YY/T 1755-2021 Dentistry—Powder jet handpieces and powders
Basic Information
Scope
This standard specifies the general requirements, test methods, manufacturer's information, marking, and packaging for air-driven sandblasting handpieces. The independently designed sandblasting handpieces are shown in Figure 1. This standard applies to sandblasting handpieces and sandblasting powders used in the dental field for removing dental calculus, stains, and plaque from patients' teeth. When used for cleaning and polishing teeth, abrasion is a side effect. This standard also applies to air-driven sandblasting handpieces and sandblasting powders used in the dental field for abrasion, such as the preparation of minimally invasive cavities, surface treatment before the application of adhesives, and the removal of water dams. In these cases, abrasion is an expected result. This standard does not apply to dental units that power sandblasting handpieces. This standard does not apply to dental polishing handpieces (angle handpieces), electric plaque removers (dental scalers), or multi-functional handpieces (spray guns).
