“…Indeed, the microhardness diminished after application of both types of toothpaste in composite specimens but the difference was not noticeable. Concurring with the present study results, Farghal and Elkafrawy [ 9 ] showed no significant difference between control group (distilled water) and charcoal-containing toothpaste (Perfect White Black) in both microfilled (Heliomolar) and nanohybrid (Tg-nanohybrid) composite resins. Although higher wear and diminished hardness were reported as the side effects of using the activated charcoal [ 7 , 9 , 29 ], this study could not confirm the negative effect of charcoal on enamel hardness.…”

“…It seems the amount of roughness resulting from using charcoal dentifrices on resin composites may be affected by the filler composition and distribution. In Farghal and Elkafrawy [ 9 ] study, both tested composites indicated significant surface roughness after using charcoal-containing toothpaste. However, the microfilled composite presented generally lower surface roughness than nanohybrid composite.…”

“…Furthermore, the retention of charcoal particles in the gingival sulcus and formation of surface defects such as deep pits plus fissures on restorations result in compromised esthetic of teeth colored restorations [ 21 ]. Farghal and Elkafrawy [ 9 ] indicated the adverse effect of activated charcoal on surface roughness and microhardness of microfilled and nanohybrid composite resins. Thus, more evidence is required to assess the performance and safety of these products, and relying on only manufacturers' claims is not logical.…”

Background and Objectives. Charcoal-containing toothpastes have become popular among many patients; however, there is inadequate scientific evidence on oral health. This study aimed to evaluate the color change, surface microhardness, and roughness of bovine enamel and composite resin submitted to simulated toothbrushing with a whitening toothpaste containing activated charcoal. Methods. Thirty-six bovine incisors and resin composite samples were prepared, stained with black tea, and then randomly divided into two groups. The samples were brushed with a charcoal-containing toothpaste (Colgate® MAX WHITE) and daily toothpaste (Colgate® Max Fresh) for 10,000 cycles. Before and after brushing cycles, color variables (ΔL, Δa, Δb), total color change (ΔE), plus Vickers microhardness were evaluated. Two samples of each group were prepared for surface roughness assessment via atomic force microscope. Data were analyzed by Shapiro–Wilk, Independent sample t-test and Mann–Whitney U tests. Results. According to the obtained results, ΔE and ΔL were significantly higher whereas Δa and Δb were noticeably lower in charcoal-containing toothpaste group in comparison with daily toothpaste in both composite and enamel samples. The microhardness of samples brushed with Colgate® MAX WHITE was significantly higher than that of Colgate® Max Fresh in enamel ( P = 0.04 ), whereas no significant difference was found in composite resin samples ( P = 0.23 ). Colgate® MAX WHITE enhanced the roughness of both enamel and composite surfaces. Conclusion. The charcoal-containing toothpaste could improve the color of both enamel and resin composite with no negative effect on microhardness. Nevertheless, its adverse roughening effect should be considered occasionally on composite restorations.

INTRODUCTION: There has been increase in demand to use natural whitening agents nowadays which include activated charcoal. Activated charcoal has gained popularity recently with various claims to its benefits that have not been proven. AIM: The aim of the study was to evaluate the effect of activated charcoal whitening agents and regular whitening tooth paste on enamel surface of first premolars and to compare between the effects of materials used. MATERIALS AND METHODS: Twenty-one mandibular first premolars were used and divided into control group: untreated teeth that were later incorporated into experimental group. Experimental group: Consisting of three subgroups: Subgroup I: treated with Carbon Coco. Subgroup II: treated with Venu activated charcoal. Subgroup III: treated with Crest 3D white. Brushing was done nine s for 30 days then teeth were preserved in artificial saliva. RESULTS: Scanning electron microscopic results showed areas with rodless enamel more observed in Subgroup III than Subgroups I and II. EREs were more numerous on Subgroups I and II than Subgroup III on enamel surface. Partially occluded EREs with precipitates were more observed on Subgroups I and II than Subgroup III. Energy dispersive X-ray analysis results for calcium showed significant increase between all groups with control. The highest value was recorded in Subgroup II followed by Subgroups I and III while control group was the lowest one. Phosphorous showed significant increase between all groups with control. The highest value was recorded in Subgroup I followed by Subgroups III and II while control group was the lowest one. Micro-hardness results of Subgroups I and II showed significant increase compared to control group and no significant difference between control and Subgroup III was detected. CONCLUSION: Powder form activated charcoal is more abrasive than whitening toothpastes. There is no visible difference between pure 100% activated charcoal powder and charcoal powder with additives to it.v

“…In recent years, there has been increasing interest in calcium carbonate nanoparticles (CaCO 3 NPs) from various industrial fields. [1][2][3][4][5] Besides their excellent biocompatibility and biodegradability, they present numerous advantages for cosmetic formulations and biomedical applications. [6][7][8][9][10][11][12] For instance, they are intensively investigated for drug delivery, diagnostics and tumour therapy due to their pH responsive and buffering properties.…”
