Pages 119-122, Language: EnglishErdoganEndemic dental fluorosis is a form of enamel hypoplasia characterized by moderate-to-severe staining of the tooth surface. Since 1916, numberous investigators have used hydrochloric acid alone on fluorosis stains. More recently, 18% hydrochloric acid-pumice microabrasion has been used to achieve color modification. The main disadvantage of this procedure is the high concentration and low viscosity of hydrochloric acid, which can cause damage to oral and dental tissues. To eliminate this problem, quartz particles can be mixed with the hydrochloric acid. The quartz particles prevent teh hydrochloric acid from flowing uncontrollably by altering it to a gel-like form. A modified 18% hydrochloric acid-quartz-pumice abrasion technique was used to remove fluorine stains from vital teeth in a teenager.
