摘要： Mouth rinses, dentifrices, lozenges, confections, chewing gums, and similar delivery vehicles containing non-toxic soluble calcium are used prior to administration of a fluoride-containing composition to increase the effectiveness of the fluoride therapy. An effective amount of calcium is released into the oral cavity and allowed to penetrate into the oral tissue. Calcium-bound fluoride deposits form in the oral tissue upon subsequent administration of the fluoride-containing composition to provide increased salivary, plaque and oral tissue fluoride concentrations.

摘要： Disclosed are dental compositions and methods. In accordance with one embodiment, a dental composition includes calcium, fluorine, which is generally present in the form of fluoride, and phosphate or another stabilizing anion. The composition is stable as against precipitation of calcium fluoride during transport and storage, but is unstable against the precipitation of calcium fluoride in the oral cavity of a human. In many embodiments, the amount of fluoride may be less than the amount of fluoride used in a comparable composition intended for a similar purpose. A dental method comprises applying the composition to the oral cavity of a patient, whereupon calcium fluoride precipitates from the composition.

摘要： Combining nanosized particles of a source of desired dental restorative, repair or therapeutic materials with strengthening agents in various generally nanosized form such as whiskers, fibers, particles and the like in a resin matrix provides a highly strain resistant composite which more effectively releases the therapeutic agents. The utilization of nano sized particles of the therapeutic agent in the combination enables observation of significantly improved therapeutic results.

摘要： Disclosed are dual-phase cement precursor systems and related methods and kits. The cement precursor systems are composed of a first and second discrete phases, at least one of which is aqueous. When combined, the cement precursor phases form a cement that is suitable as a bone graft material for bone repair procedures. In preferred embodiments, the materials are highly biocompatible, osteoinductive, and bioresorbable. A number of different but not mutually exclusive cement chemistries may be employed in the cement precursor systems. For instance, hydrogel-forming polymer cements, carboxyl/calcium cements, or calcium phosphate cements may be employed.
