A comparative evaluation of the Scrub and Bass Methods of toothbrushing with flossing as an adjunct (in fifth and sixth graders).

The Scrub and Bass Methods of toothbrushing with flossing as an adjunct were evaluated to determine which is most effective in eliminating or reducing plaque and gingivitis in 5th and 6th grade school children. Three hundred and eleven children were randomly selected and placed in five groups (Scrub, Scrub-Floss, Bass, Bass-Floss, Comparison). Four Method groups went through four weeks of daily supervised toothbrushing with four dental hygienists, while the Comparison group received no supervised instructions. There was a marked effect on oral hygiene and gingival conditions at the end of the experimental period in all four groups with no one method superior to another. Peer group intercommunication probably accounts for the improvement in the comparison group.
