Which statement is false regarding the compressive strength of glass ionomer cements?

The assertion that the compressive strength of glass ionomer cements is lower than that of traditional cements is accurate in the context of dental materials, particularly when comparing glass ionomer to other categories like resin-based cements. Traditional cements, such as zinc phosphate and other resin-based materials, generally exhibit higher compressive strength.

Glass ionomer cements have unique properties that make them suitable for specific clinical situations, such as their chemical bonding to tooth structure and release of fluoride, but they typically do not reach the compressive strength levels seen in many traditional cement types. This characteristic is important for clinicians to consider when choosing materials for specific applications, especially in load-bearing situations where strength is a critical factor.

The other statements regarding glass ionomer cements reflect their advantages or strengths. For instance, they may demonstrate a higher compressive strength compared to some other cement types, a 24-hour compressive strength advantage due to rapid setting reactions, and notable longevity in performance under certain conditions due to their adhesive properties and fluoride release. Understanding these aspects guides dental professionals in making informed material choices in practice.
