Which of the following is NOT considered a type of surgical instrument?

The toothbrush is not considered a type of surgical instrument because it is primarily a hygiene tool used for oral care and maintenance rather than a device designed for use in surgical procedures. Surgical instruments are specifically engineered to assist in performing surgeries or dental operations; they are essential tools that help in cutting, grasping, and suturing tissues in a clinical setting.

In contrast, the bone file, rongers, and surgical handpiece are all specialized instruments that play crucial roles in dental surgeries. A bone file is used to smooth bone surfaces, rongers are designed for tissue removal, and a surgical handpiece is utilized for drilling and shaping teeth or bone during surgical interventions. Understanding these distinctions is vital for recognizing the specific purposes and classifications of various dental tools used in practice.
