Most modern disinfectants inactivate viruses, but their effectiveness is greatly influenced by access and time of exposure: viruses trapped in heavy layers of mucus or fecal material are not inactivated easily. Viruses of different families vary greatly in their resistance to disinfectants, with enveloped viruses usually being much more sensitive than nonenveloped viruses. Disinfection of contaminated premises and equipment plays an important part in the control of diseases of livestock.

In Fenner's Veterinary Virology (Fifth Edition), 2017 Disinfectants and Disinfectionĭisinfectants are chemical germicides formulated for use on inanimate surfaces, in contrast to antiseptics, which are chemical germicides designed for use on the skin or mucous membranes. Finally, disinfectants will only be effective in a canal system that is sealed from oral fluids. Disinfectants are also more effective when the smear layer has been removed, in particular with disinfection of the exposed dentinal tubules. This is accomplished most effectively with NaOCl when the canal has been opened and shaped sufficiently to allow for a proper flow of irrigants apically and into irregularities. The ability of disinfectants to achieve their goals during root canal procedures is predicated on the removal of the gross debris in the canal system and the effective dissolution of the remaining pieces of tissue and fragmented predentin following canal shaping. Lovdahl DDS, MSD, FACD, FADI, in Problem Solving in Endodontics (Fifth Edition), 2011 What Is the Role of Disinfectants in Root Canal Procedures?ĭisinfectants are to be used to minimize or eliminate bacterial populations in the shaped root canal system.
