What are the three specific parts of hand instruments?

The three specific parts of hand instruments are the handle, shank, and working end. The handle is the portion of the instrument that the clinician holds, and it is designed for ergonomics and control during procedures. The shank connects the handle to the working end and provides the necessary rigidity for the instrument to function properly. The working end is the part of the hand instrument that directly interacts with the tissue or material, performing the intended action, whether it be cutting, probing, or other functions.

Understanding these components is essential for recognizing how hand instruments are constructed and used in dental procedures. The handle, shank, and working end work together to create an effective tool for dental practice. Other choices reference terms that do not accurately describe the primary components of hand instruments in dentistry.
