Which dental handpiece is supplied with fiber optic light capabilities?

1. Low-speed handpiece

2. Electric handpiece

3. High-speed handpiece

4. Dental lathe

The correct answer is: High-speed handpiece

The high-speed handpiece is equipped with fiber optic light capabilities, which significantly enhances visibility in the oral cavity during dental procedures. This feature allows the clinician to see fine details while operating, improving precision when removing decay or preparing teeth for restorations. The fiber optic light is transmitted through the handpiece, illuminating the area directly, which is particularly beneficial in complex procedures where optimal lighting is crucial for success. Other types of handpieces, such as low-speed and electric handpieces, may not offer this integrated lighting capability. The dental lathe, on the other hand, is a machine used for polishing and adjusting dental materials and does not serve as a handpiece in clinical procedures. Therefore, the high-speed handpiece stands out due to its design and functionality in providing enhanced visibility through fiber optic lighting during dental treatments.
