What happens to glass ionomer cements compared to resin-based cements in compressive strength?

The correct answer highlights that glass ionomer cements typically exceed the compressive strength of resin-based cements. Glass ionomer cements are known for their ability to bond chemically to both enamel and dentin, providing a stable foundation for clinical use. This strong chemical interaction contributes to the higher compressive strength observed in these materials, making them particularly suitable for areas requiring durability under load.

Furthermore, glass ionomer cements have the added benefit of releasing fluoride, which can contribute to the remineralization of adjacent tooth structures, ultimately enhancing the overall strength and longevity of restorative work. In contrast, resin-based cements, while commonly used due to their aesthetic qualities and excellent bonding capabilities, do not typically achieve the same compressive strength as glass ionomer cements.

Consequently, when comparing the two under clinical conditions, glass ionomer cements demonstrate superior performance in terms of compressive strength, reaffirming their effectiveness in certain dental applications.
