Abstract
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. T…
