As on today in the market there are numerous manual toothbrush bristle designs and the media abounds with claims of superiority for dental plaque removal by individual brands. Objectives: 1.

The subjects were assessed for dental plaque prior to brushing, according to the criteria's of Turkeys and Gilmore modification of Quigley-Hein plaque index using two tone disclosing agent. After which the subjects were asked to brush for 2 minutes, and again scored for dental plaque using the same index.
