Dental compositions are disclosed. A dental composition can include a reaction produce of a reaction mixture comprising a first mixture and a second mixture. The first mixture can include a ceramic based biomaterial, and the second mixture can include mineral trioxide aggregate and a phosphoric acid monomer.

The endodontic point containing ultrasonic deformable material is a filler for root canal therapy that decreases in viscosity when subjected to ultrasonic waves. Once the point is inserted into a prepared tooth space, such as a prepared and cleaned root canal, the point is subjected to ultrasonic waves. The ultrasonic waves cause the viscosity of the point to lower, thus allowing the point to flow into voids in the tooth space and allow air to escape from the voids. The point then hardens and remains in the shape acquired when at low viscosity once application of the ultrasonic waves is stopped.

The present invention relates to a composition for a single-paste type hydraulic endodontic filling material comprising dimethyl sulfoxide (DMSO). According to one aspect of the invention, there is provided a single-paste type hydraulic endodontic filling composition, comprising a calcium silicate component and DMSO.

A gutta-percha-silver composite with determined weight percentage and particle size, is provided. The composite exhibits electro-conductivity greater than the standard gutta-percha composites. The new material simplifies root canal treatments, shortens the times both for clinician and patients, and reduces the exposure to patients from X-rays. The material is not only electro-conductive; it is anti-bacterial, which improves the outcomes of the procedures. Also, it has improved thermal conductivity, and mechanical properties.

Proposed are a method of preparing new biomaterials for dental pulp regeneration and a composition of new biomaterials prepared accordingly. The composition of new biomaterials prepared according to the method of preparing new biomaterials for dental pulp regeneration by mixing a first precursor containing calcium silicate-based cement (CSC) at an appropriate concentration and a second precursor containing a secretome of dental pulp-derived mesenchymal stem cells in an appropriate ratio and then drying the resulting mixture under appropriate drying conditions is characterized by further improving the osteogenic differentiation ability of dental pulp stem cells compared to existing materials while maintaining the microhardness of the composition to an appropriate standard. In addition, the composition is advantageous in that an aesthetic effect is excellent by not causing tooth discoloration.

A root canal filling material incorporates heat conductive particles of sub-micron size dispersed in a heat flowable matrix of endodontic filling material. The particle size is 1 micron or less (e.g., 0.5 to 1 micron, or nanoparticles of 100 nm or less). The addition of high heat conductive particles in the heat flowable matrix material improves the overall heat conductivity of the root canal filling material. During root canal treatment procedure, the filling material softens more thoroughly to fill the root canal apex and to form a seal of higher integrity at the root canal apex area, at a significantly lower operating temperature. The inventive filling material may be provided in bulk (e.g., pellet form) for use with an injection tool that heats and injects softened filling material into root canal cavities, or pre-shaped in the form of dental root canal filling cones (or points).
