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. |
