Evaluation of Low-shrinkage Giomer Versus Resin-Modified Glass Ionomer in Cervical Caries Lesions: A Clinical Trial

Low shrinkage giomer resin composite shows both sustained fluoride release and recharge, and low volumetric shrinkage of less than 1% with low resultant polymerization shrinkage stress. Such remarkable feature is due to the novel SRS (Steric Repulsion Structured) molecule which is designed to decrease polymerization shrinkage through molecular steric repulsion resulting in a stable restoration microstructure (AlQranei MS et al, 2021). Thus, low shrinkage giomers are best indicated in class V cavities where the dentin bonding agent does not have high strength (Algailani U, et al 2022).
