Professor Hien Chi Ngo is a distinguished dental professional with extensive expertise in clinical practice, research, and education. Throughout his career, he has actively treated advanced cases of caries and erosion while focusing his research on dental materials and cariology. His work emphasizes the clinical management of caries in elderly and medically compromised patients, as well as the interactions between glass-ionomers, the oral environment, and silver diamine fluoride.
As an educator, Professor Ngo has published and lectured extensively on dental materials, Minimal Intervention Dentistry, and clinical cariology. He has served on the editorial boards of multiple dental journals and regularly contributes to international conferences. His leadership extends across six dental schools on three continents, where he has held deanships and directorships, including in the UAE and Western Australia.
Professor Ngo's contributions to dentistry have earned him global recognition, with accolades from the Minister of Health in Vietnam and the International College of Dentists. Additionally, he has served as a technical consultant to several dental organizations and co-invented multiple dental products, significantly advancing the field of dental care.

Glass-ionomer cements: Alternative Material in the Amalgamless Super-aging Era
In July 2024, the European Commission announced a proposal to phase out dental amalgam by January 1, 2025, a move set to happen five years earlier than previously planned. This includes a complete ban on the manufacture and export of amalgam within the EU. Although dental amalgam has been a reliable and cost-effective choice for direct restorations, particularly for underserved populations, the impending phase-out raises concerns about potential cost increases, clinical uncertainties, and possible barriers to patient access. Despite ongoing efforts by dental manufacturers to develop alternatives, progress in this area has been limited. Currently, the main substitutes for dental amalgam are composite resins and glass ionomer cements. This lecture aims to equip clinicians with the knowledge to adapt to a post-amalgam landscape, highlighting notable advancements in glass ionomer technology, particularly glass hybrid technology. This innovation enhances the effectiveness of glass ionomer, making it suitable for specific Class II restorations. Additionally, the presentation will outline practical steps clinicians can take to ensure the performance of these alternative materials, while also delving into tooth-preserving restorative techniques. By embracing these advancements, dental professionals can continue to provide high-quality care despite evolving regulatory frameworks.
