ABSTRACT:
A dental adhesive delivery system provides a single usage amount of dental adhesive in a non-resealable container for use in treating a single patient. The packaged amount of adhesive may include up to the amount required to treat all of the teeth needing treatment of not more than a single patient, for example in the range of approximately 0.05 to 1.0 ml. The packaged amount may include a dose only large enough for the treatment of a single tooth or for the application of a single restoration, for example, in an amount of about 0.1 ml. The adhesive is one that includes a volatile solvent or other liquid carrier, such as, for example, water or an organic liquid such as acetone or alcohol. In the preferred embodiment, an alcohol based adhesive is provided having a filler of approximately 25% by weight. The single use container is preferably formed of injected molded plastic and includes a reservoir section that contains the adhesive and a break off section that surrounds an opening that receives a snap fit cap. A plastic and foil pouch constitutes a secondary containment volume or vapor seal which limits the escape of evaporated organic carrier or solvent. The cap and break off section are discarded and the adhesive is removed with the tip of a wand for application to the teeth of a patient, whereupon the container, which is not resealable, is discarded.
