Study Notes

Periodontal Instrumentarium

Periodontal instruments are tools used in dentistry for various procedures, including locating, measuring, and marking pockets on teeth.
Periodontal probes are used to assess periodontal pockets. They're tapered, rod-like instruments marked in millimeters, with a blunt tip.
Types of Periodontal Probes:
- University of Michigan "O" probe with markings at 1, 2, 3, 5, 7, 8, 9, and 10mm (Left)
- Nabers probe, for detecting furcation areas (Right)
- Marquis color-coded probe, with 3-mm markings
- UNC-15 probe, a 15mm long probe with millimeter markings at each millimeter and color coding at the 5th, 10th, and 15th millimeters (15mm long)
- WHO probe with a 0.5mm ball tip and millimeter markings at 3.5, 8.5, and 11.5mm, color-coded from 3.5 to 5.5mm.
Explorers: Used to locate subgingival deposits and carious areas and assess the smoothness of the root surfaces after root planning.
Scaling and Curettage Instruments: Are used to remove plaque, calculus, altered cementum from crowns and roots of teeth. Tools include:
- Scalers – for removing calculus
- Curettes – for removing infected cementum and epithelium lining pockets. Two families; Scalers and Curettes.

Types of Sickle Scalers

Sickle scalers are used for supragingival scaling
Basic characteristics: Flat surface, triangular shape, two cutting edges, pointed tip, blade-shank angle is 90°.
Different types exist, including CK-6 scaler—used for surgical debridement, and Jaquette scaler.

Curettes

Curettes are used to remove deep subgingival calculus, perform root planning, and remove the soft tissue lining periodontal pockets.
Two common types include Universal curettes and Gracey curettes.

Instrument Activation and Adaptations

Adaptation: Technique used in placement of the instrument on the tooth.
Angulation: Angle between the instrument blade and the tooth surface, necessary for proper activation and effectiveness in different procedures, such as subgingival scaling and root planning.

Working Strokes

Different types of strokes (e.g., oblique, vertical, horizontal, circumferential) with specific instruments, including variations specific to Gracey curettes.
