Calculus Removal Strokes Subgingival Calculus Deposits
TLDRThe video script provides a detailed demonstration on the proper technique for removing subgingival calculus using a Columbia Universal curette. It emphasizes the use of a biting stroke rather than a shaving stroke, with a focus on the 'toe one-third' of the curette for effective calculus removal. The process involves inserting the instrument subgingivally with minimal face and tooth contact, detecting the calculus deposit, and then using a short biting stroke with lateral pressure to dislodge the deposit. The importance of maintaining the correct angle of the instrument, between 70 to 80 degrees, is highlighted to prevent injury to the sulcus and ensure effective removal without burnishing the calculus. The demonstration aims to educate viewers on the meticulous and gentle approach required for safe and effective subgingival calculus removal.
Takeaways
- 🦷 **Use a Biting Stroke**: When removing subgingival calculus, employ a biting stroke rather than a shaving stroke.
- 🔍 **Zero-Degree Contact**: Insert the curette with minimal (near zero-degree) face and tooth contact to access the area.
- 🔨 **Locking the Toe**: Lock the toe one-third of the instrument onto the calculus deposit to effectively remove it.
- 🏠 **Subgingival Access**: The curette must be inserted under the gingiva to access and remove the calculus deposit.
- ⭕ **Universal Curette**: The Columbia Universal curette is suitable for both supra and subgingival use anywhere in the mouth.
- 📏 **Instrument Positioning**: Position the working end of the curette apical to the calculus deposit before locking on.
- 🔄 **Short Biting Stroke**: Utilize a short biting stroke with lateral pressure to dislodge the calculus deposit.
- 👆 **Fulcrum Finger**: Use the fulcrum finger to apply downward pressure while using the biting stroke.
- 📐 **Angle of Instrument**: Open the instrument to an angle of about 70 to 80 degrees when performing the biting stroke.
- ❌ **Avoid Full 90 Degrees**: Opening the instrument to 90 degrees risks injuring the sulcus by using the cutting edge.
- ✅ **Check and Repeat**: After the biting stroke, loosen the grasp and check if the deposit is removed; repeat if necessary.
Q & A
What is the main difference in technique between removing subgingival calculus and supragingival calculus?
-The main difference is that for subgingival calculus, a biting stroke is used instead of a shaving stroke, which is used for supragingival calculus.
What type of curette is recommended for removing subgingival calculus?
-A Columbia Universal curette is recommended, as it has a rounded toe that allows it to go subgingival and can be used anywhere in the mouth.
How should the face and tooth contact be positioned when inserting the curette under the gingiva?
-The face and tooth contact should be as close to zero degrees as possible to ensure proper access to the calculus deposit.
What part of the curette is used to remove the calculus deposit?
-The toe one-third of the working end of the instrument is used to remove the calculus deposit.
How should the curette be positioned to remove the calculus deposit?
-The curette should be inserted so that the toe one-third is positioned right above the calculus deposit, and then locked onto it.
What type of stroke is used to remove the calculus deposit after locking the curette in place?
-A short, biting stroke is used to pop the calculus deposit off after locking the curette in place.
Why is it important to ensure the grasp is loosened after the biting stroke?
-Loosening the grasp allows the practitioner to feel whether the deposit has been removed, and if not, to reapply the technique without causing injury.
What is the correct angulation to use when performing the biting stroke to remove the calculus deposit?
-The correct angulation is about 70 to 80 degrees to avoid injuring the sulcus or only shaving the top layer of the deposit.
What is the term used for when the calculus deposit is only partially removed and becomes more difficult to take off?
-This is called 'burnishing' the deposit, which makes it very difficult to remove.
Why is it important to use a fulcrum finger when applying lateral pressure with the curette?
-Using a fulcrum finger provides stability and control, allowing for effective removal of the calculus without causing damage to the tooth or gingival tissue.
What is the purpose of using lateral pressure when removing subgingival calculus?
-Lateral pressure helps to secure the curette against the tooth and effectively lifts the calculus deposit from the tooth surface during the biting stroke.
How does the technique described help prevent injury to the soft tissues of the mouth?
-By using a controlled biting stroke at a specific angulation (70 to 80 degrees) and ensuring minimal face and tooth contact, the technique minimizes the risk of injury to the gingival tissues and sulcus.

🦷 Removing Subgingival Calculus with a Columbia Universal Curette
This paragraph explains the process of removing subgingival calculus using a Columbia Universal curette, a tool with a rounded toe that can be used subgingivally. The key technique involves a biting stroke rather than a shaving stroke. To access the calculus, the curette is inserted with minimal face and tooth contact (close to zero degrees). The 'lock on' method is used where the toe one-third of the instrument is used to engage the calculus deposit. The deposit is then 'cupped' and removed with a short biting stroke, applying lateral pressure and using the fulcrum finger for support. The importance of angling the instrument to 70-80 degrees is emphasized to avoid injury to the sulcus or ineffective removal of the deposit.

Highlights
Removing subgingival calculus deposits requires a different technique than removing supragingival calculus.
Use a biting stroke rather than a shaving stroke for subgingival calculus removal.
The Columbia Universal curette is a universal tool with a rounded toe, suitable for subgingival and supragingival use.
To remove calculus deposits, insert the instrument under the gingiva with the face and tooth contact as close to zero degrees as possible.
Detect calculus deposits by inserting the back of the instrument under the gingiva.
Only use the toe one-third of the instrument's working end to remove the deposit.
Lock the toe one-third above the calculus deposit before applying the biting stroke.
Cup the calculus deposit and pop it off with a short biting stroke.
Push down on the fulcrum finger and apply lateral pressure with the instrument toe during the biting stroke.
After removing the deposit, loosen the grasp and feel for any remaining calculus.
If the deposit is not fully removed, repeat the process by locking the toe one-third above the deposit and applying the biting stroke.
Ensure the angulation is about 70 to 80 degrees when performing the biting stroke.
Avoid opening the instrument to 90 degrees as it may injure the sulcus.
Opening the instrument less than 45 degrees results in shaving the top layer of calculus, leading to burnishing.
Maintaining the correct angulation is crucial for effective calculus removal without damaging the tissue.
