“…The average particle size of toothpaste containing activated charcoal is larger than that of plain toothpaste [ 17 ], with the star-shaped of coal particles also increasing the surface wear. The roughened surface is prone to retention of plaque, stains, and food debris, as well as increases the risk of caries and periodontal inflammation [ 18 , 19 ]. They may also reduce the mechanical properties of enamel such as surface hardness [ 20 ].…”

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.

“…1 However, they contain abrasives that can contribute to tooth wear, dentin sensitivity, 2 and cervical tooth abrasions. [2][3][4][5] With exposure of cementum due to gingival recession, abrasives in toothpaste become a major causative factor in non-carious cervical lesions (NCCL). [4][5][6][7] Knowledge and awareness of the abrasiveness of toothpastes may help in the prevention of cervical abrasions and dentin sensitivity.…”

Background. Relative Dentin Abrasivity (RDA), as set by ISO 11609, is a standardized measurement on the abrasiveness of toothpaste. There are no published RDA values for Philippine-brand toothpastes. This study evaluated the degree of abrasion of five Philippine-brand toothpastes.Objective. To compare qualitatively and quantitatively the abrasivity of five Philippine-brand toothpastes (Brands X, U, H, HN, G) to two foreign-brand toothpastes Brand C (RDA 68) and Brand P (RDA 150).Methods. Twenty-four bovine dentin samples were brushed with a slurry of each of the toothpaste using a toothbrushing machine. A profilometer, scanning electron microscope and a visual measuring scope were used to determine abrasivity through the before-and-after-brushing surface roughness.Results. Ranked based on the difference of the means for surface roughness, before-and-after brushing, in decreasing order of abrasivity are: Brands P, X, U, H, C, HN, and G. Using Dunn's test-post hoc test for Kruskal-Wallis test at p ≤ 0.05, we showed that the abrasivity of Brands G, H, and HN were not significantly different from Brand C, and Brand X was not significantly different from Brand P. Brand U was significantly less abrasive than Brand P and significantly more abrasive than Brand C. Conclusion.Brands G, H, and HN can be considered as low-abrasive toothpastes, Brand X a high abrasive toothpaste, and with Brand U was unclear as to category. Findings from qualitative data support the quantitative data.

Objective To evaluate the in vitro effects of two commonly used commercial herbal toothpastes (Dabur Meswak and Patanjali Dant Kanti) on the colour stability, surface texture, and microhardness of two commonly used aesthetic restorative materials, i.e., nanofilled composite and resin-modified glass ionomer cement (NFC and RMGIC). Materials and methods The samples were brushed twice daily using two herbal toothpastes, Dabur Meswak (Dabur India Ltd) and Patanjali Dant Kanti (Patanjali Ayurved Ltd, India) and powered toothbrush. Atomic force microscopy, spectroscopy, and digital micro hardness testing were used to estimate the changes in the surface roughness, colour change, and hardness of the samples, respectively, at baseline and after six months. Results Regarding colour change, a statistically significant difference (P < 0.05) was observed between baseline and six months in both the RMGIC and NFC for both herbal toothpastes. Both RMGIC and NFC had higher Ra values when brushed with either toothpaste, indicating a rough surface. The greatest increase in the mean difference in microhardness was observed for the Patanjali Dant Kanti toothpaste samples brushed on both NFC and RMGIC. Conclusion In our work, herbal toothpaste increased surface roughness and microhardness and caused colour changes in the two most commonly used aesthetic restorative materials. Clinical relevance Herbal toothpastes affect the surface texture of aesthetic dental restorative materials. Dental professionals may need to educate their patients to be cautious regarding the prolonged use of herbal toothpaste.
