Abstract The development of dental materials with improved properties and increased longevity can save costs minimize discomfort for patients. Due to their good biocompatibility, glass ionomer cements are an interesting restorative option. However, these have limited mechanical strength survive in the challenging oral environment. Therefore, a better understanding structure hydration process bring necessary further developments. Neutrons X-rays been used investigate highly complex pore structure, as well assess hydrogen mobility within cements. Our findings suggest that lower results not only from presence pores, but also material. relationship between microstructure, brings insights into material's durability, demonstrating need opening possibility research
