Oral hygiene and oral health are a major concern for long-term-care facility residents who are unable to care for themselves. In this six-week study, the efficacy of a sonic toothbrush (Sonicare) was compared with traditional manual brushing in a setting where hygiene care was provided by caregivers. Evaluations of plaque levels were made at baseline and at 2, 4, and 6 weeks according to the Silness and Löe index. The sonic brush was found to be significantly superior to the manual brush over the trial period (MANCOVA; p = 0.026). Plaque reduction at 6 weeks was found to be 38% with the sonic brush and 6% with the manual brush. The results indicate that the sonic brush may be an effective way to provide improved oral health to nursing home subjects when oral care is caregiver-provided.
