This phenomenon is primarily caused by acids present in the mouth through the intake of acidic foods or beverages, the production of acids by bacteria present in the mouth, or the regurgitation of stomach acids. Demineralization exposes the dentinal tubules allowing access to dental nerves. It also weakens the hard surfaces of the teeth, increasing the incidence of dental caries. To combat this problem, Drs. Sereda and Brower have developed a technique that decreases dental sensi...</description><pubDate>Wed, 28 Feb 2018 09:37:23 GMT</pubDate><author>Binnie.Goodwin@usd.edu</author><guid>http://usd.technologypublisher.com/tech/Sequential_Material_Deposition_for_Remineralization_and_Desensitization_of_Teeth</guid></item></channel></rss>
