Santé parodontale et besoins en soins parodontaux d'un échantillon de la population belge.

An epidemiological survey was carried out of among staff members of the Catholic University of Louvain. A total of 402 subjects, age 35 to 65, were examined. Periodontal lesions were estimated using the CPITN index (WHO). Only one subject presented no signs of gingival bleeding in any part of the mouth. 41.4% of the subjects presented a deep periodontal pocket in at least one sextant. Many subjects, although not presenting deep or moderately deep periodontal pockets (28.5%) needed scaling and rootplanning or other treatments to eliminate plaque retentive factors. In this sample, representing a socio-economically favoured segment of the population, we revealed a significant prevalence of periodontal disease from mild chronic gingivitis to deep pockets. Requirements in terms of care are considerable, ranging from oral hygiene instruction to control plaque to specialised care.
