In vitro assessment of activated charcoal‐based dental products

Abstract

Objective Assess the effects of activated charcoal‐based products on whitening and changes on dental enamel surface. Material and Methods Fifty‐two blocks of bovine dental enamel were randomly distributed in four groups (n = 13): brushing with activated charcoal‐based powder (PW); brushing with activated charcoal‐based dentifrice (AC); brushing with a conventional dentifrice containing 1450 ppm of fluoride (CD); and whitening with 10% carbamide peroxide (CP). Color, microhardness, and surface alteration were analyzed at baseline and after 14 days of treatment. Three samples per group were randomly selected and examined using scanning electron microscopy (SEM) to analyze the morphology. Results PW exhibited greater color change for the ΔE00, ΔWID, Δb* and ΔL* parameters than other groups (p < 0.05). After treatment, microhardness decreased in AC and CP groups (p < 0.05). Also, PW and AC groups showed more surface alteration than CD and CP (p < 0.001). Changes in the morphology of dental enamel were observed by SEM in PW and AC groups. Conclusion Activated charcoal‐based products showed a lower whitening effect than 10% carbamide peroxide. These products also influenced dental enamel microhardness, resulting in greater surface alteration. Clinical Significance Activated charcoal‐based products promoted minimum whitening effects with significant enamel surface alteration. The 10% carbamide peroxide was more effective for whitening and caused slight enamel surface alteration.

Comparison Between the Effect of Normal Saline, Calcium Hydroxide and Colloidal Gold /Charcoal Extract Combination on Two Isolated Strains From Dental Canals – Enterococcus Faecalis and Streptococcus Mutans-

“…In dentistry, activated charcoal has been used in toothpaste formulations and oral care products due to its potential to adsorb bacteria and toxins from the oral cavity. 12 Gold nanoparticles, on the other hand, have unique properties that make them attractive for biomedical applications. They possess a large surface area-to-volume ratio, which enhances their reactivity.…”

Effect of aging and fiber‐reinforcement on color stability, translucency, and microhardness of single‐shade resin composites versus multi‐shade resin composite

“…Each measurement was repeated three times and the average value was recorded. The CIELab values (L*, a*, and b*) were obtained, and the ΔE 00 value from before to after thermocycling was calculated using the CIEDE2000 formula system 49,50 : where ΔL′, ΔC′, and ΔH′ are the differences in lightness, chroma, and hue between the two samples compared. The weighting functions for the lightness, chroma, and hue components were S L , S C , and S H , respectively.…”
