THE EFFECTIVENESS OF A MODIFIED HYDROCHLORIC ACID-QUARTZ-PUMICE ABRASION TECHNIQUE ON FLUOROSIS STAINS - A CASE-REPORT

Endemic dental fluorosis is a form of enamel hypoplasia characterized by moderate-to-severe staining of the tooth surface. Since 1916, numer ous investigators have used hydrochloric acid alone on fluorosis stain s. More recently, 18% hydrochloric acid-pumice microabrasion has been used to achieve color modification. The main disadvantage of this proc edure 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 the hydrochloric acid from flowing uncontrol lably by altering it to a gel-like form. A modified 18% hydrochloric a cid-quartz-pumice abrasion technique was risen to remove fluorine stai ns from vital teeth in a teenager.
