name 7 qualitites of an ideal disinfectant:
|
1. broad spectrum-wide antimicrobial spectrum
2. fast acting-rapidly lethal on microorganisms 3. non-toxic-to operator; touch or inhaling 4. surface compatibility-not damaging to equipment and surfaces 5. easy to use-easy to mix or ready to use 6. residual effect-prolonged biocidal activity after application 7. odorless-non-offensive or no odor |
|
|
Levels of surface disinfectant ?:
commonly used in surgical areas as a disinfectant or sterilant |
high-
|
|
|
levels of surface disinfectant: ? unaccepetable in dental office; does not kill many microorganisms; quarternary ammonium compounds. iodophors, complex phenols.
|
low
|
|
|
levels of surface disinfectant?: commonly used in dental offices; should be EPA registered as tuberculocidal, hospital-grade and viurcidal; ability to kill Mycobacterium tuberculosis; chlorine compounds, iodophors, complex phenols
|
intermediate level disinfectant
|
|
|
_______: kills most microorganisms
|
disinfection
|
|
|
_____ ______-minimizes risk of puncture wounds; efficiently removes dried contaminants; can be used to clan dentures in a self-contained container
|
ultrasonic cleaning
|
|
|
_______: designed to kill all microoranisms, including spores.
|
sterilization
|
|
|
? method of sterilization: 20 minutes at 121 degree C and 15-30 psi. Variations in cycle depend on whether instruments are packaged and packing material-do not used closed containers, corrosion of non-stainless steel may occur, Bacilus stearothermophilus
|
steam autoclave
|
|
|
? method of sterilization: 20 min at 132 degree C and 20-40 psi-do not use closed containers, may damage plastic and rubber items, provide adequate ventilation, cannot sterilize liquids, Bacillus stearothermophilus spore test
|
unsaturated chemical vapor
|
|
|
? method of sterilization: 60-120 min at 160 degree C-cannot sterilize liquids, may damage plastic and rubber items, do not use paper products, recommened for metal instruments. Bacillus subtilis spore test
|
Dry heat
|
|
|
? method of sterilization: 10-16 hours at 61 degrees C- used for heat sensitive items, long turn-around time, requires adequate ventilation, Bacillus subtilis spore testing
|
Ethylene Oxide
|
|
|
____ tests- determine if autoclave is reaching proper temperature and pressure to kill all microorganisms
|
Spore tests
|
|
|
____ _____-turns brown once temperature is reached; does not determine sterility of instruments
|
indicator tape
|
|
|
____ _____: not present due to being extracted or congenitally missing: congenitally missing teeth are nothing to be concerned with, neeed to make patient aware of them.
|
Missing teeth
|
|
|
______ ______-have not erupted or are impacted
|
unerupted teeth
|
|
|
________-spaces between teeth; commonly caused by missing teeth, primate spaces
|
diastema
|
|
|
______-restores function to area where one or more teeth are missing; homecare of discussed in oral hygiene instructions
|
bridges
|
|
|
____ ______-restores function to area where one tooth is missing
|
dental implands
|
|
|
_____ ______-removal of pulpal tissues and replacement with endodontic material
|
root canal
|
|
|
_____-maxillary and mandibular teeth do not occlude
|
openbite
|
|
|
_______-maxillary teeth are positioned lingual to the mandibular teeth: commonly need to identify from intraoral photos.
|
crossbite
|
|
|
______-vertical overlap of maxillary and mandibular incisors; commonly need to identify from intraoral photos; deep overbite may cause indentation of maxillary lingual tissues.
|
overbite
|
|
|
_______-horizontal overlap of maxillary and mandibular incisors; may use probe to measure amount of overjet.
|
midline deviation
|
