air polishing Flashcards
WHAT IS AN AIR POLISHER?
- A specifically designed _______ that delivers a ________ spray or _______.
- Many different _______ systems:
__________, _________, __________ - ___________/power washer-like mechanism
- ________ abrasion
- ______ particles compelled by ________ air and _______ spray
- no _____________ against the tooth
A specifically designed HANDPIECE that delivers a CONTROLLED spray or SLURRY.
Many different DELIVERY systems:
HANDHELD, WIRED UNITS, GBT
SANDBLASTER/power washer-like mechanism
MECHANICAL abrasion
FINE particles compelled by COMPRESSED air and WATER spray
no hand pressure against the tooth
what does GBT stand for
guided biofilm therapy
- what does an air polisher do
- where is ours located in clinic
- removes HEAVY stain and biofilm when not using rubber cup polishing
- ours is wired and not on the bracket tray, must grab from sterilization
which powders/particles are for SUPRAGINGIVAL USE
which powders are for SUBGINGIVAL USE
SUPRA: sodium bicarbonate, aluminum trihydroxide, and calcium carbonate (very abrasive, injures the roots)
SUB: glycine-based powder and erythritol-based powder (less abrasive, doesn’t remove stain, just disrupts the biofilm)
what are the indication for supragingival air polishing (6)
- heavy extrinsic stain
- heavy biofilm
- soft debris/materia alba
- ortho (braces/brackets/wires)
- sealant preparation
- GBT (guided biofilm therapy)
what are the benefits for supragingival air polishing (7)
- rapid
- efficient
- removes less tooth structure
- latex allergy alternative (rubber cups)
- ergonomically better
- research supports use and benefits on dental implants
- less abrasive than traditional engine polishing when used correctly
what are the disadvantages to using air polishing
- more difficult to learn
- messy
- can’t use indirect vision (forced to sacrifice ergonomics)
- bitter taste and gritty texture for the pt
- soft tissue abrasion
- aerosols (the greatest AGP we perform)
what are the contraindication for air polishing
- SEVERE respiratory diseases (not early stages) EX- mod-sev COPD
- diseases associated with dysphagia (difficulty swallowing)
- end-stage renal disease (stage 5)
- patient wearing contact lens (have pt. remove)
- ACTIVE communicable diseases (tuberculosis/covid/flu)
- primary teeth (avoid those teeth if retained)
- sodium restricted diet (may need a specific type of powder - ALUMINUM TRIHYDROXIDE)
which polishing powders can be used on restorations
- subgingival powders: glycine-based and erythritol-based
- sodium bicarbonate can be used on amalgam, gold, and porcelain
which polishing powders can NOT be used on restorations
- sodium bicarbonate can NOT be used on hybrid composites, micro-filled composites, glass ionomers, compomers, or luting agents
- aluminum trihydroxide can not be used on ANY restorations
steps of the air polishing procedure (7)
- disinfect and apply barriers
- CONNECT AIR AND WATER LINES (air=gray; water=blue) and purge lines (2 minutes at the beginning of the day, 30 sec between pts.)
- fill powder bowl (shake powder well, follow manufacturer recommendations, don’t overfill, throw out extra powder after treatment)
- test powder to water ratio (create a slurry)
- test food pedal (full depression-slurry; half depression-water)
- set up HVE and grab a sterile tip
- prep your patient
parts of the cavitron prophy jet (7)
- main power on/off switch
- prophy mode auto cycles / manual mode
- tap-on wireless foot pedal
- powder flow control (H-L)
- diagnostic display
- handpiece holder
- jet-mate handpiece
what are the parts of the cavitron jet air polishing insert (5)
- insert heater rod (heats water for pt)
- prophy powder delivery tube (directs air/powder to tip)
- insert marking (label/identification)
- jet air polishing insert nozzle (tube in a tube)
- O-ring (seals the water- should be replaced when worn)
when air polishing:
______ cheeks rather than _______
_________ to the long axis of the tooth; center your spray in the ________ of the tooth
constant ________ motion; ____mm away from the tooth
CUP cheeks rather than RETRACT
PERPENDICULAR to the long axis/areas of the tooth; center your spray in the MIDDLE THIRD of the tooth
constant CIRCULAR motions; 3-4MM away from the tooth
what is the purpose of angulation of the tip
what is the angulation for buccal/lingual surfaces (posterior teeth)
what is the angulation for occlusal surfaces
what is the angulation for anterior surfaces
- TO AVOID TISSUE TRAUMA
- 80 DEGREE ANGLE TOWARD THE GINGIVA OF THE MOLARS/PREMOLARS
- 90 ANGLE TO THE OCCLUSAL SURFACE
- 60 DEGREE ANGLE TOWARD THE GINGIVA
do we point the air polisher into the sulcus?
when should you release the pedal to rinse?
- NO, “toward the gingiva” is just to determine the angle
- periodically every 3 teeth
how to reduce aerosols in the room
- HVE (standard/purevac)
what is the releaf for
water control only, does not control aerosols
how to address the messiness of the procedure?
how to make it less messy
- address the messiness by making a joke (bet you didn’t know you were getting a shower today as well at the office)
- work in a sequence, give pt paper towel, cup the cheeks dont retract, use HVE
after you finish polishing, what do you do?
- disclose to check yourself
- FLOSS
- end of the day procedure: purge, remove excess powder and dispose, remove nozzle and clean with wire, disinfect
when disinfecting the air polisher, can we spray it directly?
NO, DON’T SPRAY THE UNIT DIRECTLY! luckily we have wipes and don’t need to worry about spraying it
SUBGINGIVAL AIR POLISHING
- ________
- when used appropriately, can remove __________ from _______
- powders are less _______
- NEWER
- when used appropriately, can remove SUBGINGIVAL BIOFILM from ROOT SURFACES
- powders are LESS ABRASIVE
subgingival powders:
2: ___________ and ____________
___% less abrasive than _______
safe on ___________
__________ taste
GLYCINE and ERYTHRITOL POWDERS
80% less abrasive than SODIUM BICARBONATE
safe on RESTORATIONS
SWEETER taste
GUIDED BIOFILM THERAPY
A new wave of __________ care
reverses the order, explain
What might the benefits of this be? (2)
A new wave of sequencing care
from: assess, scale, air polish
to: assess, air polish, scale
benefits:
- Removes the biofilm to help us see the calculus
- Helps with assessment (some offices do air polishing, assessment, and scale)
does ODU use GBT?
NO
