BY:JESSICA CHARLES INSTRUMENT STERILIZATION USED TO QUICKLY STERILIZE INSTRUMENTS. THE INSTRUMENTS ARE UNWRAPPED OR UNPACKAGED. WHICH IS A DISADVANTAGE BECAUSE WHEN THEY COME OUT OF THE STERILIZER THEY ARE NO LONGER STERILE. THE INSTRUMENTS THAT COME OUT OF THE STERILIZER SHOULD BE USED AS SOON AS POSSIBLE. THE ADVANTAGE OF THIS METHOD IS IT STERILIZES THE INSTRUMENTS IN A SHORT AMOUNT OF TIME. FLASH STERILIZATION CHEMICAL VAPOR STERILIZER THIS METHOD IS A LOT LIKE AUTOCLAVING, THE DIFFERENCE IS THAT THERE IS A MIXTURE OF CHEMICALS. THIS STERILIZER WILL NOT RUST,CORRODE OR DULL DRY METAL INSTRUMENTS, ALSO THERE IS A SHORT CYCLE TIME. IF YOU DON'T HAVE GOOD VENTILATION THIS STERLIZER CAN LEAVE AN ODOR AND CAN IRRITATE THE EYES LIQUID CHEMICAL STERLIZER THIS METHOD OF STERLIZATION STERLIZES INSTUMENTS THAT CAN'T WITHSTAND THE HEAT STERLIZER. STERILIZATION REQUIRES A TEN HOUR CONTACT TIME ANYTHING LESS IS NOT STERILIZED JUST DISINFECTED. THIS METHOD IS USED AT LOW TEMPERATURES WHICH IS GOOD FOR PLASTIC AND RUBBER INSTRUMENTS. THE DISADVANTAGE IS IT REQUIRES 4 TO 12 HOURS DEPENDING ON THE MODEL AND AT LEAST 16 HOURS AFTER STERLIZATION TO REMOVE THE GAS MOLECULES. THERE ARE MANY MORE DISADVANTAGES SUCH AS IT DOES NOT WORK WITH WET ITEMS, IT IS TOXIC IF THE GAS IS NOT HANDLED CORRECTLY. THE MAJORITY OF THESE STERLIZERS ARE USED IN LARGE HOSPITALS OR CLINIC BUT RARELY IN DENTAL OFFICES. ETHYLENENE OXCIDE STERILIZATION DRY HEAT STERLIZATION THIS METHOD WORKES BY HEATING UP AIR AND TRANSFERING THAT HEAT TO THE INSTRUMENTS.THE DISADVANTAGE IS THAT IT REQUIRES HIGHER TEMPERTURES THAN STEAM OR CHEMICAL STERILIZERS. THE ADVANTAGE TO THIS STERILIZER IS THAT THE INSTRUMENTS WILL NOT RUST AS LONG AS THEY ARE FULLY DRY BRFORE PLACING THEM INTO THE STERLIZER. THERE ARE TWO DIFFERENT TYPES OF DRY HEAT STERLIZERS. STEAM STERLIZATION STERILIZATION PREVENTS CROSS-CONTAMINATION OF DISEASES AND OTHER PATHOGENS TO PATIENT TO PATIENT. INSTRUMENT STERILIZATION IS INCORPORATED INTO THE DENTAL OFFICE BY ALL THE DIFFERENT METHODS OF STERLIZERS.MATERIALS THAT MAY BE USED IS STERILIZATION POUCHES, TOWELS FOR DRYING INSTRUMENTS, BRUSHES TO REMOVE EXTRA DEBREES. STERLIZING INSTRUMENTS IS ONE OF THE MOST IMPORTANT PARTS OF YOUR JOB FOR YOUR SAFETY AND FOR OTHERS. STEAM STERILIZATION IS THE MOST COMMON METHOD. IT IS NON TOXIC , RUNS A FAST CYCLE, KILLS SPORES AND IS INEXPENSIVE. THE DISADVANTAGES ARE THE HEAT CAN CAUSE DAMAGE TO DIFFERENT INSTRUMENTS ALSO THERE IS A LOT OF PRECAUTIONS WHEN LOADING THE STERILIZER LIKE IS THERE ENOUGH WATER IN THE STERILIZER, MAKE SURE IT IS NOT OVER LOADED, ARE THE PACKAGES OF INSTRUMENTS LOADED PROPERLY (OVER LOADING WILL NOT STERLIZE) AND ARE THE SETTINGS CORRECT ON THE STERLIZER.
