    Abstract: Disclosed are endodontic filling materials and methods. A method for filling a dental root canal may include providing a hydrosetting filling material and inserting the hydrosetting filling material into the dental root canal, the material setting in the root canal to form a biocompatible filling. The hydrosetting filling material comprises a hydrogel former and a filler. The hydrogel former is at least one of a reactive organic hydrogel formers, an inorganic hydrogel formers, and a non-reactive organic hydrogel formers, and the filler is at least one of a self-hardening and a non-hardening filler. Plural filling material precursor compositions that collectively contain hydrogel formers and fillers may be provided.

    Abstract: An electron paramagnetic resonance device includes a crystalline, emission-sensitive mass and a housing containing the device. The mass includes structurally incorporated carbonate content in a range of about 3% by weight to about 10% by weight of the mass, one or more structurally incorporated non-calcium metallic cations, and one or more structurally incorporated phosphate anions. When irradiated with a known source, the EPR device may function as a reference. When unirradiated, the EPR may function as a dosimeter. As a dosimeter, the EPR device may be used as a personal dosimeter or as a monitor for inanimate objects being subjected to radiation sources. The EPR dosimeter may be used for both gamma radiation and neutron radiation measurements.

    Abstract: A dosimeter for EPR dosimetry systems includes a carbonated hydroxyapatite cement formed by mixing a cement powder and a cement liquid in a ratio of a range of about 0.5 to 5.0 powder-to-liquid ratio. The cement powder includes one or more calcium phosphate compounds and one or more carbonate compounds. The cement liquid includes a sodium phosphate solution. The cement, when irradiated by a radiation source, is capable of producing a measurable signal as a spectrally clean EPR spectrum. Furthermore, the measurable signal is proportional to the received radiation dose
