Polishing
how do you prevent overheating a tooth surface?
a WET polishing gent with MINIMAL pressure at a LOW speed to prevent overheating the tooth
Exposed Cementum or Dentin
Areas of exposed cementum (due to tissue recession) or exposed dentin should not be polished. Polishing removes significant amounts of these structures. Polishing should be limited to enamel surfaces.
What is two body abrasive polishing?
Involves abrasive particles attached to a medium Rubber cup
what are contraindications to polishing?
Lack of stain hypersensitive teeth exposed cementum or dentin restored tooth surfaces newly erupted teeth implant abutments dental caries gingiva that is inflamed areas of demineralization respiratory problems
what is extrinsic stains?
Not removed by scaling, Stains not etiologic factors for oral disease
Inflamed gingiva
Polishing not recommended for a patient with inflamed, enlarged, soft, spongy or bleeding tissue
Lack of Stain
cleaning agents will not cause the same potential damage NO ABRASIVE
areas of demineralization
conservation of demineralized enamel surfaces is indicated
what does splatter ?
consist s of airborne particles that land on people and objects
Implant abutment
metal or ceramic component that connects the implant crown to the implant fixture *YOU CAN POLISH THE CROWN ONLY*
a cleaning agent has
no abrasive
Discussion of stains
patient instruction/ education
Polishing splatter is composed of...
polishing paste, microorganisms, and saliva
what is bacteremia?
presence of bacteria in the blood
Restored Tooth Surfaces
restorative material are not as hard as enamel and therefore are scratched easily by abrasive pastes
What is tribiology?
science of interacting surfaces in relative motion it incorporates friction, lubrication, wear
newly erupted teeth
since the mineralization of newly erupted teeth is incomplete polishing should be avoided
Hypersensitive Teeth
teeth that are extremely sensitive need not to be polished If polishing is indicated a desensitizing formula may be used or toothpaste
dental caries
tooth decay*DO NOT POLISH*
True or False? scaling/ root planning will remove most stains
true
a cleaning agent does not polish
true
true or false coronal polishing can cause injury to the gingiva?
true
how long do microorganisms in dental aerosols survive for?
up to 24 hours
key principles of polishing
use light, intermittent pressure SLOW speed, SLOWEST sustainable speed Moist agent(polishing paste, also known as a prophy paste)
What is latrogenic?
used to describe a problem brought on by something that a clinician does
postponement of polishing
when oral hygiene instructions has not been provided or patient plaque control is inadequate soft spongy bone -- bleeds on brushing or gentle instrumentation after deep subgingival scaling and root planing -- not at same appointment, allow for healing. Abrasive particles can become embedded in periodontal pocket and interfere with healing active communicable diseases -- tuberculosis
what is three body abrasive polishing?
-Most commonly used by dental hygienist -Loose abrasive particles (the abrasive particles in prophylaxis polishing paste) move in the interface space between the surface being polished and the polishing application device (rubber cup or brush)
what is the is only positive effects of polishing ... improving appearance of the anterior teeth
Esthetics
a polishing agent has
an abrasive
what is dental aerosols?
are invisible airborne particles dispersed into the surrounding environment by dental equipment such as dental handpieces and electronically powered instrument.
respiratory problems
asthma or emphysema, lung cancer, cystic fibrosis, COPD
Adverse effects of polishing
environmental effects creation of bacteremia Damage to teeth
what is coronal polish?
is a technique that is used to remove plaque and stains from the coronal surface of the teeth.*NOT INVOLVING CALCULUS*
