“…Similarly, in the study by Moretto et al [8], the use of fluoride toothpaste containing sodium fluoride showed a reduction in surface loss when compared to toothpastes without fluoride. This is probably due to the calcium fluoride layer formed on the enamel, which partially reduced wear in the erosion and abrasion cycles [23]. The fact that both toothpastes did not present significant differences when compared to the control group was not an expected result, and the authors relate this to the fact that children's toothpastes have lower abrasiveness and their pH is similar to that of water [23].…”

“…Of the twelve studies included in this review, eight used non-fluoride placebo toothpastes (experimental or commercial) as controls. The other studies [17,18,21,23] did not use toothpastes as a control group. However, all tested conventional fluoride toothpastes or non-fluoride toothpastes in the groups and that could allow some comparison, except for Wegehaupt et al [21].…”

“…The study by Passos et al [23] tested the effect of two toothpastes for kids, one non-fluoridated and one fluoridated (1100 ppmF NaF) in erosive-abrasive cycles in deciduous teeth. The two dentifrices presented similar results to the control group (abrasion with distilled water), but they were significantly different from each other, with the fluoride dentifrice showing less loss of enamel surface.…”

Objective: erosive tooth wear is a multifactorial condition that results in loss of dental hard tissue, caused by a chemical and mechanical process. This paper aims to carry out a systematic review presenting the effects of different toothpaste formulations on the loss of dental enamel surface in vitro. Material and Methods: the searches were performed in the databases PubMed, Web of Science, LILACS and Scielo. Articles published from 2010 to 2020 were filtered, without language restriction. Articles that included abrasion and erosion protocols were searched, as they were more similar to clinical reality, since toothpaste is applied through tooth brushing. The searches with descriptors and free terms on the topic resulted in 992 articles, however only 12 were within the search criteria. Results: the selected studies appointed that association of conventional fluorides (NaF) with metallic fluorides can be a promising strategy for the reduction of surface loss by erosive tooth wear. Toothpastes containing sodium fluoride, as well as tin without chitosan, showed a reduction in surface loss, considered sufficient for individuals with medium exposure to acids. In children's toothpastes, the one containing sodium fluoride showed a reduction in surface loss when compared to non-fluoride dentifrices. Conclusion: different protocols may result in less or greater loss of enamel surface, and methodological differences should be considered. To clarify the effects of dentifrices on erosive tooth wear, other properties of dentifrices should be investigated.

The relative dentin abrasivity-profilometry equivalent values were compared using non-contact profilometry with three subtypes of regular toothpaste and two subtypes of whitening toothpaste containing sodium bicarbonate and 35% hydrogen peroxide. Bovine dentin specimens were assigned to six groups: regular toothpaste (R): R1 (BAMBOO SALT GUM OINTMENT); R2 (MEDIAN TARTAR ORIGINAL); R3 (PERIOE Alpha), Reference slurry: RS (calcium pyrophosphate), whitening toothpaste (W): W1 (NET. WT); W2 (Vussen 28 WHITENING). Relative dentin abrasion-profilometry equivalent (RDA-PE) was determined by brushing 10,000 times (n=8). The pH of the toothpaste was measured (n=5) and the abrasive constituents of the toothpaste was analyzed by FE-SEM and EDS. The RDA-PE values ranged from 26 to166, and the pH level ranges were 4.928-9.153. The RDA-PE value of the whitening toothpaste containing hydrogen peroxide was not high compared with that of the regular toothpaste. The RDA-PE values of whitening toothpaste could vary depending on the mechanism and ingredients of the whitening agents.

“…Previous studies have shown that primary dental hard tissues might be more prone to erosion [2] and erosive tooth wear than permanent enamel and dentin [3][4][5]. However, while the effect of toothbrushing on the development of erosive tooth wear has been intensively studied on permanent teeth [6], information on the interaction of toothbrushing and erosion on primary teeth is hardly available [3,7].…”

This in-vitro study aimed to analyse the effect of brushing and different brushing parameters (kind of toothpaste, kind of toothbrush, brushing force) on erosive tooth wear of primary bovine enamel and dentin. Specimens were prepared from primary bovine enamel or dentin (each group n = 12) and cyclically eroded (6 × 60 s/d, citric acid, pH 2.4) and brushed with children’s toothbrushes (2 × 15 s/d) over 5 days. The brushing parameters under investigation were: toothpaste (fluoridated, fluoride-free), toothbrush (manual; rotating-oscillating and sonic, each at two different activation modes) and brushing force (1 N, 2 N). Specimens that were only eroded and not brushed served as controls. Enamel and dentin wear was quantified using widefield confocal microscopy. Statistical analysis was performed using three- and one-way ANOVAs followed by Scheffe’s (enamel) or Tamhane’s (dentin) post-hoc tests (p < 0.05). Brushing with the fluoridated toothpaste was able to significantly reduce erosive wear in enamel (by 15 to 37%, 6 of 10 groups) and in dentin (by 58 to 72%, all groups), while brushing with the fluoride-free toothpaste was not different from the controls. Considering the kind of toothpaste and brushing force, slight differences between the toothbrushes were observed in enamel, but not in dentin. Within the same toothbrush and activation mode, almost no differences between 1 and 2 N brushing force were detected. In conclusion, erosive tooth wear on primary bovine dental hard tissue mainly depends on the kind of toothpaste, rather than on the kind of toothbrush and the brushing force.
