title: Effects of toothbrush design and brushing proficiency on plaque removal.
abstract: A single-blind, short-term cross-over clinical trial compared the plaque removal performance of three commercially available manual toothbrushes. A sample of 25 dental hygiene students, 19 to 42 years old, served as participants. On 3 separate occasions, participants were instructed to refrain from toothbrushing or flossing for 24 hours before clinical trials. A prebrushing plaque index using disclosing solution was performed on each participant. One of the 3 test brushes was then randomly dispensed to each participant, and they were allowed to brush for 90 seconds without the aid of a mirror. A postbrushing plaque index was then performed on each participant. This procedure was repeated 2 more times at 2-week intervals so that each participant was tested with all 3 toothbrushes. Previous studies of this kind using random participant samples have suggested that brush design does indeed affect the efficacy of plaque removal. This study used participants who were well versed on efficient toothbrushing technique to determine if improved brushing skills would overshadow advantages in toothbrush design. No significant differences in performance were detected between the test brushes for any of the three scored areas.
