Similar to any other healthcare industry, dentistry too needs to follow strict guidelines in infection control. Regardless of the size of the dental practice, the infection control and disease anticipation is indispensable that plays an imperative role in the efficiency of the medical staff’s work, as well as the safety of dental practitioners and patients, by guaranteeing a sterile working environment that’s free of all types of infections.

Infection control includes proper sterilization and disinfection of the patient-care things and instruments. This step is basic to guarantee the instruments are free of perilous microorganisms that can cause infection.

Of all the strategies available for sterilization, moist heat within the form of immersed steam under pressure is the most widely utilized and the foremost reliable. Steam sterilization is innocuous, affordable, microbicidal; sporicidal, virucidal also penetrates fabrics.

The elemental rule of steam sterilization is to uncover each instrument to direct steam contact at the defined temperature and pressure for the required time. In this way, there are 3 parameters of steam sterilization: pressure, temperature, and time.

Pressure serves as a mean to get the high temperature vital to rapidly slaughter microorganisms. Particular temperatures must be obtained to guarantee the maximum effectiveness of sterilization. The two common steam-sterilizing temperatures are 121°C (249.8°F) and 134°C (273.2°F). These temperatures must be kept up for a particular time to slaughter microorganisms. At constant temperature the sterilization time may vary as per the sterilization type, temperature, wrapped or unwrapped instruments, etc.

Mode of Action:

Steam sterilizer devastates microorganisms by the irreversible coagulation and denaturation of enzymes and structural proteins. In the back of this reality, it has been found that the presence of moisture essentially influences the coagulation temperature of proteins and the temperature at which microorganisms are annihilated.

Types of Steam Sterilizer:

Since the ubiquity of steam sterilizers is continually on the rise, there is a tremendous array of products and types of steam sterilizers.

The two essential types of steam sterilizer (autoclave) used in dentistry are N-type (Gravity displacement autoclave) or B type (Vacuum Autoclave).



Type of load



Passive air removal from the Chamber ( Gravity displacement method) by steam

Unwrapped solid instruments

Simplest cycle. Inappropriate for sterilization of wrapped, hollow or porous instrument penetration into porous items is prolonged as improper air elimination

B type

Forced air removal utilizing a vacuum pump

Wrapped/unwrapped, Solid/hollow Porous/non-porous instruments

Ensure air removal from the chamber before the sterilization process. Immediate steam penetration to porous items. Effectively remove entrapped air in hollow & porous instruments

Hence, the most excellent dental autoclave is Class B autoclave because it can offer exceptional performance, magnificent effectiveness, and the most noteworthy possible safety measures.

The ultimate objective steam sterilization in oral healthcare offices is to diminish the rate of healthcare-associated diseases. When utilized legitimately, steam sterilizers guarantee the security of basic, semi-critical, and non-critical patient-care items. In case dental specialists entirely follow the rules of sterilization and infection control within the clinic, combined with the utilize of Class B dental autoclave, at that point the infection transmission will be minimized which encourages to make a secure environment for the patients and staffs.

  1. Thanks for this great and very important article on sterilisation in the dentist industry! It is an extremely hot topic right now with COVID-19 and all and the public doesn’t really know how dental offices make extra effort for staff and patient safety.
    Our local dental clinic in Preston in the UK have adopted similar technology and we are even experimenting with UV light disinfection technology as well (although it’s quite costly for us at the moment).
    Would be great to know if your supplier/provider gives you any certifications and case studies on the effectiveness of the steam approach? We have been receiving some requests for such and curious if you had a similar experience.
