Resin-modified glass ionomer is a type of dental material that combines the properties of traditional glass ionomer cement with added resins. This modification enhances its strength, wear resistance, and aesthetic qualities, making it suitable for various dental applications, including fillings and restorations. The material releases fluoride, which helps in preventing tooth decay, and bonds well to both tooth structure and metal surfaces. Its versatility allows it to be used in both anterior and posterior teeth, providing a reliable option for dentists in restorative procedures.
