ABSTRACT:
A specialized dental bur designed to easily enter the periodontal pocket to perform root planing and curettage without the need for incisions has a cutting head attached to a shank. The cutting head has a combined structure of a narrow, hemispherical tip, cylindrical portion of larger diameter and a transition portion having a curved surface between them. Color coding or marking enables bur segregation and enables depth determination. The bur can be used for abrading tooth root, gingiva, and bone structures without gingival incisions.
