The effectiveness of the Charters‘, scrub and roll methods of toothbrushing by professionals in removing plaque

The effectiveness of the Charters, scrub, and roll methods of toothbrushing by professional dental personnel in removing plaque was studied in 60 United States Army recruits. An interaction between method of brushing and brusher was found, indicating that no one method was clearly most effective in removing plaque. One brusher removed significantly more plaque with the Charters method than with the roll method, whereas the other brusher obtained a significantly greater reduction in plaque with the scrub method than with either the Charters or the roll methods.
