1936Dunning & Davenport Dict. Dental Sci. 422/2 Periodontosis, a diseased condition of the periodontal membrane. 1942Orban & Weinmann in Jrnl. Periodontology XIII. 31 (heading) Diffuse atrophy of the alveolar bone (periodontosis). 1962Blake & Trott Periodontology iii. 28 Incidence of periodontal associated with alveolar bone destruction and pocket formation. This type of disease has been divided into chronic periodontitis.., which is inflammatory, and periodontosis.., which is principally degenerative. Periodontosis is often complicated by inflammation and the condition is then called periodontitis complex. 1975J. D. Manson Periodontics (ed. 3) xviii. 222 (heading) Juvenile periodontitis (‘periodontosis’). Ibid., Orban and Weinmann (1942) coined the term ‘periodontosis’ believing that the condition represented a degeneration of the periodontal ligament. However, there is no evidence for that belief. |
