Toothbrush abrasivity in a long-term simulation on human dentin depends on brushing mode and bristle arrangement.

ABSTRACT:

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.

Project description:OBJECTIVES:In adult participants, what is, following a single brushing exercise, the efficacy of a powered toothbrush (PTB) as compared to a manual toothbrush (MTB) on plaque removal? METHODS:MEDLINE-PubMed and Cochrane-CENTRAL were searched from inception to February 2019. The inclusion criteria were (randomized) controlled clinical trials conducted in human subjects ?18 years of age, in good general health and without periodontitis, orthodontic treatment, implants and/or removable prosthesis. Papers evaluating a PTB compared with a MTB in a single brushing exercise were included. When plaque scores were assessed according to the Quigley-Hein plaque index (Q&HPI) or the Rustogi modified Navy plaque index (RMNPI). From the eligible studies, data were extracted. A meta-analysis and subanalysis for brands and mode of action being oscillating-rotating (OR) and side-to-side (SS) were performed when feasible. RESULTS:Independent screening of 3450 unique papers resulted in 17 eligible publications presenting 36 comparisons. In total, 28 comparisons assessed toothbrushing efficacy according to the Q&HPI and eight comparisons used the RMNPI. Results showed a significant effect in favour of the PTB. The difference of Means (DiffM) was -0.14 (P < 0.001; 95%CI [-0.19; -0.09]) for the Q&HPI and -0.10 (P < 0.001; 95%CI [-0.14; -0.06]) for the RMNPI, respectively. The subanalysis on the OR mode of action showed a DiffM -0.16 (P < 0.001; 95%CI [-0.22, -0.10]) for the Q&HPI. For the SS mode of action using RMNPI, the DiffM showed -0.10 (P < 0.001; 95%CI [-0.15; -0.05]). The subanalysis for brands showed for the P&G OR PTB using the Q&HPI a DiffM of -0.15 (P < 0.001; 95%CI [-0.22; -0.08]) and the Colgate SS for RMNPI showed a DiffM of -0.15 (P < 0.001; 95%CI [-0.18; -0.12]). CONCLUSION:There is moderate certainty that the PTB was more effective than the MTB with respect to plaque removal following a single brushing exercise independent of the plaque index scale that was used.
