“…On the other hand, in another recent study, it was reported that the use of an activated charcoal powder did not improve color change when combined with the tested regular and whitening toothpastes. [ 13 ] Moreover, in a recent literature review, the authors concluded that there is no sufficient evidence for whitening effect of charcoal-containing toothpastes. [ 5 ] It is interesting to mention that although in the current investigation, the charcoal-containing toothpaste presented statistically significant higher color change (ΔΕ = 11.17 ± 3.11) than the regular toothpaste (ΔΕ = 9.19 ± 1.69), this difference (×1.98) may not be clearly perceivable by the human eye.…”

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.

“…Vaz et al (8) conducted a study on the discoloration of whitening toothpastes on cattle incisors and found that there was no difference between toothpastes containing active coal, microparticles and hydrogen peroxide. Palandi et al (35) stated that activated charcoal powder does not increase discoloration when combined with normal and whitening toothpastes. In our study, unlike the studies in the literature, the best whitening effect on teeth was seen in toothpaste containing activated charcoal.…”

“…In our study, unlike the studies in the literature, the best whitening effect on teeth was seen in toothpaste containing activated charcoal. While bovine incisors were used in the studies in the literature, (8,35) human incisors were used in our study. The nature of the sample (human versus animal teeth) might be related with the difference in the results.…”

“…Toothpastes containing activated charcoal showed better effectiveness in whitening teeth than toothpastes containing blue covarine and hydrogen peroxide. However, it is stated in the literature that toothpastes containing activated charcoal increase the roughness of the enamel surface (35). In addition, individuals consume different beverages in daily life.…”

Objective: The desire of individuals to have whiter teeth increases the interest in tooth whitening products. Our aim was to in vitro study the whitening effect of hydrogen peroxide, blue covarine and active charcoal containing whitening toothpastes on human teeth. Materials and Methods: A total of 40 extracted human incisor teeth were used in the study. To measure the whitening effect of toothpastes, the teeth were divided into four subgroups and placed in the phantom tooth jaw model. Then, daily brushing was done with an electric toothbrush. The colors of the teeth were measured initially using the spectrophotometer (single point and bleached shade mode) and at the end of 7th, 14th and 28th days. Whitening effectiveness of toothpastes were studied according to CIEDE2000 formula (∆E00) and shade guide units (SGU). One-way analysis of variance (ANOVA) and Tukey test were used in the statistical analysis of the data. (p<0.05). Results: Activated charcoal containing toothpaste showed the greatest whitening effect at the end of 7th, 14th and 28th days (p<0.05). There was no statistically significant difference between the whitening effects of hydrogen peroxide and conventional toothpaste (p>0.05). Blue covarine containing toothpaste had statistically the lowest whitening effect (p<0.05). Conclusions: All toothpastes showed a whitening effect on the teeth after 7 days of use. Activated charcoal containing toothpaste showed more whitening effect after 28 days of use than hydrogen peroxide, blue covarine and traditional toothpaste.

“…In vitro studies have reported an increase in enamel surface roughness 6 and a decrease in microhardness 7 and immediate enamel bond strength 8 following at-home bleaching. These alterations to the enamel surface could result in pore formation and consequent entrapment of oxygen residuals released from the peroxide agents, which could, in turn, negatively interfere with the light curing of the adhesive agent.…”

Aim: This study evaluated the effect of a desensitizer agent (DES) during bleaching with 10% carbamide peroxide (CP) on enamel microshear bond strength (μSBS). Methods: Sixty bovine incisors were obtained and randomly distributed into groups (n=15): (C) Control: no desensitizing or bleaching, (DES) desensitizing gel application, (CP) bleaching with 10% CP and (CP/DES) bleaching with 10% CP combined with DES. Bleaching was performed for 6 h/day for 14 consecutive days. DES was applied for 8 h only on the 7th and 14th days of therapy. Specimens were stored in artificial saliva among the CP or DES applications and submitted to μSBS testing at three postrestoration times (n=5): 24 h, 7 days, and 14 days after bleaching using a universal testing machine. Failure modes were observed under a stereomicroscope. Data were analyzed by two-way ANOVA and Tukey’s test (α=5%). Results: Immediately after bleaching (24 h), CP promoted lower μSBS than the C and DES groups (p<0.05) but with no differences from the CP/DES. μSBS increased in the DES, CP, and CP/DES groups (p<0.05) when bonding was performed for 7 or 14 days elapsed from bleaching. CP/DES exhibited the highest μSBS among the groups 14 days after bleaching (p<0.05). Cohesive failure in enamel was predominant in the CP groups, while adhesive failure was mostly observed for the other groups. Conclusion: The use of a desensitizer during at-home bleaching maintained the enamel immediate bond strength, and its application favored bonding when the restoration was delayed for 14 days.
