ABSTRACT
The following paragraphs discuss the significant elements of the understanding of the bioactivity of glass-ionomer and its relevance to healing the carious lesion. This information needs to be kept in perspective with the understanding that no restoration or restorative material will be proof against further caries. As caries is a bacterial disease, it is only possible to control it by modification of the bacterial flora, and all dental treatment must be predicated upon active treatment to achieve this.
