Purpose: The aim of this study was to evaluate plaque removal with a 360° toothbrush by comparing the manual and sonic 360° toothbrushes to a standard manual and electric toothbrush, using a pediatric typodont model painted with Kilgore International, Inc. Artificial Plaque.
Methods: Pediatric typodont models were painted with Kilgore International, Inc. Artificial Plaque. and brushed with 4 different pediatric toothbrushes for the amount of time recommended by the manufacturer. The toothbrushes tested were the Oral-B Pro-Health Stages 2 Manual Toothbrush, Oral-B Kids Battery Powered toothbrush, AutoBrush 360° Manual Toothbrush, and AutoBrush 360° Sonic Toothbrush. The smooth surfaces of every tooth were then blind scored by 3 different calibrated examiners using the Turesky Modified Quigley-Hein Plaque Index. Each tooth was visually divided into 6 sections and given a 0-5 score based on the amount of remaining artificial plaque.
Results: The Manual AutoBrush had the highest overall plaque score (2, 95% CI = 1.59-2.4), highest MF/DF/ML/DL scores (2.1, 95% CI = 1.68-2.53), and MID-L/MID-F scores 1.78 (1.43-2.13). This was statistically higher than all other toothbrushes overall (all pairwise p<=.026) and for MID-L/MID-F surfaces (all pairwise p<=.052). For the MF/DF/ML/DL surfaces, it was statistically higher than the Manual and Electric (p <.001) but not the Sonic AutoBrush (p=.052). The Manual and Electric toothbrush plaque scores were not statistically different overall (p=.161), for MF/DF/ML/DL (p=.127) or for MID-L/MID-F (p=.231). The Sonic Autobrush had plaque scores higher than electric and manual toothbrushes for all surfaces (all p<.001).
Conclusions: The AutoBrush Manual Kids and AutoBrush Sonic Kids toothbrushes were significantly less efficient at plaque removal on all teeth compared to the manual and electric toothbrushes. Both AutoBrush toothbrushes had significant plaque remaining on all posterior teeth compared to the anterior teeth.
