Analysis of the Surface Morphology of Dental Enamel Exposed to Ready-to-Drink Alcoholic Beverages. [PDF]

Int J Dent
Background Ready‐to‐drink (RTD) alcoholic beverages often contain organic acids that lower pH and promote enamel demineralization, yet their erosive potential remains insufficiently explored. Objective This study aimed to evaluate the erosive potential of RTDs through chemical characterization and analysis of enamel surface alterations.
