This course is for dental professionals and students who want to learn about using glass ionomer cement (GIC) in clinical dentistry. The course highlights the unique properties of GIC, including prolonged fluoride release, remineralization, and antibacterial activity. Modern glass ionomer cement offers superior aesthetics and durability and is often an ideal choice for restorations, liners, bases, luting agents, fissure sealants, and adhesives for orthodontic brackets. The lessons will explore using GIC for various applications, including sealants, restorations, the Hall technique, and SMART restorations. We'll conclude with an overview of the Plan-Do-Study-Act (PDSA) cycle. This tool can help learners effectively and sustainably integrate GIC (or any new device or process) into their practice to improve oral health outcomes.
