Host tissue response in chronic periodontal disease

This is the authors' abstract. We don't add key points for this paper.

The normal periodontium and manifestations of gingival and periodontal disease were studied in 120 living marmosets ( Saguinus oedipus ) and in the skulls of 40 additional animals to determine the possible usefulness of the marmoset as a model for investigation of the host tissue response in chronic periodontal disease. The general clinical and anatomic features of the animal are very similar to those seen in man; however, most of the adult animals exhibit severe occlusal abrasion and evidence of occlusal traumatism. Although gingival inflammation was observed in almost all of the animals examined, only 18.2% of the total gingival units were affected and the severity was exceptionallly limited. The prevalence of bony lesions indicative of the presence of chronic inflammatory periodontal disease was 0.5% and all of the lesions observed were associated with open contacts or plunger cusps. Thus, the prevalence of spontaneous chronic progressive periodontal disease in wild‐trapped marmosetes appears to be very low.
