The World Health Organization (WHO) has added glass ionomer cement (GIC) to the WHO Model List of Essential Medicines since 2021, which represents the most efficacious, safe and cost-effective medicines for priority conditions. With the potential increase in the use of GIC, this review aims to provide an overview of the clinical application of GIC with updated evidence in restorative and preventive dentistry. GIC is a versatile dental material that has a wide range of clinical applications, particularly in restorative and preventive dentistry. It has unique properties, such as direct adhesion to tooth structures, minimal shrinkage or expansion, a similar coefficient of thermal expansion to natural tooth structure, biocompatibility, and long-lasting fluoride release. According to the chemical composition, GIC can be classified as conventional glass ionomer cement (CGIC) and resin-modified glass ionomer cement (RMGIC). It has been used as restorative materials, luting cement for indirect restorations, liner and base of restorations, and dental sealants. While its use as a base material and liner is debatable, the clinical application of GIC as restorative cement, luting cement, and dental sealant is supported by current research.

Measurement of Fluoride Ion Release From Restorative Material Using an Ion-Selective Electrode and Ultraviolet-Visible Light Spectrophotometer.

J Int Soc Prev Community Dent

December 2024

Department of Environmental Science, School of Life Sciences, Mysuru, JSS Academy of Higher Education and Research, Mysore, Karnataka, India.

Background: Importance of fluoride in dental restorative materials for preventing secondary caries. Several commercially available tooth-colored dental restorative materials, such as glass ionomer cement, resin composites, and compomers were used for this study.

Aim: To evaluate the amount of fluoride release from tooth-colored restorative materials [Conventional Glass Ionomer Cement (GC Fuji II)], Resin-modified Glass Ionomer Cement (ACTIVA BioACTIVE-RESTORATIVE), and Giomer (BEAUTIFIL II LS)] using ion-selective electrode (ISE) and spectrophotometer using zirconyl alizarin red dye method.

The Effect of Plaque Detectors on the Color Stability of Two Types of Restorative Materials.

J Esthet Restor Dent

January 2025

Department of Biomedical and Neuromotor Science (DIBINEM), Alma Mater Studiorum, University of Bologna, Bologna, Italy.

Objective: To investigate the color stability of a one-shade resin-based composite material (RC) and a glass-ionomer cement (GIC) after staining with plaque detectors (PDs) with different formulations and delivery forms.

Materials And Methods: Rectangular-shaped specimens (7 × 3 × 2 mm) were produced with RC (Venus Diamond One, Kulzer) and GIC (Fujy IX GP, GC) (n = 30). Further, the following PDs were used on the specimens: (1) tablets (T; Plaq-Search, TePe); (2) mouthwash (M; Plaque Agent, Miradent); and (3) light-curing liquid (L; Plaque test, Ivoclar).
