| Research Abstract |
The result of this study shows that crystal formation is a common behavior of a "hydrophilic" resin composition of bioglass/resin composites in water over long-term, instead of in simulated body fluid. These crystal depositions consisted of calcium carbonate (CaCO_3). Such crystal formation may be accelerated in an ion-rich environment such as artificial saliva or dentinal tubule fluid. However, further efforts will be focused on the relation between the ingredients of composite materials and reacting mineralized products in test solutions that are more useful as self-healing materials in clinical conditions.
