In accordance with the principles of modern operative dentistry, to conserve tooth structure and to use therapeutic restorative materials, an understanding of the carious process in dentine and the biological properties of glass-ionomer cements (GICs) are necessary. Delineation of the outer necrotic from the inner vital and remineralisable carious dentine allows for the preservation of tooth structure. This delineation is not possible when relying on visual and tactile perceptions, but requires the use of a caries detecting dye. GICs are ideal dentine substitutes because of their anticariogenic properties, stable long-term ionic bonding, and ability to assist the process of remineralization. The range of usage of these restorative materials continues to expand with the development of improved products.
根据现代牙体牙髓病学的原则，为了保存牙体组织并使用治疗性修复材料，了解牙本质中的龋病过程以及玻璃离子水门汀（GIC）的生物学特性是必要的。区分外层坏死的牙本质与内层有活力且可再矿化的龋坏牙本质有助于保存牙体组织。依靠视觉和触觉感知无法做到这种区分，而是需要使用一种龋病检测染料。由于具有防龋特性、稳定的长期离子键以及协助再矿化过程的能力，玻璃离子水门汀是理想的牙本质替代材料。随着改良产品的开发，这些修复材料的使用范围不断扩大。
