Stannous fluoride; prevention; removal; stabilized; stain. [16], SnF2 is a reducing agent, with a standard reduction potential of Eo (SnIV/ SnII) = +0.15 V.[17] Solutions in HF are readily oxidised by a range of oxidizing agents (O2, SO2 or F2) to form the mixed-valence compound Sn3F8 (containing SnII and SnIV and no Sn–Sn bonds). Find NCBI SARS-CoV-2 literature, sequence, and clinical content: [22], Except where otherwise noted, data are given for materials in their, The majority of toothpastes contain calcium minerals, CS1 maint: multiple names: authors list (, Egon Wiberg, Arnold Frederick Holleman (2001), "National Inventors Hall of Fame Announces 2019 Inductees at CES", "Topical applications of sodium fluoride and stannous fluoride",, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Articles with unsourced statements from February 2019, Creative Commons Attribution-ShareAlike License, This page was last edited on 12 October 2020, at 01:23. [13] In solutions containing the fluoride ion, F−, it forms the fluoride complexes SnF3−, Sn2F5−, and SnF2(OH2). 2019 Dec 9;5(12):e02850. Conclusions: [14] Complexes of SnF2, sometimes called difluorostannylene, with an alkyne and aromatic compounds deposited in an argon matrix at 12 K have been reported. [18] Other forms reported have the GeF2 and paratellurite structures. A stain removal clinical study was conducted as a randomized, double-blind, 2-cell, parallel-group design using Colgate TotalSF and nonwhitening regular fluoride toothpaste. Your dentist can polish this off easily. At acute levels (over 2 mg/m3), if ingested, it can cause abdominal pains and shock. Reduce bacteria in the mouth: Stannous fluoride contains strong antibacterial properties that help reduce the bacteria in the mouth. [19][20], Stannous fluoride can cause redness and irritation if it is inhaled or comes into contact with the eyes. 2010 Mar;103(3):163-9. doi: 10.1016/S0022-3913(10)60023-6. Crest goes beyond the brush for clinically proven healthy gums. Current formulations of stannous fluoride are much more stable than they used to be, and don’t cause any real staining. Published by Elsevier Inc. All rights reserved. No adverse effects were reported. 2020 Dec;70(6):418-426. doi: 10.1111/idj.12588. NaSn2F5 or Na4Sn3F10 depending on the reaction conditions, rather than NaSnF3. In recognition for their innovation, these two individuals were inducted into the Inventor's Hall of Fame. HHS Clipboard, Search History, and several other advanced features are temporarily unavailable. Clinical study to compare extrinsic stain formation in subjects using three dentifrice formulations. In an in vitro stain prevention study, Colgate TotalSF performed 26% and 35% better than a competitor paste and nonabrasive SnF2 gel, respectively. It was introduced for this purpose by Joseph Muhler and William Nebergall. The biggest concern with using stannous fluoride was that it stained your teeth. Johannsen A, Emilson CG, Johannsen G, Konradsson K, Lingström P, Ramberg P. Heliyon. 2000;(27):23-7; quiz 28. The NaF caused le … In vitro staining effects of stannous fluoride and sodium fluoride on ceramic material J Prosthet Dent. This used to be more of a problem in the past. Sharma N, Galustians J, Qaquish J, Rustogi KN, Petrone ME, Chaknis P, DeVizio W, Volpe AR, Proskin HM. Background: It also used to have an unpleasant taste and leave a gritty feeling in your mouth. Methods: Background: This article highlights a stabilized stannous fluoride (SnF 2) dentifrice that, in addition to being efficacious against caries, gingivitis, and dentin hypersensitivity, demonstrates high-performing stain prevention and removal efficacy. [18], In the vapour phase, SnF2 forms monomers, dimers, and trimers. Get the latest public health information from CDC: [14] Monomeric SnF2 is a non-linear molecule with an Sn−F bond length of 206 pm. Stannous Fluoride is antibacterial, that is why it is used. Fiorillo L, Cervino G, Herford AS, Laino L, Cicciù M. Biomimetics (Basel). [8] The compound NaSnF3, containing the pyramidal SnF3− anion, can be produced from a pyridine–water solution. When used in dental products, mild tooth discoloration may also occur; this can be removed by brushing. In a clinical study, Colgate TotalSF use showed statistically significant extrinsic tooth stain reductions by 17.5% (3 weeks) and 27.8% (6 weeks) relative to regular fluoride toothpaste. The results indicate that the stabilized Colgate TotalSF performed statistically better than other SnF2 pastes in an in vitro study, and statistically better than a regular fluoride toothpaste in a clinical study. New toothpastes that contain stannous fluoride, such as crest pro health have addition ingredients that prevent this staining. [21] Rare but serious allergic reactions are possible; symptoms include itching, swelling, and difficulty breathing. Stannous fluoride was introduced as an alternative to sodium fluoride for the prevention of cavities. Conforti N, Mankodi S, Zhang YP, Chaknis P, Petrone ME, DeVizio W, Volpe AR. Comparison of new formulas of stannous fluoride toothpastes with other commercially available fluoridated toothpastes: A systematic review and meta-analysis of randomised controlled trials. Stannous Fluoride, or Tn(II) Fluoride, is a compound commonly used in toothpastes for the prevention of gingivitis, dental infections, cavities, and to relieve dental hypersensitivity.Although similar in function and activity to Sodium Fluoride (NaF), the conventionally added ingredient in toothpastes, stannous fluoride has been shown to be more effective at stopping and reversing dental lesions. Moreover, since acids in the mouth are usually produced by bacteria, using a stannous fluoride product helps decrease the production … Colgate TotalSF offers an SnF2-based therapeutic dentifrice with notable performance in stain prevention and removal. Effects of stabilized stannous fluoride dentifrice on dental calculus, dental plaque, gingivitis, halitosis and stain: A systematic review. A six-week clinical efficacy study of three commercially available dentifrices for the removal of extrinsic tooth stain.

Epub 2020 Jul 4. COVID-19 is an emerging, rapidly evolving situation.  |  In each case, there are three nearest neighbours, with Sn at the apex of a trigonal pyramid, and the lone pair of electrons sterically active. [15] Other compounds containing the pyramidal SnF3− anion are known, such as Ca(SnF3)2.
