Relative dentin and enamel abrasivity of charcoal toothpastes


Zoller, Manuel Joseph. Relative dentin and enamel abrasivity of charcoal toothpastes. 2022, University of Zurich, Faculty of Medicine.

Abstract

Objectives: Very little data are known about charcoal toothpastes. The aim of this study was to counteract the missing data by determining the relative dentin abrasivity (RDA) and relative enamel abrasivity (REA) values of charcoal toothpastes.
Methods: Radioactively charged dentin and enamel samples were randomly divided into groups of eight specimens. Each group was brushed with two of total 12 charcoal toothpaste slurries and with a standard abrasive with a known RDA and REA value. The measured radioactivity in counts per minute within the slurries corresponds to the amount of dentin or enamel abraded. RDA and REA values of the charcoal toothpastes were expressed relative to the known value of the standard slurry.
Results: The RDA and REA values of the charcoal toothpastes have a broad range of 24-166 and 0-14, respectively.
Conclusions: The RDA and REA values do not differ significantly from previously tested commercially available toothpastes. However, the lack of fluoride compounds in many of the investigated charcoal toothpastes can have a less beneficial effect for the consumers. It is very important to educate patients accordingly.
