[Preventive dentistry 6. Prevention of caries in frail older people].
Many older people have a bad oral health, with (root) caries a prevalent cause. Alarming results of research projects raise the question whether sufficient preventive measures are being taken to prevent the development and progress of (root) caries in frail older people. A review of the recent literature revealed that in frail older people and physically or cognitively impaired adults, daily use of a 5,000 ppm fluoride toothpaste and quarterly application of chlorhexidine or sodium fluoride can decrease by half the risk of root caries. In the Netherlands, toothpaste containing 5,000 ppm fluoride is not (yet) on the market. At the present time, only the advice brochure 'Prevention of root caries' is available. Another measure to prevent deterioration of oral health among frail older people is paying attention to frail older people who do not visit their dentist on a regular basis due to physical limitations and care dependency. When this is the case, it is necessary to intensify professional oral healthcare with instructions to personal caregivers and professional care providers in order to fight (root) caries.
