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
|
|
|
Statement:
|
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 *restorations |
|
|
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 |
