[Periodontal disease in Belgian adults]

Background: To date, no epidemiological study has been published on the periodontal health of the Belgian population. The aim of this study was to rectify this situation and determine the extent of the problem in Belgium. Methods: A prevalence survey was carried out in a representative sample of employees of the Catholic University of Louvain. A total of 402 people aged between 35 and 65 were examined. Periodontal suffering was estimated using the CPITN index (WHO), which determines the most affected sextant of a mouth in order to assign a code to the mouth as a whole. At the same time, treatment needs were evaluated. Results: Only one subject was considered healthy, i.e. there was no bleeding of the gums in any part of the mouth. At the same time, 41.4% of the subjects examined exhibited a deep periodontal pocket in at least one sextant of the mouth likely to progress to the loss of the teeth. Many mouths (28.5%), which were free from moderate or deep pockets, had to be scaled and polished or to be treated in order to eliminate other factors which could lead to a build-up of tartar. Conclusion: In this study population representative of a socio-economically favored stratum of the Belgian population, we observed a high prevalence of periodontal diseases, grading from mild chronic gingivitis to the deep cavities which are observed when the bone supporting the tooth has been lost. At the same time, we uncovered many needs for periodontal care, ranging from instruction on how to control the dental plaque to specialized periodontal care via careful scaling and polishing
