Composition and methods that include potassium nitrate for whitening and/or reducing tooth sensitivity. The dental compositions may optionally include a dental bleaching agent, such as hydrogen peroxide or carbamide peroxide. The dental compositions may be applied directly to the person's teeth, or they may be loaded into a comfortable fitting, flexible, thin-walled dental tray and placed over the person's teeth. In that case, the dental compositions will include a tackifying agent, such as carboxypolymethylene, dispersed within a solvent, which assists the composition in retaining the dental tray over the person's teeth as a result of the adhesive properties of the dental composition rather than due to mechanical interlocking of the tray over the person's teeth. The dental compositions may further include anticariogenic and antimicrobial agents.

A probe comprising two spaced electrodes is provided between which electrical resistance through enamel, dentine or tooth tissue is measured. The electrodes comprise inner and outer coaxial electrodes spaced by an insulating layer. The diameter of the probe is preferably 1 mm. The tip of the probe may be shaped to match the surface being measured. The signal from the probe is A to D converted for analysis. The rate of change of resistance gives a measure of the rate of change of moisture level (porosity). The porosity is related to tooth sensitivity and so the system can provide an objective measurement of tooth sensitivity.

A one-component paste-consistency dental material which cures upon contact with oral fluids intended primarily for use as a temporary restorative/cement. The formulation includes solid particles reactive with water dispersed in a hydrophobic viscous binder which, upon exposure to moisture, will solidify to a depth in excess of 8 mm measured from the surface/water contact area. The curing mechanism relies on both formation of hydrates and reaction of organic polyacids with alkaline glass or metal oxides, or the salts of metal oxides with weak acids. The resulting cured material is non toxic, resistant to deterioration in oral fluids, possesses adequate water resistance, and, optionally, may release fluoride desirable for prevention of secondary decays and alleviation of postoperative tooth sensitivity.
