Benefits of field isolation (5)
1. patient protection/risk management
2. increased access/visibility
3. improved time efficiency
4. moisture control/improved quality
5. infection control
Additional benefit of field isolation
protection from accidental aspiration of small objects (dental burs, endodontic files)
Relative isolation (field isolation)
cotton rolls, guaze, saliva ejectors, HV suction, isolite, isovac, optragate, retractors, svedopter, hygoformic saliva ejector
absolute isolation
rubber damn
Are isolite/isovac and saliva ejectors enough to effectively reduce aerosols? can they substitute a rubber dam?
no
What instrument generated the most aerosols
high speed
Pre procedural rinse
reduces the number of microbes released into op envrionment.
Specs of mouth rinse
1.5% peroxide or .2% povidone should be used before any procedure for 30-60 seconds. No concreete evidence that it reduces infection, however
what percentage of airborne pathogens do rubber dams reduce? and with HVE?
70 and 90-98
Should the rubber dam cover the patients nose?
no
dental dam plastic frame
plastic nygaard ostby
dental damn metal frame
metal young design
can you demarcate the spot for tooth in rubber dam intraorally?
yes
rubber dam placement anterior teeth
canine to canine or premolar to premolar
rubber dam placement posterior teeth
one tooth distal and two teeth mesial to the affected tooth
one we use. spinning wheel hole punch
ainsworth design
no spin wheel
ivory design hole punch
perforations between the teeth should follow the tooth ______
long axis (lateral up and down). Follow tooth position of the arch (for crowding, hole punch based on how far up or back they are)
do you hole punch endentulous spaces?
no
what are the three types of clamps
winged, wingless, butterfly
two type of anterior clamps
212- wingless. small anterior and gingival retraction, flat jaw
9- winged. anterior offset flat jaws, stiff bow
There are 2 shapes for each type clamp (look up pic)
premolar clamps
#00, #0. winged, flat jaws and high bow. canines and premolars for 00, only premolars for 0
Winged molar clamp
#14A and 8a. deeply festooned jaws. for partially erupted molars
Wingless molar clamp
#26N and #27N. flat festooned jaws (27N particularly for second molars)
type of rubber dam clamp jaws (3)
flat, festooned, deeply festooned
what does a properly aligned clamp look like
prongs securely grasp the tooth at its four corners
foreceps you use in lab
stokes foreceps
ivory design clamp foreceps
the ones you saw as a DA
Techniques for rubber dam placement (4)
entire set, ingraham, clamp first, rubber dam first
entire set
rubber dam, clamp and frame placed at once
winged clamp used (#200, #14A, #8A)
ingraham technique
clamp and rubber dam placed then the frame
wingless clamp used (#26, #27N, #W8A)
REVIEW TECHNIQUE PPT
clamp first technique
clamp places then rubber damn with frame
wingless clamp used (#26, #27N, #W8A)
rubber dam first
rubber dam with frame placed first then the clamp
what should you do before placing a rubber dam?
prophy the teeth, check contacts with floss, move sharp edges from restoration, lubricate patient lips
In a winged clamp, what does the rubber dam sit on?
the wings of the clamp. Once placed. remove the rubber dam from ring and place around the ring
how do you clean the rubber dam and when
clean with 70% alchohol after placed and before the procedure begins
what is a ligature
floss tied around the teeth to help stabilize the rubber dam
what clamp do you use for single tooth isolation
butterfly clamp
special clams for gingival retraction
#212L and #212R
liquid dam
used for teeth whitening
common rubber dam mistakes
gingival tissue showing, tear at hole edge, clamp unable to hold rubber dam, floor sealing
result of poor sealing
gingiva is showing around the teeth or clamp, leakage of saliva/blood
