[Black dentifrice, white teeth?]
Activated charcoal toothpastes lack strong scientific proof for whitening. Studies show they are less effective than other whitening toothpastes and evidence for cosmetic benefits is insufficient.
Area of Science:
- Dental Science
- Cosmetic Dentistry
- Materials Science
Background:
- Activated charcoal toothpastes are marketed for teeth whitening.
- Scientific validation of their efficacy is limited.
- Consumer interest in charcoal dental products is high.
Purpose of the Study:
- To evaluate the scientific evidence supporting the teeth-whitening claims of activated charcoal dentifrices.
- To assess the effectiveness of charcoal-based toothpastes in reducing extrinsic tooth staining.
Main Methods:
- A literature search was conducted in PubMed.
- One randomized controlled double-blinded in vitro study was analyzed.
- Systematic reviews and review articles on charcoal dentifrices were examined.
Main Results:
- One study indicated the 'Black is White Curaprox®' dentifrice was less effective in stain reduction compared to other whitening toothpastes.
- A systematic literature review found insufficient evidence for charcoal dentifrices' whitening effects.
- A separate review article corroborated the lack of substantial scientific backing for cosmetic benefits.
Conclusions:
- Current scientific evidence does not substantiate the teeth-whitening claims of activated charcoal dentifrices.
- Further rigorous research is needed to confirm or refute the efficacy of these products.
- Consumers should be aware of the limited scientific support for charcoal toothpaste whitening.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
01:18Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
