title: Plaque removal efficacy of two children's toothbrushes: a one-month study.
abstract: Reach Wonder Grip toothbrush for children was evaluated for plaque removal efficacy and compared to the Colgate Plus Junior (extra soft). The subjects appeared at the test site with overnight (14-18 hours) plaque accumulation. After qualifying for the study, sixty-eight (68) subjects were randomly assigned one of the test brushes. They then participated in the test evaluation at the clinical site wherein plaque levels were measured before and after a one minute brushing. Plaque removal efficacy was evaluated by the Global Plaque Index (percent of tooth surface covered by stained deposit). The subjects then used the assigned toothbrush at home for one month and returned to the test site to repeat the baseline evaluations. After their final plaque evaluations, the subjects were given a new toothbrush from each brand to use at home for one week and the subject and the parent were asked to complete a preference questionnaire. Sixty-seven (67) subjects completed the one month study. After one month's use of twice per day brushing, neither of the test toothbrushes demonstrated any evidence of oral irritation that could be related to toothbrushing. The results indicated that Reach Wonder Grip for Children was significantly more effective (p < 0.05) than Colgate Plus Junior in removing overall (Global) plaque at the initial exam period. The preference questionnaire indicated that the Reach Wonder Grip toothbrush was preferred by both the children and their parents. It is concluded that the new Reach Wonder Grip toothbrush for children is safe and effective for plaque removal.
