Compressed air filters for dental practice

Is compressed air used in dentistry really clean?

In dentistry, compressed air is used to use equipment such as syringes and handpieces. Compressed air is blown into the mouth through this device. Compared to the size of pores in the human body, which are approximately 0.02 to 0.05 mm, the size of foreign matter contained in compressed air is very fine, approximately 0.0001 mm to 0.01 mm. have a size. The size of the foreign matter contained in the compressed air is much smaller than the size of the pores. As such, it is very fragile and susceptible to infection. If dirty compressed air is strongly sprayed on the gums, it can cause secondary infection as well as cerebral infarction in the long term.

Problems due to poor quality compressed air for dental treatment

  • 3-Way Syring (dental tools)

    Water, compressed air, water/air mixture can be sprayed in three ways Spray directly into the patient's mouth Contains high concentrations of heavy metals, bacteria, viruses, and fine dust -High-pressure spray on gums, skin, and pores (harmful substances can penetrate)
    -Concerns about serious disease infection such as bacterial infection and inflammation
  • Malfunction of medical tools due to poor compressed air quality

    3-Way Syringe, handpiece, etc. due to moisture in compressed air Prevention of aging, deformation and corrosion of consumable parts

Why is dental compressed air not clean?

The biggest problem is compressor location and poor management

It was written with reference to the Dental Compressed Air Quality Regulations of the American Dental Association (ADA).

During treatment, saliva, blood, and contaminated foreign substances sucked through the suction are collected in a machine room located in a corner and discharged through the sewage pipe. Contaminated air sucked in together remains in the machine room as it is. The compressor re-inhales and compresses the contaminated air, It is sent into the mouth, and eventually repeatedly compressed, sprayed, compressed, sprayed with contaminated air. So, of course, secondary contamination of patients can occur, and it can cause fatal risks to doctors and nurses who stay in the clinic for a long time. The American Dental Association recommends a compressed air moving distance of 10m or more, and has established management regulations for particles, moisture, and oil.

particle 0.005mm below moisture dew point 5℃ below oil 0.5ppm w/w below

Therefore, a compressed air filter must be used in dentistry as well. However, a general element filter generates differential pressure as it is used, Due to the discharge pressure much lower than the compressor input value, the failure of equipment such as handpieces is frequent.

Compressed air management case American Dental Association (ADA) - Since 1996, standards for infection prevention of compressed air for treatment have been established

  • Compressed air quality regulations

    dust(Foreign matter within 5㎛ in diameter), vapor(7 atm / dew point 5℃ or less), oil(oil 0.05ppm w/w) Ministry of Food and Drug Safety_HACCP (compressed air hygiene management plan) -Korea Food Safety Management Certification Agency: Periodic inspection for food manufacturers Compressed air quality inspection
  • Dental infection control standard policy manual

    The government's first attempt to standardize dental infection control -Environmental management and water pipe management (dental water) of dental medical institutions Although there are guidelines, there is no information on compressed air management used in dental treatment. no guidelines
