Then in 1994, a study showed that APF also pitted resin-veneering material.
In 1981, researchers proved that APF caused pitting in composite resin restorations.
Stannous fluoride 0.45% (0.16% w/v fluoride ion) Purpose. BACKGROUND OF CHLORHEXIDINE AND FLUORIDE. Stannous fluoride formulation accelerates occlusion of exposed dentine tubules.
There is limited information regarding Stannous fluoride Contraindications in the drug label.
million (ppm) fluoride ion, and 2 percent sodium fluoride (NaF), which contain 0.90 percent or 9,050 ppm fluoride ion. 3 They work via different mechanisms; the potassium ions in potassium nitrate help to reduce sensitivity by depolarizing the nerve cells 4 while stannous fluoride acts to reduce sensitivity by occluding the dentinal tubules with a tin-rich surface deposit.
Stannous fluoride is an anticavity, antigingivitis, antihypersensitivity mouthrinse that is FDA approved for the prophylaxis of dental decay. However, there are few clin- TOPICAL FLUORIDES USED IN PREVENTIVE DENTISTRY: 1.SODIUM FLUORIDE: 2.STANNOUS FLUORIDE 3.ACIDULATED PHOSPHATE FLUORIDE 4.AMINE FLUORIDE 1) NEUTRAL SODIUM FLUORIDE Fluoride concentration - 9200ppm A minimum of four applications with a 2% NaF solution gives a caries reduction of about 30% METHOD OF PREPARATION It is prepared by dissolving 20 … Note: the %w/v fluoride ion of this product is 0.19. Fluoride-containing var-nishes typically contain 5 percent NaF, which is equivalent to 2.26 percent or 22,600 ppm fluoride ion.
The difference between stannous fluoride and sodium fluoride is that only the first kills bacteria while both have been shown to rebuild enamel. Anticavity/Sensitivity Relief/Antigingivitis. ... Contraindications. 1/17/2005 In the 1950s, the Holy Grail of toothpaste was to create a product with therapeutic as well as cosmetic benefits. Chlorhexidine is an antimicrobial and a cationic bisbiguanide that in its active form has the unique ability to be adsorbed to oral tissues such as hydroxyapatite, tooth surfaces, oral mucosa and salivary mucins for extended periods of time, and then be released later when its concentration in the oral cavity is reduced.24,25 This extended … Stannous fluoride’s inhibitory effect on bacteria is related to its inhibition of bacterial glycolysis, an energy making process whereby metabolic enzymes break down carbohydrates. Warnings. Priority will be given to letters less than 500 words long. Nevertheless, both these fluorides when used in oral care products help strengthen and repair enamel that is weakened by acids, preventing decay. Because of the concern about etching of composite and porcelain restorations with the constant use of APF (pH 3.0) and stannous fluoride (pH 2.1 to 2.3), these are usually replaced with neutral pH sodium fluoride.
