The primary purpose of the Fiberoptic High-Speed Handpiece is to illuminate the tooth during preparation for restoration. This specialized dental instrument integrates fiber optics, allowing for enhanced visibility while performing procedures. The illumination helps the dentist see the operating area more clearly, which is crucial for precision and accuracy in dental work, especially during intricate restorative procedures. This improved visibility can lead to better clinical outcomes, as the dentist can identify decay, examine the margins of restorations, and ensure thorough tooth preparation.

The handpiece's high-speed capability allows for efficient cutting of enamel and dentin, which is essential during procedures such as cavity preparation. However, the primary enhancement this tool offers is the ability to illuminate the field of view directly, making it easier for the dental professional to see what they are working on without straining to look around shadows or rely on external lights.
