Patients and methods

the intervention group comprised 151 patients (84.4 ± 5.6 years) and the control group 118 patients (84.7 ± 5.2 years). An interview and a clinical examination were carried out before a tailored intervention of oral and denture hygiene. The participants in both groups were re-interviewed and re-examined after 6 months.


the intervention significantly reduced the number of plaque covered teeth and improved denture hygiene. In addition, functional ability and cognitive function were significantly associated with better oral hygiene.
