A clinical trial comparing the effectiveness of a three-headed versus a conventional toothbrush for oral hygiene in children.

AIM: The study was designed to compare the efficacy of the Superbrush three-headed with a conventional brush for oral hygiene in children. MATERIALS AND METHODS: The study population was 78 children attending three primary schools in Leeds (UK). The clinical trial consisted of a single blind, randomized, four visits, crossover and single use toothbrush design. Subjects were randomized to one of two test groups (A and B). The 16-week trial consisted of four visits with a washout period of four weeks between the second and third visits. Both brushes were used with a horizontal mini-scrubbing strokes technique. Plaque scores were recorded at each visit using the Quigley and Hein Plaque Index as modified by Turesky et al. [1970]. RESULTS: Using a paired t-test the results from the outcome measures of the four visits indicated that buccally the conventional brush was superior in plaque removal to the three- headed brush, lingually there was no difference between brushes. Although over-all plaque removal was similar for both brushes, 85% of the children preferred the Superbrush. CONCLUSION: Significant improvements in plaque removal in children can be achieved following good tooth brushing instructions regardless of the design of toothbrush used.
