Sickle Scalers
TLDRThe video script provides a detailed guide on the proper use of sickle scalers, dental instruments designed to remove calculus deposits from the crowns of teeth. It emphasizes that sickle scalers are not suitable for root surfaces and highlights the triangular cross-section of the working end, which is crucial for super gingival instrumentation. The script outlines specific techniques for using a sickle scaler on both anterior and posterior sextants of the mouth, with a focus on correct positioning, angulation, and instrument handling. The importance of maintaining a 70 to 80-degree angle between the instrument and tooth surface is stressed, along with the need to reassess and adjust both the practitioner's and patient's positions throughout the procedure. The summary also notes the correct identification of the working end of the instrument for effective use on molars, ensuring the lower shank is parallel to the distal surface for optimal results.
Takeaways
- 🦷 A sickle scaler is a dental instrument used to remove calculus deposits from the crowns of teeth.
- ❌ Sickle scalers should not be used on root surfaces.
- 🔪 The working end of a sickle scaler is triangular in cross-section, designed for super gingival instrumentation.
- 📐 It features a pointed tip and two cutting edges, with the face perpendicular to the lower shank.
- 🔄 Level cutting edges require the lower shank to be tilted towards the tooth surface for correct angulation.
- 📍 Practice using the sickle scaler on the anterior sextant, starting with the mandibular left central incisor facial aspect.
- 🧍 Self-assess and correct your and the patient's position before and throughout the procedure.
- 🔩 Establish a 70 to 80-degree instrument to face to tooth surface angulation for effective scaling.
- 🌊 Use overlapping strokes and roll the instrument handles slightly between strokes to maintain adaptation.
- 🔄 Check and maintain the correct angulation while working across the tooth surfaces.
- 🦴 For posterior sextant practice, ensure the correct working end is selected, with the lower shank parallel to the distal surface.
- 🔄 Tilt the lower shank towards the distal surface to achieve a 70 to 80-degree angulation for the facial aspect of the tooth.
Q & A
What is a sickle scaler used for?
-A sickle scaler is a dental instrument used to remove calculus deposits from the crowns of the teeth.
Why should sickle scalers not be used on root surfaces?
-Sickle scalers are designed for super gingival instrumentation and are not suitable for root surfaces due to their triangular cross-section and pointed tip.
What is the design of the working end of a sickle scaler?
-The working end of a sickle scaler is triangular in cross-section, which limits its use to super gingival instrumentation.
How should the cutting edges of a sickle scaler be positioned in relation to the tooth surface?
-The cutting edges should be level with one another, and the lower shank must be tilted slightly toward the tooth surface to establish correct angulation.
What is the correct initial position for using a sickle scaler on the anterior sextant?
-The working end should be positioned near the midline of the tooth, with a 70 to 80 degree instrument to face to tooth surface angulation, and the tip aimed toward the mesial surface of the tooth.
How should one maintain adaptation of the sickle scaler while working on the tooth?
-By using overlapping strokes and rolling the instrument handles slightly between strokes to maintain adaptation as you work across the tooth surface.
What is the correct working end to use when practicing on the mandibular right first molar?
-The correct working end is the one where the lower shank is parallel to the distal surface and the functional shank goes up and over the tooth.
What is the initial position for the tip of the sickle scaler when working on the distal facial line angle of the mandibular right first molar?
-The tip should aim toward the back of the mouth, as this is the direction in which you are working.
How should the lower shank be positioned to maintain correct angulation when working on the distal surface?
-The lower shank must be tilted toward the distal surface to establish a correct angulation of between 70 and 80 degrees.
What is the importance of reassessing position and grasp during technique practice?
-Regularly reassessing position and grasp ensures that both the practitioner and the patient are comfortable and that the technique is being performed correctly and effectively.
Why is it necessary to work at least halfway across the mesial surface from both the facial and lingual aspects of the tooth?
-This ensures thorough cleaning and removal of calculus deposits from the entire mesial surface, as the other half of the surface will be instrumented from the lingual aspect.
What is the angle at which the sickle scaler's face should be positioned relative to the lower shank?
-The sickle scaler's face should be at a 90-degree angle to the lower shank to maintain proper angulation and effectiveness of the instrument.

🦷 Introduction to Using a Sickle Scaler on Anterior Teeth
The paragraph introduces the use of a sickle scaler, a dental instrument designed for removing calculus from the crowns of teeth. It emphasizes that sickle scalers should not be used on root surfaces. The text describes the triangular cross-section of the working end, which is suited for super gingival instrumentation. It provides a step-by-step guide on how to properly position the sickle scaler, maintain the correct angulation of 70 to 80 degrees, and use overlapping strokes when working on the anterior sextant, specifically the mandibular left central incisor. The importance of reassessing and correcting the practitioner's and patient's positions, as well as the grasp of the instrument, is highlighted throughout the technique practice.

Highlights
Sickle scalers are periodontal instruments used to remove calculus deposits from the crowns of teeth.
Sickle scalers should not be used on root surfaces.
The working end of a sickle scaler is triangular in cross-section, limiting its use to super-gingival instrumentation.
The sickle scaler has a pointed tip and two cutting edges per working end.
The face of the sickle scaler is perpendicular to the lower shank, ensuring the cutting edges are level with one another.
To establish correct angulation, the lower shank must be tilted slightly toward the tooth surface.
Technique practice with a sickle scaler is introduced on the anterior sextant, starting with the mandibular left central incisor facial aspect.
Correct positioning and grasp are essential for effective use of the sickle scaler.
The working end should be positioned near the midline of the tooth with a 70-80 degree instrument-to-face angulation.
Overlapping strokes should be used when working across the facial surface in the direction of the mesial surface.
