Which of the following is false about glass ionomer cement?
Correct Answer: Poor marginal seal
Description: The adhesion of GIC to dentin reduces the probability of gap formation at gingival margins located in dentin or cementum, compensating for the polymerization shrinkage of the overlying resin-based composite restoration on the hybrid ionomer base.
