摘要：
An improved dental instrument is provided for facilitated placement of gingival retraction cord into the gingival crevice surrounding a tooth. The instrument includes a curved edge designed to conform to the curvature of a root surface of a tooth at the gingival level. The gingival retraction cord can thus be placed quickly and easily without significant risk of damage to periodontal attachment tissue at the base of the gingival crevice.
