摘要： A dental restorative composition is provided that includes a polymerizable resin, a substantially translucent structural filler, a nanofiller having a mean particle size less than 100 nm, and at least one rheology-modifying additive. In one embodiment, the structural filler has a refractive index substantially similar to that of the polymerizable resin, a coarse particle fraction, and a fine particle fraction having a mean particle size greater than 0.1 μm and smaller than the mean particle size of the coarse particle fraction. The relative ratio of the coarse particle fraction to the fine particle fraction is in the range from about 12:1 to about 2:1 by volume, the particle size distribution of each fraction is essentially monomodal, and the D(90) of the fine particle fraction is less than or equal to the D(10) of the coarse particle fraction.

摘要： Methods and systems for using a curable material for endodontic processes are provided. The method comprises using an electroactive composition to cure and optionally un-cure the material. Using an electroactive composition allows for easy introduction of the material without unwanted complexity or side effects. It also allows for easy removal and replacement if desired.
