The 6-month intervention included 25 older adults with mild dementia or mild cognitive impairment, who were randomly assigned to Treatment Group 1 or Treatment Group 2. Treatment Group 1 (n = 7) received an educational booklet. Treatment Group 2 (n = 18) received a booklet, a tailored care plan for the participants with cognitive impairment and the care partner received four coaching sessions to learn to facilitate good oral hygiene. Both groups received electric toothbrushes. The study consisted of a 3-month active intervention and 3-month maintenance phase.
