Dental erosion is a common problem in dentistry, and it refers to the chronic pathological loss of dental hard tissues due to nonbacterially produced acids, primarily caused by the exposure of teeth to exogenous acids. Dietary factors play a pivotal part in the pathogenesis of dental erosion, with a high intake of acidic beverages leading to an increased prevalence of dental erosion in adolescents. Fluoride is mainly used in clinical practice to prevent dental erosion. However, long-term fluoride intake may lead to chronic fluorosis symptoms caused by fluoride overdose. Nano-coatings on dental surfaces have become a popular area of research in dental materials in recent years. The objective of this study was to develop a novel nerol-segmented waterborne polyurethane nano-coating to protect teeth from direct contact with an acidic environment and to provide a safe, effective method for preventing dental acid erosion.
