Effects of polishing: Bacteremia
~Condition the tissue before polishing
~ check medical history
~ Premed pts. that may be at risk(rheumatic heart disease, prosthetic valves, joint replacement, damaged heart valves)
what parts of the tooth should be avoided?
Cementum, dentin, and demineralized areas( nearly three times more surface enamel is lost from abrasive polishing over demineralized white spots than over intact enamel
Stain removal after gingival and perio treatments and scaling and root planing, is not recommended on the same day!!
What is recommended for newly placed restorations?
Remineralization of the surface with flouride is necessary after polishing the restoration.
A course abrasive may create a rougher tooth surface than before resulting in what?
Microorganisms collect and colonize on rough surfaces more rapidly than on a smooth surface
what is the effect on the gingiva?
~Removal of the epithelial layer(healing in 8-14 days)
~particles of a polishing agent can be forced into the subepithelial tissues and create a source of irritation
What are the effects on restorations?
Abrasive pastes can leave rough surfaces on various types of restorations including, gold, amalgm and composites
When should you postpone polishing?
When there has been no OHI yet, bleeding tissue, scaling and root planing, and communicable disease
What is contained in abrasive agents?
Silicon dioxide, pumice, calcium carbonate, tin oxide- metallic restorations, emery-aluminum oxide composites
What can be done to reduce aerosals?
Flushing lines 2 minutes before work and for 30seconds after each pt., preprocedural rinse, high volume evacuation, use of PPE, and eyewear for the patient.
Decribe the bristle brushes.
They can be pointed and flat for occlusal surfaces; slip-on screw-on or mandrel
What is tissue conditioning?
Teaching the patient the correct way to brush to prevent tissue from bleeding excessively while cleaning
what can polishing with a pumice for 30 seconds or more do to the enamel?
it can remove as much as 4 micrometers of enamel
What can create unnecessary sensitivity?
Removal of tooth structure in the cervical portion of the tooth, where enamel is thin and cementum is exposed.
(Thin enamel= ameliogenesis imperfecta)
What can removal of flouride rich surfaces result in?
* It can increase caries susceptibility
* Pts with xerostomia are more at risk
* apply topical flouride after polishing
* heat buildup (use light pressure, slow motion and moisture)
You should remove extrinsic stains not removed during toothbrushing and scaling. Name an example
Yhe black stain should not be polished because it has calculus like properties and it is commonly seen in children
Name some contraindications to polishing:
* rampant caries * Xerostomia
* thin enamel *sensitivity
* Demineralized areas
* Radiation
* repiratory problems
* composites and titanium implants
what are the principles for application of abrasives?
Use wet agents,
Apply a rubber polishing cup, using low speed,
use a light intermittent touch
Name the constituents of abrasives.
~abrasive: 50 -60% pumice silicon dioxide
~water; 10 -20%
~humectant 20-25% stabilizes glycerin
~binder 1.5-2% prevents separation agar
~flavoring and coloring agents
~flouride-minimal amount
Prophylaxis angle attachments:
Rubber cups are for removing stains and polishing restorations;
slip-on, screw on, mandrel mounted
made of natural rubber or can be synthetic
What is air-powder polishing used for?
Removes heavy tenacious stain
Name the advantages of the air-powder polisher.
uses air, water and sodium bicarbonate to deliver a controlled stream that propels specially processed particles to the tooth surface. Less time and exertion. Don't spray directly on gingiva or sulcus
what are the contraindications for air polishing?
*Physician directed sodium restricted diet
*Respiratory disease or swallowing prob.
*end stage renal disease
*communicable infection
*root surfaces exposed
*soft spongy gingiva
What is the porte polisher?
prophylactic hand instrument constructed to hold a wood point at a contra angle
what is the porte polisher used for?
removing stain, exposed cementum and hypersensitive teeth, titanium implants, periosurgery pts., hard to reach areas, infectious disease pts', application of desentizing pts'
what other uses are there for the porte polisher
Homebound, bedridden pts,small children, apprehensive pts, pts sensitive to vibrations
Clinical application of selective stain removal. Explain
~Scaling and rootplaning should be used to smooth the teeth, not polishing only.
~Don't polish when unnecesary
~Polishing should be based on the individual pts needs
