Abstract: A sterilization container is provided which includes interengageable, overlapping, hollow cap and base portions which, when combined, define a cavity and a fluid passage in the region of overlap to allow for continuous fluid flow from the outside to the inside of the container.

Abstract: A hygiene-promoting, dental mandrel/polishing-wheel system. The system includes a universal mandrel which can be mounted for rotation either within a chuck or upon an arbor. The mandrel includes a wheel anchor station which allows quick axial fitting and removal of a disposable polishing wheel.

Abstract: Apparatus for aspirating liquids and debris which collect near the working region of a dental dam. The apparatus includes a head adapted to extend removably and sealingly through a stretched aperture in such a dam, with the head having aspirating ports that open on opposite surfaces of the dam. These ports couple with an exhaust passage, which extends on the nonworking side of the dam, and which is adapted for coupling to a flexible suction conduit.

Abstract: Ring-like apparatus for use in handling endodontic files. The apparatus includes a socket member forming a tapered socket having a larger upper end and a smaller lower end. A deformable tapered cushion is receivable in the socket, with a portion of the cushion projecting through the socket's lower end. When such portion is pulled downwardly and then released, it bulges against the socket member, at the socket's lower end, forming a bulge which holds the cushion releasably in the socket. Files may be embedded releasably in the opposite (upper) end of the cushion. The apparatus includes a band enabling wearing of the apparatus on a user's finger. A trough arrangement formed in the apparatus, cooperating with a calibration scale, allows the user to adjust, with his free hand, the position of a file depth marker slidably held on a file's shaft.
