Using the hydrodynamic theory, the potassium ions (K+) from the potassium nitrate act directly on the nerves by blocking the action potential generated in intradental Many of the leading sensitive toothpastes contain 5% potassium nitrate in their formulation. This amount is enough to help relieve sensitivity as well. The conscious thesely practice runs from 350-1275 mg in child to 1875 and 5625 mg in each gender. Potassium nitrate is soluble in hot water.

The mean value of the VAS score prior to the use of the toothpaste was 50.72, while the mean value of the VAS score after use was 30.68. Potassium ions are thought to act by blocking the action potential generated in intradental nerves. Four studies were included in the meta-analysis which showed statistically significant effect of potassium nitrate toothpaste on air blast and tactile sensitivity, e.g. in a dentifrice or gel to alleviate dentinal hypersensitivity. It provides increasing protection against painful sensitivity of the teeth to cold, heat, acids, sweets or contact 13, 14. Potassium ions are thought to act by block- ing synapses between nerve cells, thereby reducing nerve excitation and the associated pain. 24,25 Several clinical studies demonstrated that tooth- pastes containing potassium ions provide effective Efficacy of desensitizing toothpaste 177 desensitization. Tooth hypersensitivity can be relieved by inactivating the intra-dental nerve and inhibiting neural transmission, using suitable medications. The purported mechanism of action of these treatments is either occlusion of dentin tubules (e.g. This article discusses the use of a dye penetration technique, which establishes this mechanism of action for a desensitizing fluoride toothpaste containing calcium and phosphate. Subjects not using the same brand of toothpaste for at least 4 months prior to the screening visit; Simply put (summing up the points above), potassium nitrate helps to desensitize the nerves inside of your teeth and stannous fluoride helps to create a barrier over sensitive areas. It is used to relieve tooth sensitivity to cold, heat, acids, sweets or contact. Potassium nitrate calms the tooth's nerve activity so that you feel less discomfort when eating hot, cold, sweet or sticky foods. The use of Colgate Sensitive Multi Protection was found to. Colgate Sensitive Maximum Strength Whitening Toothpaste provides 24/7 sensitivity protection and contains potassium nitrate, the FDA-allowed antisensitivity active ingredient. It is an alkali metal nitrate because it is an ionic salt of potassium ions K + ions and nitrate ions NO 3. Potassium Nitrate is Frequently Found in Sensodyne Although many toothpaste brands utilize potassium nitrate, it is most commonly used in Sensodyne. Potassium nitrate contains potassium (a soft, light, and silver metal), oxygen, and nitrogen (a colourless and odourless gas). In each study the toothpastes compared will either both contain fluoride or have no fluoride. Potassium nitrate has been used . An insolubles-free test toothpaste, similar to AHECS, but without the insoluble silica thickener and titanium dioxide ingredients (IF). Potassium ions are dreamed to hurt the synapse between nerve mobile phones, that is why lesseneding nerve excitation and the tied in with distress 10 . When used in toothpaste, potassium nitrate makes up just 5% of the total ingredient content. Mechanism of Action of Potassium Nitrate Potassium nitrate is used as a desensitizing agent. An insolubles-free control, similar to the insolubles-free test toothpaste but without the calcium sulfate and dipotassium phosphate ingredients (C2). In the United Kingdom, the conscious practice is 3.5 g/day for organic each gender 7 . Potassium Nitrate vs. Potassium Fluoride Here's how desensitizing toothpaste works: Desensitizing toothpastes contain some active agents, such as potassium, fluorides, and strontium salts 3. Sensodyne formulations with potassium nitrate provide daily sensitivity protection* Formulations with potassium nitrate build soothing protection by desensitizing the nerve inside the tooth. 3.1.4. *with twice daily brushing SM7677 USA Senso KNO3 MOA 2 Watch on resins, varnishes, .

Good choice Colgate Sensitive Prevent & Repair Toothpaste With Whitening One method of treating hypersensitivity is to occlude the tubules, preventing fluid movement. the meta analysis of air blast sensitivity showed a standardized mean difference in sensitivity score of -1.51 (95% CI: -2.09 to -0.94) in favour of treatment. Condition or disease Intervention/treatment Phase ; . 1-6 Relief starts within two weeks and continues to build with twice daily brushing. Whitening toothpastes that contain potassium nitrate both remove surface stains and help prevent sensitivity. Potassium nitrate is a salt compound and a natural desensitizing agent. Mechanism: Potassium ions are believed to disturb the synapse between nerve cells, thus decreasing nerve excitation and the associated pain. This review focused on studies that incorporated similar methods in order to determine if KNO 3 is an effective agent in reducing . Types of Outcome Measures Potassium nitrate and sodium fluoride are widely used to protect from tooth sensitivity 4. Dentin had a 118% permeability when treated with the arginine-and-calcium carbonate. potassium ions in sensitive toothpastes would enable dental patients select the appropriate and effective paste to successfully treat tooth sensitivity. The method is applicable to analysis of pharmaceutical preparations. Applying potassium nitrate caused the dentin to display a permeability of 87%, while the arginine-and-calcium carbonate toothpaste blocked the dentin tubules the least.
