Conventional dental cements lack certain properties such as the facilitation of optimal re-mineralization. The novel bioactive glass-ionomer dental and bone cement formulations disclosed herein induces mineralization at the in vivo interface and exhibits superior handling properties (shorter setting time) and mechanical properties (improved bond strength to dentin and flexural strength). The present invention presents the first bioactive glass-ionomer dental cement with mineralization power, exhibiting improved bond strength to tooth structure, sharp setting time and superior mechanical strength. Materials of this invention can be used as bone cement, as a dental filling (restorative material), as a liner for deep cavity preparations (to avoid root canal therapies and tooth sensitivity), or as a luting cement to cement dental crowns. Moreover, it can be utilized in a flowable resin for use as a coating to prevent dental caries in their initial steps (white spots).
