What is one notable property of glass ionomer materials?

• A. They can only be used in anterior restorations
• B. They require etching for adhesion to tooth structures
• C. They chemically bond to enamel, dentine, and cementum
• D. They are only light-cured

Answer: (C)

One notable property of glass ionomer materials is their ability to chemically bond to enamel, dentine, and cementum. This characteristic makes them particularly useful in restorative dentistry, as they provide a strong bond to the tooth structures without the need for additional bonding agents, which can be a requirement for other types of dental materials. This chemical bonding occurs through the formation of ionic bonds, which not only contributes to the stability of the restoration but also helps in the release of fluoride over time, promoting further remineralization and protection of the tooth. This property is especially valuable in vulnerable areas of the dental structure, making glass ionomer materials suitable for various applications beyond just anterior restorations.
