Abstract: This invention relates to a stable, single-part chewing gum product and methods of using same to effect remineralization of subsurface lesions in teeth and/or mineralization of exposed dentinal tubules. The chewing gum product contains a water-soluble cationic portion, a water-soluble anionic portion and a stabilizing component which substantially inhibits reaction between the cationic and anionic portions during storage of the chewing gum product but which allows the cationic and anionic portions to be simultaneously released at a substantially equal rate from the product when the product is chewed in the presence of saliva and/or water. The cationic portion is composed of at least one water-soluble calcium salt, and the anionic portion contains at least one water-soluble phosphate and, optionally, at least one water-soluble fluoride salt.

Abstract: A biopsy guide device and method for obtaining multiple biopsies at a target area without having to withdraw the biopsy guide device from the target area and reinsert the device. The biopsy guide device contains at least one means for receiving a biopsy obtaining instrument and a means for guiding the biopsy guide device to the target area. The biopsy guide device is secured internally at the target area by a guide mandrel. The biopsy guide device can be rotated about the guide mandrel to obtain multiple biopsies of the target area.

Abstract: The present invention relates to the problems of remineralization without demineralization of dental enamel by applying to the teeth a composition which is present in two phases which do not react with one another until introduced into the oral cavity. One phase contains at least one water-soluble calcium compound and the other contains at least one water-soluble inorganic phosphate and at least one water-soluble fluorine compound. In this way the ions which effect remineralization can be absorbed by the dental enamel and their subsequent reaction causes rehardening of demineralized areas in the dental enamel.

Abstract: This invention relates to non-aqueous compositions and methods utilizing same which are useful to remineralize subsurface dental enamel. More specifically, this invention relates to stable, single-part compositions containing calcium and phosphate salts which may be in a hydrophilic, non-aqueous vehicle and which when applied to lesions in dental enamel result in remineralization of subsurface dental enamel and/or mineralization of tubules in dentin thereby counteracting caries and/or hypersensitivity.

Abstract: A planar, partition-forming insert member, when disposed in a tube, e.g., a toothpaste tube, divides the tube into two compartments for storage of two components which are to be prevented from reacting until the product is ready for use. A dual-compartment assembly contains the two separate compartments in which the two components are stored until the compartments are opened for use. The assembly contains a dispensing tube and the planar partition-forming insert member disposed in the tube, the insert member causing the tube to be divided into the two compartments. The assembly is capable of separately storing the components in the two compartments and simultaneously dispensing the components from the two compartments.

Abstract: A two-part oral product capable of remineralizing subsurface lesions and/or mineralizing exposed dentinal tubules in teeth is composed of cationic and anionic discrete parts. The cationic discrete part contains at least one water-soluble calcium salt and, preferably, at least one non-toxic, water-soluble salt of a divalent metal other than calcium, and a first pharmaceutically acceptable carrier. The anionic discrete part contains at least one water-soluble phosphate salt and, preferably, at least one water-soluble fluoride salt, and a second pharmaceutically carrier. Preferably, one of the carriers is an aqueous carrier and the other of the carriers is a non-aqueous carrier. The cationic and anionic parts are simultaneously released from the product upon mixing of the product with water and/or saliva to form the mixed aqueous solution. In this way, calcium ions released by the calcium salt and phosphate ions released by the phosphate salt are simultaneously delivered to the tooth surfaces by the solution.

Abstract: The present invention relates to remineralization, without demineralization, by applying to the teeth a composition which is present in either one or in two phases and which does not react to any large extent until introduced into the oral cavity and upon such introduction does not rapidly precipitate. One phase systems contain at least one water-soluble calcium compound, at least one other water-soluble, non-toxic compound containing a divalent metal different from calcium, and at least one water-soluble inorganic phosphate compound. If desired at least one water-soluble fluorine compound may be added to the system. In two phase systems one phase contains the calcium and the divalent metal compounds and the other the phosphate and optionally, the fluoride compound. In this way the ions which effect remineralization can be absorbed by the dental enamel and their subsequent, but controlled, reaction causes rehardening of demineralized areas in the dental enamel.

Abstract: A dynamic table/shield apparatus contains a movable treatment table and at least one shielding block which is movable relative to the table. The apparatus effects total body irradiation treatment of a body disposed on the table while completely shielding, throughout the treatment time, a midplane of a predetermined body part from a radiation beam emitted from a radiation source during the treatment. During the treatment, the table and body are moved in a first direction at a first velocity V.sub.1 through a radiation field, and the shielding block is moved relative to the table at a second velocity V.sub.2 in a second direction opposite of the first direction. The second velocity is equal to (V.sub.1)(b/a), wherein "V.sub.1 " is the first velocity, "b" is the perpendicular distance between the the shielding block and the midplane of the body part, and "a" is the perpendicular distance between the midplane of the body part and the radiation source.
