Clinical DH, Fl and antimicrobials Flashcards
name regulated waste
sharps, items soaked in blood/saliva, hard and soft tissues removed from puts mouth
invisible, airborne particles, remain in the air for awhile
aerosol
visible airborne particles of blood/saliva, drop quickly to floor
spatter
kill/inactivate most pathogenic microbes, not spores
disinfectants
type of disinfectant, corrosive to metals, strong odor
chlorine based compounds
type of disinfectant, not corrosive, have ow kill spectrum, limited efficacy
quaternary compounds
type of disinfectant, should not be used as surface disinfectant because of toxic effects, also corrosive
Gluteraldehydes
level of surface disinfectant used in dental setting, must kill TB organisms
Intermediate
chemical spore test
Geobacillus stearothermophilus
dry heat spore test
bacillus atrophaeus
steam spore test
geobacillus stearothermophilus
do external indicators garnet sterility?
no- just that they have been heat processed
pt has decayed #30, ask about whitening. what do I dress first?
whitening
nutrient source for supra ging calculus
saliva
nutrient source for sub ging calc?
crevicular fluid and inflammatory exudate
stain- gram positive bactera, typically located on cervical 1/3 of facials and linguals
black line
stain- associated with poor dental hygiene and/or drinking dark colored beverages
brown
stain- associated with tobacco product use
darn brown and black
stain- chromogenic bacteria in plaque; associated with poor OH, mostly on ant. teeth
orange
can be associated with chlorhexidine use of stannous Fl, stannous Fl reaction is from reaction of tin ion in the FL
yellow brown and brown
associated with poor OH, chromogenic bacteria, fungi and gingival hemorrhage
green
early evidence of bone loss, instrument can enter the depression leading to the furcation
Class I (empty triangle)
moderate bone loss, instrument can enter furcation, but cannot pass between the roots
Class II (empty triangle)
sever bone loss, instrument can pass between roots
Class III (shaded in triangle)
same as class III, but evidence of recession
Class IV (shaded in triangle)
what probe is best for assessing furcations?
Nabers
Mobility. normal
1 or I
mobility. slight horizontal mobility
2 or II
mobility, moderate horizontal mobility greater than 1 mm, no vertical displacement
3 or III
demin beings at what pH for enamel
4.5-5.5
demin begins at what pH for cementum
6.0-6.7
fluoride interferes with ______
bacterial metabolism
in high concentrations (professional application), Fl is ______?
bactericidal
in low concentrations, Fl is _____?
bacteriostatic
who monitors the concentration level in community water fluoridation
EPA
who monitors Fl levels in bottled water
FDA
dietary Fl supplements recommended for who?
children who live in areas with not enough Fl, NOT PREGNANT WOMEN
Fl used in presence of tooth colored and porcelain restorations
Sodium Fl
contraindicated in presence of tooth colored restorations and porcelain, etches glass components causing surface roughening over time
APF
unstable solution, must be mixed fresh, bad taste, stains due to reaction of tin ion on FL (causes metallic taste), can cause ging sloughing
stannous Fl
if
administer Fl binding agent
if >5 mg/kg (toxic dose) of Fl is ingested you should
induce vomiting, administer Fl binding agent, seek medical tx
if >15 mg/kg (lethal dose) of Fl is ingested you should
seek medical tx, induce vomiting, cardiac monitoring
brush method. angle bristles 45 to apex at ging 1/3, bristles in sulcus
bass
brush method, angle bristles 45 toward apex w/ 1/2 bristles on tooth and other half on ging
stillman
use for open embrasures, exposed class IV furcation, ortho appliances, fixed prostheses, dental implant
interdental brush- inner wire must be plastic coated to avoid scratching cementum
use for open proximals, hard to access areas (3rd molars, crowded teeth), fixed prostheses
tufted brush
use for exposed class IV furcations, interdental cleaning (concave proximal areas), ging margins above ortho
tooth pick holder (perio aid)
use for interdental areas with recession
wedge stimulator
use for physically challenged, caregivers providing oral hygiene care
floss holder
use for under pontics of bridges or ortho
tufted floss
disrupts loosely adherent plaque and flushes debris/food particles around ortho
oral irrigator
active dentifrices ingredient for caries
Fl
active dentifrices ingredient for tartar control
pyrophosphates
active dentifrices ingredient for antihypersensitivity
potassium nitrate, strontium chloride, sodium citrate
active dentifrices ingredient for antibacterial
triclosan
active dentifrices ingredient for whitening
carbamide peroxide, hydrogen peroxide
where do you being stroke for scaling?
coronal to edge of junctional epithelium
Gracey used for mesial of post only
15/16
Gracey for distal of post teeth
13/14 or 17/18
what can you use for implant scalers
plastic, nylon, graphite, or gold tipped
what stroke does ultrasonic magnetostrictive produce
elliptical or orbital
what stoke foes ultrasonic piezo produce
linear
what stroke does sonic scaler produce
elliptical or orbital
most to least active part of ultrasonic
tip, concave face, convex back, lateral sides
how do ultrasonic scalers work?
cavitation
contraindications for ultrasonics
demin, exposed dentin, titanium implants, restorations, children with primary/new erupted teeth, dentures or communicable disease, respiratory conditions, diff swallowing, susceptible to infection
indications for rubber cup polishing
extrinsic stain
contraindications for rubber cup polishing
xerostomia, demin/decay, sensitivity, newly erupted teeth, severe gingivitis, lack of plaque/stain, exposed root surfaces, respiratory conditions
powder for air polishing
sodium bicarbonate, aluminum trihydroxide, glycine, calcium carbonate, calcium sodium phosphosilicate
indications for air polishing
stain/biofilm removal, root detoxification, sealant prep, soft debris removal around ortho
contraindications for air polishing
sodium restrcited diets, spongy ging, respiratory conditions, restorative materials, exposed root surfaces, immunocomprimised, puts taking potassium/anti diuretics/steroid
do you use pressure on pulp vitality test
no
bactericidal, high substantivity, .012%, stains teeth/tongue/tooth colored restorations, altered taste, irritates, increases supra calc formation
