12 females). A total of 14 crania were eliminated toshow total reabsorption in both alveolar arcades. In the remaining 20 crania, horizontal and vertical alveolar bone loss was macroscopically observed with the help of a Mitutoyo Digital Caliper (0.01 mm of precision). Frequencies were calculated for each feature and for each dental piece. The results showed that 75% of the sample presents features attributable to periodontal diseases. Fenestrations and dehiscences were observed in 55% of the crania analyzed. These results coincide with the high prevalence of such pathology recorded in the specified clinical bibliography.
