Sterilization is the procedure of abolishing all the micro-organisms present on the surface of any instruments, either they are pathogenic or non-pathogenic, whether in spore form or in vegetative form. When any of the object that is carried in the process of sterilization and after it is being free from all the living beings, is known as a sterile object.
For a dental clinic it is very important to carry out the sterilization on a regular basis for all the reusable instruments. The most effective method for dental instruments sterilization is steam under pressure technique. This kind of sterilization can be achieved by the use of an autoclave sterilization procedure in a dental care office.
Autoclave Steam Sterilizer Machine is usually used for healthcare system. An autoclave is a machine that devastates dangerous microorganisms, virus, Fungi and spore on dental instruments that are put within a high pressure chamber by using steam.
This autoclave can be categorised into Top loading autoclave or front loading autoclave as per the dentist’s requirements.
Steam Sterilization of dental instruments are effective on all of the living microorganisms as steam has a greater efficacy to kill the vegetative as well as the spore form of the living organisms.
History of Dental Autoclave:
Autoclave is the combination of two different words, “Auto” means self in Greek and “Clavis” means locking device in Latin. Autoclave was invented by French Microbiologist Charles Chamberland for medical use in 1879. New autoclave Technology e.g. pre-vacuum cycle in 1958 and steam-flush pressure in 1987 were introduced for use in healthcare industry.
Working of Sterilizer Machine:
The used dental instruments are placed inside the chamber. The items to be autoclaved are subjected to high temperature and high pressure. The process is as below:
- Distilled water boils to form steam in high temperature
- Pressure also increases inside the chamber
- Saturated steam has penetrating capacity
- Items to be sterilized should be kept separated inside the chamber for proper penetration and sterilization
- Irreversible denaturation of enzyme and structural proteins of microorganisms lead to destruction when exposed to steam under pressure in autoclave
- After sterilization the steam is removed from the chamber and depressurization occur for the items to get dry
- Items are now autoclaved to be used further
Advantages of Autoclave Sterilization:
- Most effective decontamination method for healthcare industry
- Fastest sterilization with short cycle time
- Good penetration capacity for effective sterilization
- Easy to operate
- No specific chemicals required
Types of Autoclave:
In dental profession there are different kinds of autoclaves that are being categorized and used according to the need of the professionals. They are
- Class N Autoclave
- Class B Autoclave
N-Class Autoclave: N class autoclave are meant for the sterilization of solid naked instruments only as no vacuum cycle is there. No wrapped, porous, hollow instruments can be sterilized in this N class autoclave. Some N class autoclave has dry cycle for the items to be air dried with semi-open door.
B-Class Autoclave: Class B Autoclave is an advanced autoclave with Triple vacuum cycle for an effective sterilization of all wrapped/unwrapped, solid/hollow, porous/non-porous instruments. All dental handpieces, implant kits can also be sterilized in this autoclave without compromising the efficiency of the equipment's. Some B class autoclave also come with B+ Cycle with increased sterilization time that is also known as Prion cycle. (Runyes Feng 23 B class autoclave come equipped with B+ cycle to help implantologist in high effective sterilization of implant kits).
Dental Autoclave is an essential dental practice office as it can protect the patients as well as the operator from horizontal contamination of the infections. There are different autoclaves from different manufacturers are available in the market.
