What dental instruments are more commonly referred to by number than by name?

In dentistry, several instruments are commonly referred to by their numbers rather than their names, including the #2 and #4 handpieces, which are used for various types of dental procedures. The #15 blade is frequently used in oral surgery for incisions, while the #11 blade is often utilized for making precise cuts. Additionally, the #5 and #6 explorers are used for examining teeth and detecting cavities. These numeric designations help streamline communication among dental professionals.
