In accordance with the present invention, an improvement is provided in an annular orthodontic band for encircling the crown of a molar or bicuspid tooth wherein an antitip rest extends inwardly from a location along the mesial portion of the occlusal edge for a distance which is sufficient for the rest to be engageable with the occlusal surface of the tooth to prevent the mesial side of the band from sliding past the mesial ridge of the tooth. Additional antitip rests can be provided along the occlusal edge of one or more of the buccal, lingual and distal portions of the band for additional bodily support for proper positioning of the band. A ledge can be provided on the band for engagement by an instrument to seat the band on the tooth. A ball hook can be positioned on the gingival side of the ledge of a band for an upper tooth.

A device for retracting and storing a length of hose is provided. The device is housed within a dental cabinet and includes a rectangular compartment formed by integral side walls and front and rear walls. A plurality of spool supports are positioned adjacent to the side walls. A spool is positionable within the compartment. A length of hose anchored at the rear wall is routed under the spool and through an opening in an instrument panel of the dental cabinet. At the distal end of the hose is attached the desired dental tool. In retracted position, the hose hangs in a loop or bight with the spool supported on the bight. The weight of the spool normally keeps the hose under tension. The device is operated by pulling on the distal end of the hose such that the spool is lifted onto and secured by the spool supports. In this position, tension is released from the hose.
