Study Notes
Instrument Design
- Periodontal instruments have three basic parts: the working end, the shank, and the handle.
- Handles are ergonomically designed for comfort and grip.
- Handles can vary in size, weight, texture, and rigidity based on clinician preference.
- Shanks connect the working end to the handle and facilitate access to different areas in the mouth.
- Shanks can be simple or complex, with varying degrees of bend and flexibility.
- Working ends are the functional part of the instrument and are designed for specific tasks.
- Working ends can be classified into types such as sickle, curets, and explorers.
Working End Micro-Anatomy
- The working end has micro-anatomical components:
- Face: The flat surface of the blade.
- Lateral surface: The side of the blade.
- Cutting edge: The sharp edge that removes calculus.
- Toe/tip, Middle, and Heel: Anatomical divisions of the working end.
Working End Types
- Sickle:
- Pointed tip, single cutting edge, triangular cross-section.
- Curets:
- Rounded toe, two cutting edges, semi-circular cross-section.
- Universal curets:
- Rounded back, rounded toe, semi-circular cross-section, single cutting edge, and a long, complex shank.
- Can be used on multiple surfaces.
- Site specific curets:
- Semi-circular cross-section, one cutting edge per working end, long complex shank, only used on specific surfaces and areas.
Instrument Classification
- Instruments have a design name and a design number.
- The design name identifies the school or designer of the instrument.
- The design number is assigned based on the instrument's design, material, and function.
Periodontal Instruments
- Periodontal instruments are used for assessment and deposit removal.
- Explorers are used to detect calculus, plaque, and other irregularities.
- Sickles are efficient for removing supra-gingival calculus.
- Curets are used for sub-gingival calculus removal.
Periodontal Probes
- Periodontal probes are used for measuring pocket depths, evaluating tissue health, and locating calculus deposits.
- They have rounded or rectangular working ends.
- Some probes have millimetre markings for precise measurements.
Blade Angles
- Blade angle and tilt are important for efficient and safe calculus removal.
- Specific instruments and techniques require unique blade angles.
Site-Specific Curets
- Site-specific curets are designed for specific areas of the mouth.
- Common examples include Gracey curets.
- Gracey curets are classified by their design number and are used on specific teeth and surfaces.
Gracey Curets Examples
- Gracey 1/2 and 5/6 are used for anterior teeth.
- Gracey 9/10 are used on molars.
- Gracey 11/12 and 13/14 are used for multi-rooted teeth.
