Which characteristic is NOT true about glass ionomers?

Glass ionomer cements are known for several key characteristics that make them valuable in dentistry. One of their most notable traits is the ability to chemically bond to dentin, which enhances retention and reduces the risk of microleakage at the margins of restorations. This chemical bonding occurs due to the interaction between the acidic components of glass ionomers and the calcium in the tooth structure.

Another important feature of glass ionomers is their ability to release fluoride, which contributes to caries prevention around the restoration area. The fluoride release is beneficial as it helps in remineralizing adjacent tooth structure and provides ongoing protection.

Glass ionomers can be utilized in various clinical applications, including as cements, bases, liners, and even permanent restorations in specific situations, making them versatile materials in restorative dentistry.

However, when it comes to being unaffected by moisture during the placement of these materials, this is not true. Glass ionomers are sensitive to moisture, and their properties can be compromised if they are placed in a moist environment. For optimal results, it is critical to manage moisture control effectively when working with glass ionomers, ensuring that the surface is dry and free from contaminants during application.

Thus, the statement regarding glass ionomers being unaffected by moisture when placing
