The full range of research studies can be accessed on the Colgate Dental Professional Web site ( ). Laboratory tests demonstrating the product’s mode of action, as well as clinical trials demonstrating relief of dentin hypersensitivity immediately and 4 weeks after a single application have been presented as evidence that the Pro-Argi technology provides instant and lasting relief of dentin hypersensitivity. This plug, which is resistant to normal pulpal pressures and to acid challenge, effectively reduces dentin fluid flow, and thereby reduces sensitivity. Mechanism of action studies have shown that this technology physically seals dentin tubules with a plug that contains arginine, calcium, and phosphate. These ingredients are delivered in a paste containing a mild abrasive system, and can be applied with a prophylaxis cup or a cotton-tipped applicator to teeth that exhibit dentin hypersensitivity. The Pro-Argin™ technology consists of arginine, a naturally occurring amino acid, and an insoluble calcium compound, in the form of calcium carbonate. In 2009, the Colgate-Palmolive Company introduced a new in-office treatment for dentin hypersensitivity called Colgate ® Sensitive Pro-Relief™ desensitizing paste ( Figure 1), based on the Pro-Argin technology. Pro-Argin™ Technology Treats Hypersensitivity
In addition, use of the product often needs to be continued to maintain the relief afforded by the potassium ions/salts. Most products require continued use over a 4- to 8-week period before significant relief may be realized. The potassium ions must pass from the external dentin surface, through the dentin tubule to the pulp to reduce the excitation caused by fluid movement in the dentin tubules, and block the transmission of the stimulus from the odontoblastic process to the nerve in the pulp chamber. The most commonly used agent is potassium nitrate, usually delivered in a dentifrice that is applied daily by the patient during regular toothbrushing. These agents can be applied professionally in the office or by the patient using home-care products.ĭesensitizing agents work by altering the levels of charged molecules in the dentin fluid. This might be considered a more “natural” treatment process, in a sense re-creating the missing cementum layer that previously covered the dentin tubules. Occluding agents act by physically covering or “plugging” the open, exposed dentin tubules, preventing the effect of thermal changes or physical stimuli caused by the movement of dentin fluid due to pressure changes. This has resulted in the development of two major classes of products-agents that occlude dentin tubules and desensitizing agents that interfere with the transmission of nerve impulses. The treatment and prevention of dentin hypersensitivity has focused on eliminating the ability of the causative agent to stimulate discomfort. The external stimulus is usually transitory, and the discomfort subsides shortly after the stimulus is removed.
An external stimulus, such as a change in external temperature, air movement, or physical stimulus, can cause the patient discomfort. Then, an appropriate treatment plan to address the problem can be implemented.Īs a result of any number of factors, including abrasion or periodontal disease causing gingival recession, or erosion removing the surface of tooth enamel, the underlying dentin and dentin tubules can become exposed. The dental professional often needs to perform a thorough examination, as well as additional tests, to determine why the pain is occurring and to rule out other possible causes of the pain (periodontal disease, caries, etc). The cause and description of the pain reported by the patient can vary and is often not adequate to make a definitive diagnosis. The diagnosis of dentin hypersensitivity often poses a challenge for the dental professional.
