ABSTRACT:
A dispensing system for dental material made of two components has a dual chamber cartridge that releasably connects to an applicator. The chambers of the cartridge are located in an over-under orientation relative to the user's grip on the applicator, enabling the system to be especially useful for placing dental material in regions of the patient's oral cavity that are difficult to access. Certain embodiments of the invention include a static mixing assembly having a swivelable cannula, and an exit conduit of the mixing assembly is optionally curved along its length. Other aspects of the invention relate to a reusable hygienic sheath useful for covering a dual chamber cartridge as well as a single chamber cartridge.
