KöR Desensitizer helps desensitize and prevent sensitivity issues immediately, before they arise.
Our desensitizing method includes desensitizers that plug the orifices of dentinal tubules during bleaching to “prevent” bleaching sensitivity, rather than simply attempting to treat the symptoms. The “Hydrodynamic Mechanism” theory of tooth sensitivity states that movement of the fluid within dentinal tubules is responsible for mechanically activating the nerves at the periphery of the pulp, causing a painful reaction. When the natural smear plugs are lost from the orifices of dentinal tubules, fluid within the tubules can move thirty-two times more freely, causing dentinal hypersensitivity.
The oxygenation process during bleaching not only deeply cleanses the tooth, but also actively displaces the plugs in dentinal tubules, leaving the tubular fluid susceptible to flow. The bleaching chemicals create an osmotic gradient in fluid flow within the dentinal tubules outward from the pulp. The result is typical bleaching sensitivity, which can sometimes be very acute.
Potassium nitrate, often recommended for treatment of sensitivity, does not plug tubules. In some patients it partially reduces the ability of the pulpal nerves to fire. This affect does not eliminate the pulpal inflammation, and only partially masks the symptoms. Some claim ACP will block dentinal tubules, however ACP has been primarily developed and studied in relation to repairing highly inorganic enamel, not the more organic dentin. Even if ACP were to cause mineral formation within dentin, which is much more organic in nature than enamel, it would do so by slowly “growing” tooth structure instead of actively and rapidly “plugging” tubules. KöR desensitizers actively and rapidly plug and re-plug the orifices of the dentinal tubules during bleaching to “prevent” pulpal inflammation and sensitivity rather than simply treat the symptoms. The first desensitizer, applied at chairside, plugs tubules. The second desensitizer, applied by the patient daily at home, also plugs tubules via HEMA binding with intratubular proteins as well as precipitation of calcium fluoride within tubules.
