Approach to Disinfection and Sterilization.

In the clinic, we always have to do the disinfection and sterilization after or before we use the item because these process can help us to destroy the microbes and prevent transmit of the pathogens from instrument.

Cleaning means that only clean the visible spot with the water or detergent.Disinfection means that destroy most of the microbes but not including the bacterial spores.However,sterilization means that destroy all of the microbes including the bacterial spores.

Germicide is example of the agent which can destroy the microbes and divided into two parts:antiseptics and disinfectants.

Antiseptics use on the skin but disinfectant only use on the lifeless item.

We use the Spaulding classification to make the reasonable approach to disinfect or sterilize the clinic item.we can divided three parts:critical item which means that have high risk to infect,semicritical item which means that contact the mucous membrane or non-intact tissue,noncritical item means that contact the intact tissue

Also,disinfection and sterilization of the dental instrucment can follow Spaulding classification.

However, we don't have enough information to prove that  antibiotic-resistant bacteria have a little sensitivity to the disinfectant.

How about the surface disinfection??????surface infection refer to the noncritical item,so we also need to disinfect it but we don't have to use the high level disinfectant
