1 - Infection Control Flashcards
what is the Intergumenatry system
It is the barrier system in which the skin, mucosa membrane and the teeth are included to protect the body from microbes
Name the main transmission of diseases in a dental office
Blood Saliva Aerosol Contaminated surfaces Contaminated instruments
What are the infections that can be transmitted in dental offices
Influenza viruses HIV/AIDS Hepatitis B Staphylococcus Herpes simplex type 1 Respiratory tract infections Rhinovirus Purulent streptococci
The transmission of the disease depends on 3 factors
Virulent pathogen, portal of entry and the host
Definition of asepsis
Preventing tissues and wounds from infection by decontamination of all that is in contact with them
Definition of antisepsis
Fights the infection inside the wounds
Definition of disinfection
Eliminating pathogenic microorganisms by chemical and physical means
Definition of sterilization
Eliminating all bacterial vegetative forms and spores on object ( instruments and surfaces)
Levels of disinfection
High level - kills all pathogen but not spores
Intermediate level - kills most pathogens except the resistant ones also not spores
Low level - unsecure risk of contamination
Agents that acts against cell membrane
Cationic detergents
Anionic detergents
Non - ionic detergents
Agents acting on functional groups of proteins and nuclei acids
Alkyl agents - substitutes unstable hydrogen atom with alkyl group
Oxidizing agents - oxidize sulfide groups and neutralize cells
Types of natural antimicrobial agents
Heat - moist heat and dry heat
Irradiation - ultraviolet light and electromagnetic radiation
Ultrasonic and sonic vibration
