One hundred samples were pre-eroded (0.3% citric acid, pH 2.6, 10 min) and randomized into five groups (n=10 for each substrate): Negative control - milli-Q water; NaF-free - Experimental varnish SnCl\u2082-free and NaF-free; 2.5 NaF - Experimental varnish 5% SnCl\u2082 associated with 2.5% NaF; 5.2 NaF: Experimental varnish 5% SnCl\u2082 associated with 5.2% NaF and positive control - Commercial varnish containing 5% NaF (Duraphat). After the varnishes were applied, the erosive and abrasive challenges were carried out for five days. Loss of tooth structure (TSL) was determined by optical profilometry, and the loss of calcium (\u0394Ca2+) using atomic absorption spectroscopy. Dentin analysis was also performed by SEM. A one-way ANOVA\/Bonferroni test was performed to analyze the data (\u03b1=0.05). The experimental 2.5 NaF and 5.2 NaF groups showed greater effectiveness in preventing TSL when compared to the other groups (p &lt;0.05), regardless of the substrate. In addition, these groups showed lower loss in Ca2+ content when compared to the other groups (p &lt;0.05), for enamel and dentin. Dentin showed greater TSL and \u0394Ca2+ loss when compared to enamel in all treatments (p &lt;0.05). The 5.2% and 2.5% NaF-containing experimental varnishes showed promising results in both, the prevention of TSL and the loss of Ca2+, regardless of the substrate studied.<\/jats:p>","DOI":"10.1590\/0103-6440202203969","type":"journal-article","created":{"date-parts":[[2022,3,7]],"date-time":"2022-03-07T12:03:51Z","timestamp":1646654631000},"page":"68-76","source":"Crossref","is-referenced-by-count":9,"title":["Anti-erosive profile of an experimental 5% SnCl\u2082 varnish containing different concentrations of NaF"],"prefix":"10.1590","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0694-6863","authenticated-orcid":false,"given":"Cristiane de Melo","family":"Alencar","sequence":"first","affiliation":[{"name":"Universidade Estadual Paulista,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9258-2508","authenticated-orcid":false,"given":"Mara Eliane Soares","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Universidade Federal do Par\u00e1,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0172-9891","authenticated-orcid":false,"given":"Joissi Ferrari","family":"Zaniboni","sequence":"additional","affiliation":[{"name":"Universidade Estadual Paulista,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2322-8158","authenticated-orcid":false,"given":"Thais Piragine","family":"Leandrin","sequence":"additional","affiliation":[{"name":"Universidade Estadual Paulista,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9437-0445","authenticated-orcid":false,"given":"Aryvelto Miranda","family":"Silva","sequence":"additional","affiliation":[{"name":"Universidade Estadual Paulista,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9120-4305","authenticated-orcid":false,"given":"Edson Alves de","family":"Campos","sequence":"additional","affiliation":[{"name":"Universidade Estadual Paulista,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2022,2]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"91","DOI":"10.1159\/000455376","article-title":"Chapter 9: Acidic Beverages and Foods Associated with Dental Erosion and Erosive Tooth Wear","volume":"28","author":"Carvalho TS","year":"2020","journal-title":"Monogr Oral Sci"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1159\/000503308","article-title":"Terminology of Erosive Tooth Wear: Consensus Report of a Workshop Organized by the ORCA and the Cariology Research Group of the IADR","volume":"54","author":"Schlueter N","year":"2020","journal-title":"Caries Res"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"1557","DOI":"10.1007\/s00784-015-1511-7","article-title":"Consensus report of the European Federation of Conservative Dentistry: erosive tooth wear -
