Abstract This chapter focuses on dental biomaterials designed for permanent placement in the mouth. The development of flowahle polymer-ceramic composites is traced and their rheological properties, such as pseudoplasticity and thixotropy, discussed. Also considered are some materials that are being developed for root canal therapy, including calcium phosphate cements. There is vast scope for research into materials development, clinical applications and fundamental mechanisms. 

Key words dental biomaterials, resin composites, flowahle composites, endodontic materials, calcium phosphate cements. 

According to the Oxford English Dictionary, to inject is to to drive or force (a fluid, etc.) into a passage or cavity, as by means of a syringe, or by some impulsive power said especially of the introduction of medicines or other preparations into the cavities or tissues of the body.  

However, this chapter focuses on dental biomaterials intended for permanent placement. Three areas of research and development are considered and critiqued
