Abrasion Behaviour of Different Charcoal Toothpastes When Using Electric Toothbrushes

Abstract

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.

Remineralization, color stability and surface roughness of tooth enamel brushed with activated charcoal‐based products

“…However, ACPs could be too abrasive for daily use and could increase in the surface roughness 12 . Previous studies demonstrated that ACTs are more abrasive than conventional toothpastes 10,11 . However, in the present study, ACPs presented similar surface roughness to that of the fluoride toothpaste (without charcoal particles), expect for fluoride‐free charcoal group 12 …”

“…12 Previous studies demonstrated that ACTs are more abrasive than conventional toothpastes. 10,11 However, in the present study, ACPs presented similar surface roughness to that of the fluoride toothpaste (without charcoal particles), expect for fluoride-free charcoal group. 12 All the toothpastes have hydrated silica as abrasive particles that could create scratches on the tooth surface and increase the surface roughness.…”

“…Some ACPs have relatively high abrasivity 7 . Continued use of ACPs can cause enamel wear and dentin exposure facilitating caries development and yellowing of the teeth 7,10,11 . It has been stated that ACPs have fractal‐shaped abrasive particles that cause scratches and some mineral loss in the enamel surface, increasing its surface roughness 12 .…”

“…Sendo assim, é importante ressaltar que uma abrasão contínua provoca diminuição na espessura do esmalte dental, influenciando diretamente na cor do dente, que também é alterada em função da deposição de cromóforos provenientes da dieta, e esta deposição pode ser acelerada devido a porosidade e rugosidade superficial do esmalte (Dionysopoulos et al, 2020). Ainda, sabe-se que o esmalte quando está pré-danificado/amolecido é mais facilmente desgastado (Greuling et al, 2021).…”

“…Alguns autores alegam que o tipo da escova de dente, a técnica e o tempo de escovação influenciam tanto na limpeza quanto no desgaste abrasivo do elemento dentário (Dionysopoulos et al, 2020;Greuling et al, 2021;Vural et al, 2021;Osmanaj et al, 2022). Já no estudo de Rodrigues et al, (2019) não houve diferença significativa quanto ao tipo de escova.…”
