Toothbrush abrasivity in a long-term simulation on human dentin depends on brushing mode and bristle arrangement |pdf=|usr=}}{{28222156}} gab.com Text Toothbrush abrasivity in a long-term simulation on human dentin depends on brushing mode and bristle arrangement JO: PLoS One http://www.kidney.de/pget.php?&tw=1&pmid=28222156 #FOAvip Objective: The aim of this study was to evaluate the susceptibility of dentin to brushing abrasion using four different toothbrushes (rotating-oscillating, sonic and two types of manual toothbrushes) with the same brushing forces. Methods: Dentin samples (n = 72) were selected from 72 impacted third molars. Half of the surface of dentin samples was covered with an adhesive tape, creating a protected and a freely exposed area in the same specimen. Brushing was performed with either a: sonic (Sonicare PowerUp, Philips GmbH, Hamburg, Germany), b: oscillating-rotating (Oral B Vitality Precisions Clean, Procter & Gamble, Schwalbach am Taunus, Germany) or two different manual toothbrushes c: flat trim brush head toothbrush (Dr. Best: Original, Glaxo-Smith-Kline, Bühl, Germany) and d: rippled-shaped brush head toothbrush (Blend-a-Dent, Complete V-Interdental, Blend-a-med, Schwalbach, Germany) in a custom made automatic brushing machine. The brushing force was set to 2 N and a whitening toothpaste (RDA = 150) was used. The simulation period was performed over a calculated period to mimic a brushing behavior of two times a day brushing for eight years and six months. Dentin loss was quantitatively determined by profilometry and statistically analyzed by Wilcoxon and Mann-Whitney-U Test (p < 0.05). Results: The mean (standard deviation) surface loss was 21.03 (±1.26) ?m for the sonic toothbrush, 15.71 (±0.85) ?m for the oscillating-rotating toothbrush, 6.13 (±1.24) ?m for the manual toothbrush with flat trim brush head and 2.50 (±0.43) ?m for the manual toothbrush with rippled-shaped brush head. Differences between all groups were statistically significant at p<0.05. Conclusion: Using the same brushing force and a highly abrasive toothpaste, manual toothbrushes are significantly less abrasive compared to power toothbrushes for an 8.5?year simulation.
