ABSTRACT:
The present invention relates to an instrument for subgingival scaling, root planing and maintenance of periodontal health. The instrument has an elongated body with a handle portion, a terminal shank portion, a working end, and a gauge. The terminal shank portion includes a base having a first portion, which is coaxial with the handle portion, and a second portion, which is angled from the first portion. The working end has a rear heel portion adjacent to the second portion and a front toe portion. Between the heel and toe there is a blade edge extending lengthwise. The gauge is arranged along the annular surface of the second portion of the terminal shank. In order to measure the periodontal health of the patient on whom the instrument is being used, the instrument is inserted into the periodontal space between the tooth and the gum. The depth of the periodontal space is determined by reading the marking on the gauge which meets the gumline.
