Hand Hygiene is achieved by handwash, which is the primary means of infection control in dentistry infact any surgical procedure.
In Dentistry Hands are the parts of the body which are the most exposed to the site of operation, the site of operation is the place where chances of transmission of diseases is the maximum due to the exposure of the underlying structures during a surgery.
So Handwashing for a Dentist is the Primary necessity or the first step in achieving Infection Control.
Hand hygiene refers to the process for the physical removal of dirt, blood, body fluids and transient microorganisms from the hands (hand washing) and /or destruction of microorganisms (hand antisepsis). It is an important measure for preventing the spread of infection and is the cornerstone of good infection control. Direct contact is one of the main modes of transmission of Infectious Diseases.
When performed correctly, hand hygiene will remove transient microorganisms from the surface of the skin. For routine dentistry it is not necessary to try and remove the resident bacterial flora, which have a symbiotic protective role. However for surgical procedures (e.g Removal of a Impacted tooth) more extensive disinfection of the hands is required to reduce the numbers of resident bacteria.
