Plaque Removal Efficacy of an Innovative U-Shaped Sonic Toothbrush
Objectives: To evaluate the safety and plaque removal efficacy of a new children’s u-shaped sonic toothbrush compared to a marketed children’s manual toothbrush.
Methods: Twenty-two healthy children (5-8 years old) were enrolled in a single-center, single-use, randomized, two-period, IRB approved cross-over study. Subjects were randomly assigned to one of two treatment sequences: 1) brush two minutes with marketed children’s manual toothbrush (MTB) or 2) brush 30 seconds with AutoBrush® 360° Sonic Toothbrush (AB) and fluoride toothpaste. Qualified subjects had pre-brushing supragingival plaque levels ≥ 1.8 according to the Lobene-Soparkar Modified Plaque Index (PI), following 12-16 hours plaque accumulation period. Under parent’s supervision, subjects brushed at home with their assigned toothbrush, twice daily during a 2-day familiarization period. After refraining (12-16 hours) from oral hygiene, subjects returned for plaque assessment, supervised use of their assigned toothbrush and a post-brushing plaque evaluation. Subjects were given the second toothbrush to begin the next 2-day familiarization period and second period evaluation procedures. Analysis of covariance (ANCOVA) used for single-use brushing PI models assessed whole mouth and 8 other hard-to-reach tooth sites.
Results: There were no product related adverse events; both brushes were well tolerated. A total of 22 children (9 males and 13 females) completed the study. Baseline plaque scores were comparable for each sequence. Compared to baseline levels, both toothbrushes significantly reduced plaque with the exception of the proximal and lingual sites for the MTB. Between group analysis showed that AB provided statistically significantly greater reductions (p<0.001) in plaque mean scores than the MTB for whole mouth (50%), gumline (69.7%), proximal (40%) and the other 5 hard-to-reach tooth sites.
Conclusions: Children brushing for 30 seconds with the AutoBrush® 360° Sonic Toothbrush demonstrated significantly more effective than 2 minutes with MTB in whole-mouth plaque removal as well as the hard-to-reach tooth areas.
