Study Notes
Periodontal Instruments Overview
- Periodontal instruments serve specific functions: calculus removal, root surface planning, curetting gingival walls, and diseased tissue removal.
- Main components of instruments: blade, shank, handle.
Periodontal Probes and Explorers
- Periodontal probes measure pocket depths and configurations; they feature a tapered, calibrated rod with a blunt tip.
- Probes are inserted gently into the pocket to assess depth; alignment with the tooth's long axis is crucial.
- Explorers detect calculus deposits and caries in dental surfaces.
Gracey Curettes Classification
- Double-ended Gracey curettes are categorized for various tooth types:
- Gracey # 1-2 and 3-4: For anterior teeth
- Gracey # 5-6: For anterior teeth and premolars
- Gracey # 7-8 and 9-10: For posterior teeth, facial and lingual
- Gracey # 11-12: For mesial surfaces of posterior teeth
- Gracey # 13-14: For distal surfaces of posterior teeth
- Recent additions include Gracey # 15-16 and 17-18, designed for deeper access.
Types of Scaling Instruments
- Sickle scaler: Triangular shape with double cutting edges; effective for calculus removal within 1 mm of the gingival sulcus.
- Curette: Spoon-shaped with a rounded tip, used for scaling, plaque removal, and surface planning.
Ultrasonic Units in Periodontology
- Magnetostrictive units: Elliptical tip vibration allows usage on all sides.
- Piezo-electric units: Linear tip vibration with active surfaces on only two sides.
- Ultrasonic units operate in a wet field at 20,000 to 45,000 cycles/second, facilitating visualization of deep pockets during scaling.
Specialized Periodontal Instruments
- Various periodontal knives, such as Kirkland and Orban knives, are used for surgical procedures including gingivectomy.
- Electrosurgery is employed for incisions and tissue management but is less common in general dentistry.
Furcation Assessment
- Naber’s probe is used to evaluate furcation areas, especially effective due to its curved, blunt design.
Probe Markings and Depth Indicators
- Periodontal probes come with markings every 3mm, and color coding for specific measurements aids in depth assessment and understanding.
Types and Features of Curettes
- Two main curette types: universal and area-specific.
- Universal curettes: Suitable for various teeth by adjusting the operator's technique; exemplified by Barnhart and Columbia curettes.
- Gracey curettes: Area-specific, optimized for complex root anatomy; feature an offset blade angled at 60-70 degrees from the shank.
Summary of Sickle Scalers
- Sickle scalers feature flat surfaces and dual cutting edges converging at a pointed tip, capable of effective calculus removal without damage.
- Variations include Morse sickles for tight interproximal spaces and differently shaped shanks for specific tooth types.
Functional Role of Curettes
- The curette is integral for deep subgingival calculus removal and root planning, designed to minimize soft tissue trauma while maximizing access to root surfaces.
Periodontal Probes and Their Functions
- Naber’s probe is specifically designed for evaluating furcation areas due to its curved, blunt tip.
- Typical periodontal probes feature millimeter markings for depth measurement and determining pocket configuration.
- Probes can have calibrations or color coding at intervals of 3 mm and specific millimeter sections, facilitating accurate assessments.
Types of Periodontal Instruments
- Periodontal instruments include blades, shanks, and handles tailored for specific tasks like calculus removal and root surface planning.
- Explorer instruments help locate calculus and caries deposits within the periodontal structure.
Sickle Scalers
- Sickle scalers are distinct for their triangular cross-section and have two converging cutting edges, providing a strong tip.
- Used with a pull stroke technique, they are effective for removing calculus positioned just below the gingival sulcus.
Curettes
- Curettes have a spoon-shaped blade and rounded tip for scaling, curetting, and removing plaque and stains.
- They allow effective access to deep pockets with minimal trauma to the soft tissue.
- Two types exist: universal curettes, adaptable to various tooth areas, and area-specific Gracey curettes, designed for particular anatomical zones.
Ultrasonic Scaling
- Two ultrasonic units: magnetostrictive (elliptical vibration allowing all sides) and piezo-electric (linear vibration limiting to two active sides).
- Operate in wet fields, aiding in visualizing deep pockets and furcations during scaling and root planing.
Surgical Instruments
- Instruments include periodontal knives for gingivectomy, interdental knives, and surgical blades for specific tissue management.
- Procedures might utilize electrosurgery techniques such as electrosection for incisions and electrocautery for hemorrhage control.
Curette Specifications
- The curved blade and rounded toe of curettes enhance adaptability to the root surface.
- Universal curettes have 90-degree angled blades allowing versatile application across different areas of the dentition.
- Gracey curettes feature angled offset blades (60–70 degrees) for superior adaptation to complex root anatomy.
Additional Tools
- Sickle scalers and curettes are critical for effective plaque management and periodontal treatment, with designs tailored for specific oral regions.
- The Morse sickle is a miniature scaler optimal for challenging interproximal spaces, particularly in the mandibular anterior area.
