A combined analysis of a toothbrush, foam brush, and a chlorhexidine-soaked foam brush in maintaining oral hygiene.

Oral hygiene in immunocompromised patients is important in preventing oral infection and may be important in preventing systemic infections. By mechanically reducing bacterial plaque levels in the oral cavity, the risk of infection may be reduced. Foam brushes have been shown to be ineffective in controlling plaque levels and gingivitis. In a 2-week trial, we demonstrated that using a foam brush soaked in chlorhexidine reduces plaque and controls gingivitis as effectively as using a toothbrush. Foam brushes soaked in chlorhexidine should be used when toothbrushing cannot be performed.
