– The effectiveness of the C harters ', scrub, and roll methods of toothbrushing in removing plaque was studied in 182 college students. At an initial screening examination, plaque was assessed using the gingival index. These plaque scores were used to divide the group into those with poor and those with good oral cleanliness. Within each of the two groups, the subjects were randomly assigned to a toothbrushing method and to one of three instructors. Then the participants had their teeth cleaned and were asked to abstain from toothbrushing for one week. After this period of plaque accumulation the participants were again scored for plaque. The test subjects were carefully instructed in the particular tooth‐brushing method they were to use and the controls were asked to resume their usual methods. One week later the participants were again examined for plaque. An interaction between toothbrushing method and instructor was found indicating that the effectiveness of a particular method depended in part on the instructor. Nevertheless, the C harters ’and scrub methods of brushing appeared to be more effective in removing plaque. Generally, subjects with cleaner teeth prior to the stu achieved grater plaque reductions than those with initially poor oral cleanliness. All methods of bruching were relatively ineffective in removing proximal plaque.
