| 15 Principles of Instrumentation (1-7) | 1. Fulcrum Finger Pressure: 2. Fulcrum Finger and Middle Finger Together: 3. Fulcrum Location: 4. Middle Finger for Lateral Pressure: 5. Thumb Position and Lateral Pressure: 6. Index Finger Position: 7. Middle Finger Slightly Bent: |
| 15 Principles of Instrumentation (8-11) | 8. Middle and Index Finger Together: 9. Handle Position: 10. Wrist Motion and Finger-Flexing Motion: 11. Wrist Motion with Lateral Pressure: |
| 15 Principles of Instrumentation (11-15) | 12. Middle of Thumb Pad on Handle: 13. Adjustment of Index Finger Position: 14. Pivoting on the Fulcrum: 15. Grasp Position on Instrument: |
| 1. Fulcrum Finger Pressure: 15 Principles of Instrumentation | There is a direct relationship between the pressure on the fulcrum finger and the pressure on the instrument blade against the tooth. Keep pressures equal. |
| 2. Fulcrum Finger and Middle Finger Together: 15 Principles of Instrumentation | Keep the fulcrum finger and the middle finger together. (Built up fulcrum) |
| 3. Fulcrum Location: 15 Principles of Instrumentation | The fulcrum must be established close to the working area to position the instrument so that the lower shank is parallel with the surface of the tooth being instrumented. |
| 4. Middle Finger for Lateral Pressure: 15 Principles of Instrumentation | With all curettes, the handle and the shank of the instrument should rest on the bony side of the middle finger, right next to the fingernail. |
| 5. Thumb Position and Lateral Pressure: | The thumb position should be parallel with the curette blade, providing the operator with direct pressure through the blade onto the tooth. |
| 6. Index Finger Position: | The index finger should be bent at the first joint next to the knuckle and cocked back on the handle of the instrument. |
| 7. Middle Finger Slightly Bent: | The middle finger should be slightly bent at the first joint next to the knuckle, but not bent as much as the index finger. |
| 8. Middle and Index Finger Together: | Keep your middle and index fingers together to increase strength and stability. |
| 9. Handle Position: | Positioning the handle parallel with the long axis of the tooth is a key to proper orientation of the curette blade. |
| 10. Wrist Motion and Finger-Flexing Motion: | Flexing Motion: The most effective strokes should combine both wrist motion and finger flexing motion. Pure wrist motion makes the stroke too short and Pure finger-flexing causes fatigue. |
| 11. Wrist Motion with Lateral Pressure: | The effectiveness of the working stroke depends on combining wrist motion with adequate lateral pressure against the tooth. |
| 12. Middle of Thumb Pad on Handle: | Position the middle of the thumb pad on the instrument handle to achieve optimum pressure and control. |
| 13. Adjustment of Index Finger Position: | Lighten the pressure on the index finger and carefully readjust it so that it does not fall off the instrument as the operator rolls the handle with the thumb. |
| 14. Pivoting on the Fulcrum: | When scaling around any line angle or curvature of any tooth the operator must not only rotate the instrument in his/her fingers but also pivots on the fulcrum. |

| Hoe | If used subgingivally, thick blade will cause distention of pocket wall; lack of adaptability of wide straight cutting edge to curved root surface; will easily gouge cemental surfaces, should round sharp corners when sharpening; |
| Hoe | lack of sensitivity due to largeness of instrument (reduced tactile sensitivity); impossible to reach base of pocket without stretching/tearing pocket wall due to size, shape and angulation of blade. |
| Magnetostrictive(Ultrasonic) Scaling | Ultrasonic scalers involve a power-unit box that sits on the counter. They must be connected to a water source and they plug into an electrical wall outlet. |
| Magnetostrictive(Ultrasonic) Scaling vibrate | Ultrasonics vibrate at much higher frequencies than sonic scalers (25,000 cycles per second or higher.) The pattern of vibration is much more linear than the sonic scaler, tracing the letter “I” or a very narrow ellipse as it vibrates. |
| Swivel Direct Flow Design | _ SWIVEL inserts allow for single-handed adjustment – No need to stop scaling or to reach with your free hand to adjust the insert. |
| Swivel Direct Flow Design | Less hand fatigue* - An 18% larger handle diameter reduces finger pinching for a light touch and enhanced tactile sensitivity. |
| Swivel Direct Flow Design | The through-tip water delivery of SWIVEL Direct Flow focuses the water flow directly to the tip – reducing excess spray for improved visibility and enhanced patient comfort. |
| Piezo Scaling | The PIEZO is powered by vibrating quartz plates in the handpiece instead of a vibrating metal stacks on the back of the insert. The oscillation is provided by vibrating quartz plates built into the handpiece |
| Piezo Scaling | As a result, the PIEZO is quieter and generates less heat than the traditional magnetostrictive design. You can use the piezo with minimal water flow, or even no water flow at all. |
| Sonic Scaling | scalers, like the Titan®, are small handpiece-size devices. They sit conveniently in the delivery unit and hook up to a conventional air/water handpiece connector. |
| Sonic Scaling | the tip of a sonic scaler moves in an orbital pattern, tracing the letter “O” as it vibrates at approximately 3000-9000 cycles per second. |
| 15. Grasp Position on Instrument | The grasp should be spread out on the handle of the instrument to provide the best stability and control. This also allows consistent, even pressure and avoids finger flexing. Periodontal Instrumentation: Anna Pattison |
| The stroke for piezo ultrasonic scaler is | linear |

| Plaque | is the culprit. It is colorless and sticky. It is a live bacteria that is composed of microorganisms, food and saliva. It forms continuously. It feed on food and debris. It excretes by-products (waste), plaque's wastes are endotoxins. |
| Plaque's wastes are | plaque's wastes are endotoxins. These toxins erode gingival tissue by creating small ulcers in the gingiva. These ulcers cause bleeding. If left untouched, plaque calcifies (calculus -rough surface) and attracts more live bacteria. |
| Which direction we hand scale? | Coronal-apical and Apical-coronal. |
| What does calculus to gingiva | calculus grows larger and pushes the gingiva away from the tooth allowing the live plaque to get closer to the attachment fibers and ultimately bone |

| Infection control —Power-driven instrumentation- | Not all components of electronically powered devices can be sterilized |
| Water production and visibility —Power-driven instrumentation- | Position the patient in a supine position with the head turned to the side and chin pointed down. |
| Primary or newly erupted teeth with large pulp chambers —Power-driven instrumentation- | recommended low to medium power settings and adequate water flow are used because the amount of heat generated will not be sufficient to harm the pulp. |
| Oral conditions —Power-driven instrumentation- | Ultrasonic or sonic use is contraindicated for patients with hypersensitivity, demineralized areas, porcelain or composite resin restorations, and titanium implants (unless a specially designed tip for this purpose is used) |
