Clinical Dental Hygiene Flashcards
used to penetrate soft tissue or bone should always be sterilized using heat
critical items
comes in contact with mucous membranes and non intact skin (skin that is abraded, chapped, dermatitis) should be sterilized using heat or disposable alternative
semi critical items
only contact skin (radiograph conehead, blood pressure cuff( clean with EPA registered hospital disinfectant
non critical items
direct touching saliva, blood, or OPIM
direct contact
touching something that is already contaminated
indirect contact
inanimate objects that when contaminated with infectious agents can transfer disease to a new host
fomite
visible particles of respirable size commonly generated by handpieces, ultrasonic scalers, air water syringe
aerosol
kills MOST organisms
disinfection
designed to kill all micro organisms including spores
sterilization
commonly used in dental offices, kills mycobacterium tuberculosis
intermediate
unacceptable in dental offices, kills hiv and hep b
low level disinfectants
steam autoclave
250 degrees F, 15-30 minutes
varies if instruments are wrapped or unwrapped
Recommended for all metal instruments
dry heat
Normal
Systolic <120, diastolic <80
Hypertension stage 1, 130-139/80-89
Hypertension stage 2, 140 or higher/90 or higher
Hypertensive crisis, higher than 180/higher than 120
Patients vitacall phls
loss of calcium, phosphate, and carbonate from the hydroxyapatite crystals
deminerilization
demineralization occurs when ph drops below critical levels —- to ——- for enamel, —- to —— for cementum
- 5-5.5
6. 0-6.7
involved in the caries process
acidogenic and aciduric
causes ph to fall and remain low
produce acids- lactic, butyric and propionic that dissolve tooth structure
bacteria
main species involved in caries and is gram positive
streptoccus mutans
what does streptoccus mutans mainly produce
lactic acid
found in large numbers after cavitation of tooth has occurred
lactobacillus
associated with root/cervical caries
actinomyces viscosis
fluoride is beneficial in halting the caries process as it has —–, that is slowly released over time, it interferes with bacterial metabolism- bactericidal or bacteriostatic
substantivity
evaluation of the relationship between the mesiobuccal cusp of the permanent max first molar and the buccal groove of the permanent mandibular first molar OR relationship of max and mandibular canines
angles classification
vertical overlap of max and mand incisors
overbite
horizontal overlap of max and mand incisors
overjet
relationship of the interproximal surfaces of the maxillary central incisors and the interproximal surfaces of the mandibular central incisors
midline deviation
first sign of gingivitis is
bleeding on probing
poor oral hyg. drinking dark colored beverages coffee tea fruit juices wine
brown
chx and stannous fl may not be able to remove
yellow brown
often found in healthy mouths, may be seen as thin lines on the cervical third of tooth, possibly caused by consumption of iron and insoluble ferric sulfide, gram +
black
poor oral hyg and chromogenic bacteria
green and yellow-green
poor oral hyg
orange
occupational exposure of metallic dust
blue green
