Patient safety is an essential medical endeavour that focuses on improving patient care quality, reducing treatment mishaps, and increasing safety. The practice of Dentistry is not devoid of hazards. Pathogens can be transmitted between patients and the Dentist in a Clinical Setup, resulting in cross-infection. Infected air droplets, blood, saliva, and equipment contaminated with secretions can all Spread Dental Infection.

Despite the fact that Medical & Dental Societies, as well as governmental organizations, have issued numerous guidelines and recommendations, this blog will provide comprehensive information on infection control in Dental Practice through sterilization, as well as the criteria for selecting the right Autoclave.

Why dental Steam Sterilization becomes indispensable?

Dental Sterilization is beneficial not only to the health of others but also to the dental instrument's longevity. For the safety of patients, reliable and efficient infection control in a dental clinic is Necessary. The clinician must take the necessary steps to ensure that all instruments are properly washed before sterilization and that the process is performed in a safe way to Minimize the Spread of Infection.

Risks with Commonly Used Sterilization method:

In some areas, Dental Instrument Boilers & Top-Loading Autoclaves are available. Boilers are the most commonly used sterilization procedure; however, they are ineffective.

  • Boiler:

The mechanism behind this boiler is the water or the disinfecting liquid gets boiled with the help of electricity and it then cleans or disinfects the instruments kept. All the instruments like handpieces or cotton cannot be used for sterilization in this method.

  • Top Loading Autoclave:

Another method is using a Top-Loading Dental Autoclave. When the cooler surface of the instrument gets exposed to the steam generated inside the autoclave, it condenses and converts to water. This water creates a wet environment inside the chamber in which a few bacteria, fungi & up to some extent some viruses can be destroyed. But still, this is again an ineffective method of sterilizing all types of Dental Equipment.

  • Hot Air Oven:

This is electrically heated and has a blower to ensure that the hot air in the chamber is distributed evenly. It also has a thermostat that keeps the temperature of the chamber air at a set level. But it is a very time-consuming process with very little effectiveness & penetration to the sterilization of the Dental Instruments.

  • Chemiclave:

In a chemiclave, chemical vapour under pressure is used to sterilize items. However, some heat-resistant bacteria & viruses are unable to be sterilized in such an autoclave.

The Types of Dental Steam Sterilizers:

Moist heat, in the form of condensed steam under pressure, is the most often used and most successful method for sterilizing. Because of its penetration capacity, Steam Sterilization in Dentistry is more cost-efficient and effective than Dry Sterilization.

There are two types of steam sterilizers in the dentistry

  • N class Autoclave
  • B class Autoclave



N class Autoclave    

It sterilizes only Solid & Unwrapped Dental Instruments e.g. mouth mirror, probe, tweezer, forceps, etc.  Moist heat rushes from the sides of the sterilizing chamber thus pushing the air out of the chamber because of less weight of air compared to steam. Mainly used for sterilizing Non-porous and non-hollow instruments  

B class Autoclave   

All types of instruments - Porous or Non-Porous & Wrapped or Unwrapped Dental Instruments can be sterilized in a B class autoclave. The first vacuum cycle starts before the sterilization Process to remove the trapped air from the instruments, another vacuum cycle starts after sterilization to remove the moist air from the chamber and the last vacuum cycle at the end ensures 100% sterilization. 


Things to consider while choosing the right autoclave for your dental practice:

Now that you've learned about the many types of autoclaves on the market, it should be much easier for you to begin your research and make the best decision possible.

  • Instruments Type:

The type of instruments that needs to be sterilized. Solid instruments, hollow and porous instruments, etc. While a Class B Autoclave is unquestionably the finest option for a Dental Practice to sterilize the hollow & porous instruments, there are a few other factors to consider before making your decision.

  • Warranty:

Take into account the warranty, after-sales service and easy availability of trained technicians for regular servicing, and maintenance.

  • Capacity:

The larger volume, the more instruments it can take for sterilization at one time. If your practice is growing at a fast pace, it's better to buy an autoclave with a bigger capacity.

  • Brand:

It is better to choose an autoclave from a well-renowned brand and with established reliability which has a good reputation in the industry.

  • Advanced Options Availability:

Choosing an autoclave with a wide range of options can make all the difference. Autoclaves with USB tracking capabilities or options for temperature, pressure, and instrument type selection are available on the market, allowing the dentist to sterilize all sorts of equipment successfully. As in Runyes Feng 23L B Class Autoclave, the USB tracking facility is available along with the option for micro printer installation.
