A method of anesthetizing a tooth requiring tooth preparation, caries removal or manual manipulation thereof is disclosed. The method includes the steps of applying a composition having a high concentration of potassium to the tooth requiring tooth preparation, caries removal or manual manipulation, the composition being adapted to anesthetize the tooth so that the tooth may be drilled or manually manipulated, whereby the potassium enters the dentinal tubules and odontoblastic fibrils and penetrates the pulpal tissues of the tooth for anesthetizing the tooth. The improvement consists essentially of applying a solution of EDTA, EGTA, and citric acid to the tooth before the application of the potassium composition, the solution of EDTA, EGTA, and citric acid effectively removing a smear layer from the tooth so as to facilitate the penetration of the potassium solution through the dentinal tubules and odontoblastic fibrils.

Method of using potassium nitrate for pain reduction

A delivery vehicle for a silver ion source such as silver nitrate and the like, suitable for use in the treatment of menorrhagia, comprises a plurality of physiologically inert beads bearing a tissue cauterizing amount of a silver ion source. Preferably the beads are made of a physiologically inert polymer, ceramic or stainless steel. The silver ion source preferably is silver nitrate and can be substantially pure silver nitrate, or can comprise silver nitrate in combination with a physiologically tolerable binder or a diluent. Suitable binders include physiologically tolerable synthetic polymeric binders, polysaccharide binders, and the like. Diluents can include other salt materials such as potassium nitrate. The beads are useful in treating menorrhagia of a mammalian uterus. The beads can be delivered to the uterus via a catheter, and are distributed throughout the uterine cavity by uterine massage or like expedient. Silver ions are delivered to the endometrium and cause necrosis of the endometrial tissue. The silver ions remaining within the uterine cavity can then be neutralized with a sodium chloride solution delivered to the uterus e.g., by catheter, and the beads recovered from the uterus.

Method for treating menorrhagia

An abrasive or polishing device for dispensing and applying primers, cavity liners, varnishes, therapeutic agents, and/or adhesives into or onto tooth structure or within a cavity in a patient's tooth. The primers, liners, varnishes, or adhesives may contain a therapeutic agent or a drug, such as fluoride-containing compound or a tooth desensitizing agent, such as a cationic salt of oxalic acid, potassium nitrate, or similar compounds. The adhesive or therapeutic may be applied directly to the tooth surfaces by the elastomeric abrasive or polishing impliments. Alternatively they may be impregnated within the devices and applied directly, optionally using water as a vehicle. The application devices may also, optionally, contain an abrasive so that the application device simmultaneously abrades the tooth structure while applying an adhesive or therapeutic agent.A dispensing and abrasive device for simultaneously dispensing primer and/or adhesive and abrading tooth material within a cavity in a patient's tooth. The device includes a carrier material, a liquid primer and/or adhesive composition and abrasive powder having a hardness greater than the hardness of dental tooth material. The liquid primer and/or adhesive and the powder are supported by the carrier material.
