level questions: STERILIZATION

QuestionAnswer
Process by which all forms of life, including bacterial spores are destroyed by physical or chemical processSTERILIZATION
Process of destroying microbial life but not resistant bacterial spores thorugh the use of heat or chemical agentDISINFECTION
STEAM UNDER PRESSURE: temperatureTEMP: 121°C (250°F) and 132°C (270°F)
STEAM UNDER PRESSURE: how long at 121°C to sterilize in gravity displacement for rough instruments30 mins
STEAM UNDER PRESSURE: how long at 121°C to sterilize in gravity displacement for unrough instruments20 mins
STEAM UNDER PRESSURE (prevaccum sterilizer): rough4 mins
STEAM UNDER PRESSURE (prevaccum sterilizer): unrough3 mins
STEAM UNDER PRESSURE: Most common steam sterilization cycletraditional gravity sterilization cycle
TRUE OR FALSE: STEAM UNDER PRESSURE: you can use mineral waterFALSE
sterilizing porous loads or partially vented containers, where air cannot be easily displaced from an autoclave chamber, rendering gravity air displacement ineffective.Vacuum Sterilization Cycle
cages with animal bedding, wrapped goods, and surgical packsVacuum Sterilization Cycle
moist heat in the form of saturated steam under pressure is the most widely used and the most dependable.Vacuum Sterilization Cycle
nontoxic, inexpensive, rapidly microbicidal, sporicidal, and rapidly heats and penetrates fabricsVacuum Sterilization Cycle
Fast and dependable, non-toxic, no chemicals, antimicrobial, rapidly heats and penetrates fabricsVacuum Sterilization Cycle
DISADVANTAGES: Corrosion and combustion of lubricants associated with dental handpiecesVacuum Sterilization Cycle
DISADVANTAGES: reduction in ability to transmit light associated with laryngoscopesVacuum Sterilization Cycle
DISADVANTAGES: increased hardening time (5.6 fold) with plaster-castVacuum Sterilization Cycle
should be used whenever possible on all critical and semicritical items that are heat and moisture resistant.Vacuum Sterilization Cycle
UNSATURATED CHEMICAL VAPOR: heating a chemical solution, primarily ___________, in a closed pressurized chamber.alcohol with 0.23% formaldehyde
causes less corrosion of carbon steel instruments (e.g., dental burs) than steam sterilization because less water is present during the cycleUNSATURATED CHEMICAL VAPOR
This sterilizer is some as autoclave unlike it uses special chemical solution containing formaldehyde and alcoholUNSATURATED CHEMICAL VAPOR
UNSATURATED CHEMICAL VAPOR: The chemical vapour kills microorganisms by destroying ______-.vital protein systems
STERLIZATION CYCLE FOR CHEMICLAVE: TEMPERATURE IN CELCIUS132
STERLIZATION CYCLE FOR CHEMICLAVE: PRESSURE IN LBS20
STERLIZATION CYCLE FOR CHEMICLAVE: TIME IN MINS20

glassware, metal instruments, paper wrapped things and syringesPROLONGED DRY HEAT
PROLONGED DRY HEAT: TIME AND TEMP160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour
High Velocity Hot Air sterilisers time and temp190°C (375°F) for 6 to 12 minutes.
PROLONGED DRY HEAT: CONSIDERATIONItems should be dry
a medical treatment that utilizes light to activate a photosensitizing agent PS in the presence of oxygen.PHOTO ACTIVATED DISINFECTION
PHOTO ACTIVATED DISINFECTION: STERILIZES WHATRoot canal
forms of sterilizing monitoring:Involves physically looking at the gauges and readings on the sterilizer and recording the temperatures, pressure, and exposure time.Physical
forms of sterilizing monitoring:You can see the recordings, temperature, pressure, and exposure timePhysical
forms of sterilizing monitoring:Use of heat sensitive chemical; they change to colors when exposed to certain conditionChemical
types of chemical indicators:are placed on the outside of the instrument packages before sterilization.process indicator
types of chemical indicators:They respond to heat only.process indicator
types of chemical indicators:Aim to determine if the package processed or not; If not, sterilization is not achievedprocess indicator
types of chemical indicators:To simply identify the instrument that have been exposed to a certain temperatureprocess indicator
types of chemical indicators:instrument tape or color change marking indicators that do not measure the duration or the pressure, they only distinguished if the package is processed already or notprocess indicator
types of chemical indicators:are placed inside instrument packages, and they respond to a combination of steam and temperature and time.process integrator
