“…It has been claimed that the type of toothbrush used, the toothbrushing method, and the duration of brushing may be more important to the cleaning and whitening effect than the composition of the toothpaste. [ 7 ] As a matter of fact, in this in vitro study, these parameters were standard during toothbrushing in all the experimental groups focusing on the impact of the use of the tested toothpastes and mouthwash.…”

“…[ 1 20 ] It has been postulated that the abrasive potential of charcoal-containing toothpastes depends on the nature, method of preparation, and particle size distribution of the charcoal included in the product. [ 7 ] Previous studies reported a relatively high abrasivity of oral hygiene charcoal-based products. [ 21 ] In particular, in a clinical case, the use of a whitening toothpaste containing charcoal resulted in loss of the surface luster of the enamel and a dull appearance, implying a loss of surface tissue and increased surface roughness.…”

“…The abrasivity of charcoal-containing toothpastes is considered to depend on the nature, method of preparation, and particle size distribution of the charcoal included in the formulation. [ 7 ] The abrasivity of the toothpaste affects its effectiveness to remove extrinsic stains and deposits resulting to color change. However, high abrasivity of toothpaste may induce surface loss and changes in surface morphology of tooth tissues.…”

“…However, high abrasivity of toothpaste may induce surface loss and changes in surface morphology of tooth tissues. [ 7 ] Therefore, the objective of the present study was to investigate the effectiveness of a charcoal-containing whitening toothpaste on tooth color change and to evaluate the alterations of enamel surface that may be induced after simulation of toothbrushing corresponding to a 90-day period. Moreover, the influence of the use of a novel charcoal-containing whitening mouthwash on these properties was also examined in conjunction with the whitening toothpaste.…”

Purpose: The aim of this in vitro study was to investigate the effectiveness of a novel charcoal-containing whitening toothpaste and a mouthwash on tooth color change and the alterations of enamel that may be induced after toothbrushing, corresponding to a 90-day period. Materials and Methods: Forty human canines were used, stained with coffee, and divided into four groups ( n = 10) as follows: Group 1 (control) submitted to toothbrushing with deionized water, Group 2 with a regular toothpaste, Group 3 with a whitening toothpaste (1% charcoal), and Group 4 with the same whitening toothpaste in combination with a mouthwash (1% charcoal and 0.5% H 2 O 2 ). After the treatments, ΔΕ of the teeth was evaluated using an ultraviolet/Vis spectrophotometer, whereas the changes in surface morphology were observed by means of a confocal microscope. Results: The whitening toothpaste increased significantly ΔΕ (40.5%) compared to the control group ( P < 0.001). In addition, the tested whitening toothpaste also increased ΔΕ (17.7%) compared to the regular toothpaste ( P = 0.023). The whitening toothpaste presented smoother surfaces after toothbrushing, but more heterogeneous with numerous large craters, whereas the whitening mouthwash did not influence surface morphology changes. Conclusions: Charcoal-containing toothpastes may enhance the whitening of the teeth, but they should be used carefully due to changes that may induce on enamel. The patients should consult a dental professional for proper use. A charcoal-containing mouthwash in combination with whitening toothpastes probably cannot offer additional whitening effect.

“…Other promising examples of whitening dentifrices are those containing activated charcoal, which are available as toothpaste or powder products. Currently, activated charcoal is usually available in the form of fine particles that are extracted from charcoal by an oxidation process, either by reheating or by a controlled chemical process 5 . Most activated charcoal‐based dentifrices do not contain fluorides.…”

Objective To evaluate the effect of charcoal‐based dentifrices on the color change (CC) and surface wear (SW) of resin composites. Materials and Methods Five dentifrices, including three toothpastes: Colgate total‐12 (C12), Black is the new White (CPX), and Natural (NAT); and two powders: Carvvo (CVV) and Whitemax (WMX), were evaluated. Composite blocks (5x5x2mm‐ Z350 3 M/ESPE, shade A2) were subjected to 417 and 5004 brushing cycles. The CC (n = 7, CIEDE2000; ΔE00) was evaluated using a spectrophotometer. SW (n = 5) was assessed using profilometry. The dentifrice particles were characterized by scanning electron microscopy (SEM). Results In 417 brushing cycles, resin composite exhibited higher color change upon being exposed to NAT, CVV and WMC than to C12 (p ≤ 0.05). In 5004 brushing cycles, resin composite showed higher color change values when exposed to all dentifrices, except C12 (p ≤ 0.05). The powders promoted higher SW on resin composite than C12 in both evaluation times (p ≤ 0.05). In 417 cycles, WMX caused higher SW on composite than C12, CPX, and NAT (p ≤ 0.05). No significant different SW was found between powders and charcoal‐based toothpastes after 5004 brushing cycles (p > 0.05). SEM showed larger particles for powder than for toothpaste dentifrices. Conclusion Within the limitations of this study, both null hypotheses have been rejected. Resin composites exposed to charcoal‐based dentifrices exhibited significantly (p ≤ 0.05) higher color change and surface wear than conventional toothpastes. Clinical Significance Color change and surface wear shown by charcoal dentifrices may compromise the longevity of restorations.
