Which finger is typically used as a fulcrum while performing polishing?

Index finger
Middle finger
Third finger
Thumb

The correct answer is: Third finger

The third finger is typically used as a fulcrum during polishing because it provides stability and control to the handpiece while performing the procedure. When using the third finger as a fulcrum, it allows for a more precise and steady movement, minimizing the risk of slipping or applying excessive pressure on the tooth surface being polished. This positioning also helps in maintaining an ergonomic hand position, reducing strain during extended polishing sessions. Using the third finger helps in distributing force evenly, which can enhance the effectiveness of the polishing technique. Proper fulcrum placement is essential for achieving optimal results and preventing potential injuries or discomfort to both the patient and the operator.
