Tin(II) Fluoride
Tin(II) Fluoride Uses, Dosage, Side Effects, Food Interaction and all others data.
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 . It manages and prevents dental caries and gingivitis by promoting enamel mineralization , reducing gingival inflammation and bleeding through its potential broad-spectrum antibiotic effect and modulation of the microbial composition of the dental biofilm . It is an FDA-approved over-the-counter product.
Tin(II) Fluoride mediates both bactericidal and bacteriostatic properties and provides an anti-erosive action on tooth enamel.

Uses
Tin(II) Fluoride is a medication used to treat dental hypersensitivity, produce enamel, prevent gingivitis and cavities, and prevent periodontal infections.
Indicated for use to relieve dental hypersensitivity, increase enamel production, prevent gingivitis and cavities, and control periodontal infections.
Tin(II) Fluoride is also used to associated treatment for these conditions: Dental Cavity
How Tin(II) Fluoride works
Tin(II) Fluoride has been shown to manage and prevent dental caries and gingivitis by promoting enamel mineralization, reducing gingival inflammation and bleeding, its potential broad-spectrum antibiotic effect, and through modulation of the microbial composition of the dental biofilm. It works by depositing a stable acid-resistant layer on the tooth surfaces which is composed of calcium fluoride produced when stannous fluoride converts the calcium mineral apatite into fluorapatite. Tin and fluoride mediate anti-erosive actions by interacting with and modifying the absorbent layer composed of salivary proteins such as mucins, perhaps by enhancing the cross-linking between the proteins to result in a more resistant and protective layer against erosion . The efficacy of stannous fluoride solutions seems to depend mainly on the incorporation of tin in the mineralized dentine when the organic portion is preserved but on surface precipitation when the organic portion is continuously digested. Moreover, the relative erosion-inhibiting effects of stannous fluoride strongly depend on the presence or absence of the demineralized organic dentine matrix .
Toxicity
The oral LD50 value in rats is 360mg/kg and the dermal LD50 value is >2000mg/kg. Repeated or prolonged dermal contact can cause irritant symptoms such as reddening of the skin, blisters, or dermatitis.
Food Interaction
No interactions found.Volume of Distribution
Tin(II) Fluoride is cleared from saliva rapidly but very well retained in gingival plaque for a prolonged period of time .
Elimination Route
Tin is retained in the demineralized organic matrix to some extent, diffuses through the phosphorylated non-collagenous proteins in the dentine called phosphophoryn and accumulates in the underlying mineralized tissue.
Half Life
The half-life for the decay of the salivary elimination rate constant was 13 min .
Clearance
Stimulated and nonstimulated salivary elimination microrate constants in this case would be ∼1 and 0.5 min^−1, respectively .
Elimination Route
Materials introduced into the oral cavity can be eliminated by salivary washout and swallowing, absorption through oral surfaces, or degradation .
