Abstract

See full text

A device for use in retracting a gingiva from a human tooth by widening a gingival sulcus with a dental composition. The device comprises a cannula with a free end having an opening for dispensing the dental composition. The free end is shaped to be inserted with its front in the entry of the gingival sulcus, and to laterally displace the gingiva from the tooth as the cannula is moved in the gingival sulcus. The invention may help to achieve a reliable and cost effective gingival retraction treatment.
