What is the main benefit of using glass ionomer cement in dental restorations?

The main benefit of using glass ionomer cement in dental restorations lies in its versatility and adhesive properties. Glass ionomer cement bonds chemically to both enamel and dentin, making it an excellent material for various dental applications, such as fillings and luting agents. This chemical adhesion not only provides a stronger bond compared to other materials but also allows for the release of fluoride, which can help in preventing secondary caries.

Additionally, glass ionomer is useful in situations where moisture control is challenging, as it can set in the presence of saliva. This makes it a preferred choice in specific dental procedures where other materials might not perform as well. The combination of these adhesive properties and versatility across different types of restorations is what primarily sets glass ionomer cement apart in the dental field.

While factors such as cost-effectiveness, high strength, and ease of application are important considerations, they do not capture the primary advantage that glass ionomer cement provides in terms of its unique bonding capabilities and functional benefits in restorative dentistry.
