Old vs. New Desident 1. 2. 3. 4. 5. Old Desident did not have virucide effectiveness. New Desident Cavicide has a completely new chemical composition so the product is also effective against viruses. There is no similarity between the old and the new one in chemical composition. Old Desident had a very high content of alcohol in the formula – over 80%. New Desident Cavicide has alcohol content of 17.5%. For more information on Desident CaviCide please see remaining slides of the presentation. Desident Cavicide is recommended for use on nonporouse surfaces only. Desident® CaviCide New disinfectant/decontaminant cleaner with wider effectiveness Hierarchy of resistance • Bacterial spores - Bacillus subtilis • Mycobacteria - Mycobacteruim tuberculosis • Nonlipid or small viruses (Non enveloped) Polio virus • Fungi - Trichophyton spp. • Vegetative bacteria - Pseudomonas aeruginosa, Staphylococcus aureus • Lipid or medium-sized viruses - Herpes simplex virus, hepatitis B virus, HIV Desident Cavicide Intermediate - Level Disinfectant • Between patients • Counter tops, dental unit surfaces • Intraoral items going to + coming from lab. – Bite registrations, restorations, A-silicone impressions – Prosthetic, ortho. appliances • Clean first – Spray – Wipe – Spray Desident® CaviCide • Broader effectiveness: Bactericidal Virucidal Fungicidal Tuberculocidal • Disinfectant, decontaminant and cleaner all in one • Compatible with most medical devices material • For use on nonporous surfaces, even in neonatal and infant care areas • Nontoxic and nonirritating • Low alcohol content – 17.5% Desident® CaviCide Is a Low alcohol solution High % Alcohol Solutions are considered if alcohol content is over 22% (like old Desident with alcohol content over 80%) Disadvantages of high alcohol solutions: • Damage surfaces, equipment • Desiccate: adhere (fix) bioburden to surfaces • Evaporate rapidly: reduced contact time • Are ineffective pre-cleaners – must use other product to clean first • Should be disinfectants (only step 2) Desident Cavicide EFFECTIVE AGAINST • Mycobacterium tuberculosis var: bovis (BCG) • Staphylococcus aureus 3 min. • Pseudomonas aeruginosa • Salmonella enterica • Trichophyton mentagrophytes • Clostridium difficile (vegetative cells) • Methicillin Resistant Staphylococcus aureus (MRSA) • Vancomycin Resistant Enterococcus faecalis (VRE) • Staphylococcus aureus with reduced susceptibility to vancomycin • Hepatitis B Virus (HBV) 2 min. • Hepatitis C Virus (HCV) • Herpes Simplex Virus Types 1 and 2 • Human Immunodeficiency Virus (HIV-1) • Human Coronavirus • Influenza A2 Virus HOW TO PROCEED?
