The purpose of the present study was to develop and evaluate educational approaches specifically for improvement of oral hygiene behaviour amongst institutionalised elderly. A sample of 201 residents, 48-99 yr of age (mean age 82 yr), was selected from four different institutions in Lothian, Scotland. A clinical examination and a structured interview were conducted immediately before and 2 months after the termination of the programme. The four institutions were blind to the examiner and randomly allocated to a control group or one of the three programmes; 1) active involvement of staff only; 2) active involvement of residents only; 3) active involvement of both residents and staff. The programme comprised three 1-h sessions at monthly intervals in groups of five to six residents or members of staff. The analysis of the results showed poor oral health and oral hygiene, high objective need for oral care but low perceived need. The programme had little impact on most of the included variables and only about half of the participants remembered the programme 2 months after its termination. The implications of the study are that groups of elderly need to be differentiated further so that only well and not confused elderly participate in programmes such as this and less well and confused elderly receive regular professional support with oral hygiene.
