Study Notes

Clinical Skills & Practice - Instrument Design & Recognition

There are three basic parts to an instrument, the working end, the shank, and the handle.
Handle variations include ergonomic weighting, textures, flexibility, and rigidity.
The shank is extended from the handle and connects the working end, it is the part of the instrument that allows the clinician to manipulate and control the working end.
There are two types of shanks: simple and complex, and these are further categorized as standard, extended, flexible, or rigid.
The working end is designed to be specific to the clinician's task, which results in significant micro-anatomical differences.
Sickles and curettes are two examples of working ends with varied micro-anatomy. Micro-anatomy refers to the specific design and shape of the working end.
The working end of a sickle comes to a pointed tip with a triangular cross-section and two cutting edges that meet at the tip.
The working end of a curette has a rounded toe and a semi-circular cross-section.
Sickles are designed for supra-gingival use only, on enamel, while curettes can be used both supra-gingivally and sub-gingivally.
The universal curette has a rounded back, rounded toe, and semi-circular cross-section.
The universal curette has two cutting edges and is designed for use on both enamel and root surfaces, can be used supra-gingivally and sub-gingivally.
Site-specific curettes are designed with a long, complex shank and only one working edge, specific to a particular anatomical location, and should only be used sub-gingivally.
The most common type of site-specific curette is the Gracey curette, which has multiple designs for specific tooth surfaces.

Periodontal Instruments

Periodontal instruments are classified into four types: Probes, Explorers, Sickles, and Curettes.
Periodontal probes are used for measuring sulcus or pocket depth and are designed with a smooth rounded or rectangular tip.
Periodontal explorers have a fine, wire-like working end and are used for evaluation of the location and extent of calculus deposits with maximum tactile conduction.
Sickles are specifically used on the enamel, often referred to as supra-gingival scaling, and should be avoided on root surfaces.
Sickles are used for the removal of supra-gingival calculus.
Universal curettes are used supra-gingivally and sub-gingivally for the removal of calculus deposits.
Gracey curettes are considered site-specific and designed to work on different tooth surfaces.
The design number on periodontal instruments indicates the specific design of the working end.
