[Dental aspects of aging].

The oral cavity fulfils important functions also at an older age in life. In getting older the chances to loose quality in these functions will increase. The following three problem areas are relevant in this respect: teeth can decay by dental caries or by progressive wear; the gums and periodontal tissues may develop serious inflammation and degeneration; finally after extraction of teeth dentures can be provided, but may create new problems in turn. Dental life can be extended by preventive measures and restorative treatment. New developments in the areas of so-called adhesive dentistry and dental implantology may contribute to quality improvement. Based on recently published epidemiological data and on computer simulation studies it is expected that there will be no major changes in need and supply for dental care in the dutch population. However, care spent on children and adults will shift towards care for adults and elderly.
