| Outline of Final Research Achievements |
Mineral trioxide aggregate (MTA) is a promising biomaterial in endodontic treatments. However, a disadvantage of this material is its difficult handling properties, namely, relatively long setting times. Thus, a need has been identified for the development of materials more suitable for endodontic applications. Calcium phosphate cement (CPC) has become a subject of interest in medical applications as bone graft biomaterials. For endodontic treatments, fluorapatite-forming CPC with tricalcium silicate (FA-forming CPC with TCS) was developed and evaluated for endodontic cements.
In results, setting time of FA-forming CPC with TCS was shorter than that of MTA, on the other hand, it has similar sealing ability and biocompatibility as those of MTA. These results suggested that FA-forming CPC with TCS had an appropriate characteristic as endodontic cements. Therefore, FA-forming CPC with TCS may be useful for endodontic applications.
