A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.

Embodiments of the present invention provide devices (tags), systems, and methods to determine structural integrity and other states of materials-of-interest, such as dental fillings, implants, and root canal posts, to name a few, in a non-invasive and contactless way; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized backscatter-tags with sensors are implanted in such materials-of-interest. Using backscatter imaging technology, the structural integrity and other states of the materials-of-interest may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized backscatter-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the material-of-interest.

An electrical discharge irrigation device and method is described. An electrical discharge irrigation device includes a power source, a circuit coupled to the power source, and an output tip coupled to the circuit. The output tip includes a first end and a second end and a longitudinal axis extending between them, an electrode located in an interior space of the output tip configured to receive an electrical charge from the circuit and to release an electric discharge, and a ground return including an inner surface of the output tip, wherein a space between the electrode and the ground return comprises a conductive medium, the conductive medium being in contact with the electrode and the ground return to produce the electric discharge.

A root canal sealing instrument includes an elongated member that includes a shaft and a spiraled member. The root canal sealing instrument further includes a housing that encompasses at least a portion of the elongated member, wherein the housing is configured to slidably move with respect to the elongated member. The housing includes a proximal opening and a distal opening at opposing ends of the housing, wherein the proximal opening is closer to a proximal end of the elongated member than a distal end of the elongated member, and the distal opening is closer to the distal end of the elongated member than the proximal end of the elongated member. The housing further includes an interior chamber with a diameter at least as large as a first diameter of the spiraled member and a second diameter of the shaft.
