(Summary description)Sterilization refers to the measures that use strong physical and chemical factors to make all microorganisms inside and outside any object lose their growth and reproduction ability forever. Common sterilization methods include chemical reagent sterilization, ray sterilization, dry heat sterilization, moist heat sterilization and filtration sterilization.

Information

With the proper sterilization of instruments and materials, autoclave monitoring is an important part of any office infection control management plan.

Since various factors can determine the success of disinfection, it is important for dentists to regularly evaluate the efficiency of their office sterilizers. CDC and ADA recommend reviewing the operating procedures of the sterilizer with all personnel using the sterilizer, including packaging, loading and spore testing, to determine whether operator errors may lead to positive testing.

The following are some key recommendations that ADA and CDC should keep in mind when determining sterilizer monitoring procedures.

Sterilization monitoring best practices

Sterilization is the most effective monitoring when you use a combination of mechanical technology, chemical indicator cards and biological indicators.

Mechanical monitoring

Mechanical monitoring is achieved by analyzing the temperature, cycle time and pressure gauge / display on the sterilizer and recording the readings of each cycle.

Although accurate readings of these parameters may not ensure sterilization, incorrect readings may be the first indicator of cycle failure.

Chemical indicator

Use chemical indicators, such as internal or external indicator cards or tapes, with each sterilization load. These types of indicators will evaluate the physical conditions of the sterilization process and change color when exposed to the correct sterilization environment (such as time and temperature). However, unless a 5-level integral indicator is used, the chemical indicator cannot prove that sterilization has been achieved.

Biological indicators

According to the Centers for Disease Control and prevention, biological indicators are the most popular method to monitor the sterilization process. These indicators do not simply test the physical and chemical parameters of sterilization, but evaluate the sterilization process by actually killing highly resistant organisms such as Bacillus or thermophilic fatty bacteria.

You should verify the normal operation of the sterilization cycle by using the biological indicator regularly (at least once a week). However, when the load contains implantable devices, biological indicators should be used to monitor and isolate them until the results are obtained.

Types of biological monitoring

Office biological monitoring

Although office testing is a relatively new procedure for dental clinics, it has been used in hospitals for a long time. The office biological monitoring system usually includes spore test strip, culture tube and appropriate incubator system. If confirm 10 office biological monitoring system is used, the results will be given within 24-48 hours or 10 hours.

This is an ideal test method, especially when your office needs to test every day. For example, the CDC guidelines stipulate that biological indicators should be used to monitor each load containing implantable devices.

Email in biological monitoring

Postal monitoring services are one of the most cost-effective methods of using biological indicators to test sterilizers. When using this type of process, it usually takes 1 week to receive the sterilizer results. Although using email in the monitoring system takes longer to receive results, when you use a third-party monitoring program, it can provide higher credibility for your records than internal monitoring.

Some dental care professionals worry that the delay in the results due to the need to mail samples may lead to false negatives, but the study has determined that the delay has no impact on the test results.
