An evaluation of the effectiveness of four mechanical plaque-removal devices when used by a trained care-provider.

Many care-dependent elderly individuals live in nursing homes and must depend on nursing home aides for oral hygiene care. It is generally agreed that the level of oral hygiene care among care-dependent nursing home residents is less than optimal. Two reasons are time constraints and the difficulty involved in brushing other individuals' teeth. The identification of effective and efficient plaque-removal devices for use by care-providers should make it easier for nursing home aides to incorporate effective oral hygiene care into their daily routines. This pilot study was undertaken to determine the relative effectiveness of four plaque removal devices with different basic designs when used by a non-professional care-provider on 10 healthy volunteers. A brush with curved bristles on the lateral aspect of the brush head and short straight bristles in the center (Collis-curve) and an electric toothbrush with tufts that rotate reciprocally (Interplak) were the most effective, a conventional brush (Oral-B) was somewhat less effective, and a disposable foam brush (Abco) was least effective and similar to the prebrushing plaque score (baseline). All the volunteers reported that the Collis-curve was the most comfortable brush, and the care-provider reported that it was the easiest to use.
