Introduction
This section is one of the criteria for dental rotating instruments.
This section contains modifications to the requirements for carbide finishing. The requirements for the needle for steel dressing remain the same.
The requirements for size and other requirements for the use of needles for car finishing and carbide finishing for car finishing as specified in this section are considered to be
It is important to ensure that these needles are interchangeably and safely used in dental clinics.
The nominal diameter of the working part listed in Tables 1 to 68 corresponds to the diameter specified in YY/T 1011-2014.
It should be noted that the YY/T 0783 standard gives a fifteen digital coding system for the division of all types of dental rotation
instrument.
