“…Lima et al [23] also investigated the substance loss for one of the toothpastes used in this study (Curaprox Black is White). They used a brushing simulator with manual toothbrushes and 30,000 brushing strokes and a force of 1.5 N. The authors obtained a substance loss of~16 µm.…”

Abrasion Behaviour of Different Charcoal Toothpastes When Using Electric Toothbrushes

2021

Objectives: The purpose of this in vitro study was to compare the abrasion behaviour of different charcoal toothpastes when brushing with electric toothbrushes on human enamel. Materials and Methods: A self-designed brushing machine was built using six commercially available electric toothbrushes in abrasion chambers. Each chamber was constantly supplied with a toothpaste–water mix. Pieces of human enamel, which were embedded in PMMA, were brushed for 4 h. Before and after brushing, profilometer measurements were performed in order to determine the substance loss due to brushing. Results: The following calculated mean removal values (mean ± SD) were found: (4.6 ± 0.6) µm (Group C: Splat Blackwood), (3.2 ± 0.9) µm (Group D: Curaprox Black is White), (2.3 ± 0.7) µm (Group B: Sensodyne Pro Schmelz), (1.7 ± 0.6) µm (Group A: Water), (1.4 ± 0.6) µm (Group E: Prokudent Black Brilliant). A post hoc Tukey HSD test (p = 0.05) showed that the results for Group A/B/E, Group B/D and Group C each lie within subsets that differ statistically significantly from the other subsets. Conclusions: Within the limitations of this in vitro study, it can be stated that some charcoal toothpastes lead to significantly higher abrasion on human enamel, when brushing with electric brushes. Clinical Relevance: As low-abrasion toothpaste is generally advisable, and some charcoal toothpastes should be viewed critically with regard to their abrasive properties.

“…Assuming a 1 Hz frequency, this would result in 8 h of brushing, resulting in 8 µm enamel loss in 4 h (it was 3.2 µm in 4 h in the study at hand). However, as the authors in [23] used bovine enamel and manual toothbrushes, differences are to be expected.…”

“…In addition, it is of great importance that dentifrices, in general, present moderate-to-low abrasiveness in order to prevent enamel surface alterations (such as roughness or microhardness) and, especially, tooth wear (17, 36,42). Mainly, the general advice is to avoid whitening dentifrices for the patients with a higher risk of developing erosive tooth wear (ETW) (42), particularly if the dentin is exposed (43), but the literature is very controversial regarding the real effects or correlations between the abrasiveness of the whitening dentifrices and ETW (44)(45)(46)(47)(48).…”

Effectiveness and Adverse Effects of Over-the-Counter Whitening Products on Dental Tissues

et al. 2021

The role of bleaching agents (e.g., hydrogen peroxide) in tooth bleaching is quite well-described in a few literature studies and considered as the option choice for those desiring brighter teeth, but alternative methods have emerged to fulfill the desire of patients in a faster, easier, and cheaper way. In this context, whitening over-the-counter (OTC) products are available in several vehicles, such as toothpaste, rinses, gums, paint-on varnishes, and strips, but their effectiveness in terms of bleaching is questioned. This review aimed to describe their mode of action, whitening effectiveness, and harmful effects associated with the indiscriminate use of these products. Dentifrices usually present a combination of abrasives that can induce damage to the tooth surface without evidence of promoting real bleaching. The same was found for rinses, which might present a low pH, with an erosive potential. Charcoal has been included in the composition of these products to improve their whitening effect but there is no evidence supporting it. Regarding strips, they present hydrogen peroxide in a variety of concentrations and are the only OTC products able to promote bleaching. Despite the vehicle, an indication for the use of these products should be made after a careful individual diagnosis of the etiology of the dental staining, considering that most of them seem to be effective only in removing extrinsic stains or preventing their formation over enamel. Also, their indiscriminate use might induce damage and deleterious effects over tooth tissues or gingival tissues. The dentist should be aware of the composition and mode of action of each individual product as they change according to the composition and the vehicle used to recommend the best mode of usage. Still, there is no sound evidence that any of the described OTC products promote a better bleaching effect than the products indicated for a professional.

Introdução: Dentes brancos e alinhados são constantemente associados à saúde bucal, boa aceitação psicossocial e melhora da autoestima. O clareamento dental é um procedimento não invasivo e de resultados rápidos para tratamento de pigmentações intrínsecas e extrínsecas, através de reações químicas de oxirredução. Com a crescente demanda estética por dentes mais brancos, alternativas mais baratas e de fácil acesso, como o uso de dentifrícios branqueadores, estão sendo cada vez mais procuradas por quem tem interesse em melhorar a aparência do sorriso. Objetivo: Revisar a literatura acerca do uso de cremes dentais branqueadores em Odontologia. Método: Foram pesquisados em bases de dados com as palavras-chave “tooth bleaching”, “tooth whitening”, “activated charcoal”, “whitening toothpaste”, 31 artigos publicados entre os anos de 2016 e 2020.
