Coronal Polish Certification Practice Test

How should the right-angle handpiece be held during coronal polishing?

1. Palm grasp

2. Modified grasp

3. Pinch grasp

4. Pen grasp

The correct answer is: Pen grasp

The pen grasp is the correct way to hold the right-angle handpiece during coronal polishing because it allows for greater precision and control over the handpiece. This grip mimics how a person holds a pen, which provides stability and maneuverability while allowing for fine motor control. The dexterity afforded by this style of grasp is essential for navigating around teeth and ensuring that the polishing is performed accurately and effectively, particularly in tight areas and around dental restorations. In contrast, other grips, such as the palm grasp, may not allow for the same level of finesse or subtle movements, which are crucial in dental procedures. Similarly, the modified grasp and pinch grasp could limit the ability to effectively position the handpiece during the polishing process, leading to a less efficient and potentially less effective cleaning of the tooth surfaces. The focus with the pen grasp is on providing a stable yet delicate approach to ensure thorough and safe coronal polishing.
