Resumo

Aim: The objective of this research was to compare the abrasive potential of dentifrices containing activated charcoal with those of a conventional dentifrice on the development of erosive tooth wear (ETW) in vitro. Methods: Enamel and dentin samples were divided into toothpastes (n = 12): group (G)1 -Colgate Triple Action (1450 ppm F) (positive control); G2-Colgate Natural Extracts (1450 ppm F); G3-Colgate Luminous White Activated Carbon (1450 ppm F); G4-Oral-B Whitening Therapy Charcoal (1100 ppm F); G5-Oral-B 3D White Mineral Clean (1100 ppm F); G6-Curaprox Black Is White (950 ppm F); and G7-erosion only (no abrasion, negative control). All samples were submitted to erosive pH cycles and G1 to G6 to abrasive chal-lenges (15 seconds) using toothpastes' slurries plus 45 seconds of treatment for 7 days. The final profile was overlaid to the baseline one for the ETW calculation (& mu;m). The data were subjected to analysis of variance/Tukey or Kruskal-Wallis/Dunn tests (P < .05). Results: Oral-B 3D White (13.0 & PLUSMN; 1.0, 9.37 [1.36] & mu;m), Oral-B Whitening Therapy (15.1 & PLUSMN; 1.2, 8.58 [1.71] & mu;m), and Colgate Luminous White (13.6 & PLUSMN; 1.0, 7.46 [0.94] & mu;m) toothpastes promoted the greatest enamel and dentin wear. On the other hand, Colgate Triple Action (12.2 & PLUSMN; 1.2, 5.30 [1.26] & mu;m), Colgate Natural Extracts (10.8 & PLUSMN; 1.1, 4.16 [1.11] & mu;m), and Cura-prox Black Is White (11.5 & PLUSMN; 1.5, 4.06 [0.92] & mu;m) toothpastes promoted lower wear values, similar to erosion only (4.16 [0.94] & mu;m) in the case of dentin but not enamel (7.1 & PLUSMN; 0.8 & mu;m). Conclusions: Toothpastes containing charcoal combined with pyrophosphate may have a high abrasive effect on eroded tooth surfaces. Many patients influenced by digital market-ing use toothpastes containing activated charcoal with the aim of bleaching their teeth. However, care should be taken when using these products, as they may have a high abra-sive effect. & COPY; 2022 The Authors. Published by Elsevier Inc. on behalf of FDI World Dental Federation.
