Low level disinfection possesses narrow antimicrobial activity. Intermediate level disinfection involves destruction of microorganisms like tubercle bacilli but not able to kill spore. High level disinfection involves bacterial spore inactivity along with other microbial forms. Disinfection can be divided into three categories according to their efficacy. While sterilization is the complete elimination of all micro-organisms including spores. Disinfection is the process that eliminates many to all pathogenic microorganisms on inanimate objects except bacterial endospores. blood, saliva, debris) from objects while decontamination is the removal of pathogenic micro-organisms from objects. 1 Cleaning is the removal of all foreign material (e.g. In order to avoid the spread of pathogens from patients to patient, patient to health care personnel and health care personnel to patient, it is the duty of the health care policies makers to allocate the appropriate methods of cleaning, disinfection and sterilization for various surfaces and instruments. Disinfection and sterilization methods are used to achieve disinfection and sterility of the medical and surgical instruments. The importance of cross-infection control cannot be overemphasized. Received: 27 July 2018, Accepted: 02 August 2018 INTRODUCTION An overview of dental impression disinfection techniques- a literature review. It will also provide knowledge about mechanism of action, concentration of usage along with commercial preparations available of different disinfectants. In order to enhance the knowledge and improve the behavior of dental health care workers about impression disinfection, a structured literature review of the current disinfection techniques has been carried out. Various methods of impression disinfection have been described in literature having their own advantages, disadvantages and effects on impression material. The most effective way to prevent their spread through dental impression is to make the impression sterile just after coming out of mouth. Hepatitis B, C, HIV, Mycobacterium, Herpes simplex, Ebola, MERS-CoV etc. Dental impressions can act as vehicle for various types of micro-organisms E.g. 15min.Ġ.24g Benzyl-C12-16-alkyldimethylammonium chloride, 0.24g N,N-didecyl-N,N-dimethyl ammonium chloride, 0.24g C12-14-alkyldimethyl ammo- nium chloride, 0.35g chlorhexidine gluconateĭirective 648/2004/EC: Contains < 5% cationic surfactants, fragrance. terrae in a suspension test, low contamination): Conc. 1min., Candida albicans as per VAH, EN 13624 and EN 14562 (high contamination): Conc.

Only immerse alginates and hydrocolloids for a short time and let them dry. The impression must be fully covered by the solution. Immerse the respective impression into the ready-for-use disinfectant solution, and remove again after the recommended application time. For Disinfection of Dental Impression Materials
