Introduction

Central compressed air source equipment is almost universally found in modern dental treatment facilities. It consists of components independent of the treatment room and is used to Compress air, prepare air that meets quality requirements and store dental air for pneumatic devices in the treatment room (such as pneumatic handpieces and three-way nozzles) gun) end use, as well as for cooling purposes.

Since the output of a central compressed air source device is used for dental treatment, the performance of the device as well as the quality characteristics of the air supplied to the dentistry are important.

is the subject of this document.

The requirements specified in this document are developed taking into account the requirements for air for dental use specified in YY/T 1043.2.

In medical applications, the quality of "medical air" is well defined. For example, there are similar definitions in the European Pharmacopoeia and other countries.

Medical air is used for artificial respiration, anesthesia, endoscopy and other in vivo applications, as well as for long-term treatment. In addition, it is used for sterile environment, such as the operating room. For these applications, a more precise definition of air quality is necessary. The European Pharmacopoeia gives airborne substances Content values and limits, as well as limits for hazardous pollutants.

In dental applications, compressed air is used to power treatment room pneumatic equipment such as pneumatic handpieces (drills) and to dry hands.

surgical site. The air used for these purposes is intermittently introduced into the patient's mouth and can, to a large extent, be rapidly expelled through dental suction equipment.

Since the ambient air in a dental treatment room is not sterile, there is no need to sterilize the dental air or to the substance content of the air used is controlled beyond the requirements of normal ambient air.

However, air used in dentistry has some basic quality characteristics.

a) Protect sensitive dental instruments and instruments (from oil, water, particles);

b) Provide clean and dry air to prevent dental surgery from being affected (because oil is a release agent and will affect oral adhesion systems such as system, etc.);

c) Prevent high humidity in the dental air from causing corrosion to air storage tanks and air ducts, and causing technical problems in dental instruments.

malfunction; also prevents the growth of microorganisms in dental air systems.

The test methods in this document were developed based on well-defined specifications for determining the quality of air for dental use.

So far, there is no international standard defining the quality of "dental air".

See Appendix A for relevant design examples of central compressed air source equipment.

See Appendix B for a suggested template for the test report.

Typical arrangements and construction and installation recommendations for central compressed air source equipment in dental facilities are provided in Appendix C.
