Coronal Polish Final Flashcards
Where and on who do you most commonly find black stain
Thin black line near gingival margin common on girls
What area of the tooth is coronal polish limited to when removing plaque and stain
Gingival third to incisal third (clinical crown)
Factors that affect abrasion
Amount of paste, pressure applied, rotation speed
What color are teeth affected by imperfect tooth development
Yellowish brown or gray brown (translucent or opalescent)
What happens with dentures during a polishing procedure
Kept in a wet paper towel to keep from distorting
Polishing procedure steps
Lifting wiping motion, flange prophet cup into sulcus, dry working area
Endogenous
Within tooth from developmental and systemic disturbances, excessive fluoride during formation, tetracycline
Exogenous
Outside caused by environmental agents
What is commonly used for cleaning and polishing of tooth surfaces
Abrasive zirconium silicate
Another name for dental fluorosis
Endogenous developmental stain
Sequence for coronal polishing
Disclose, polish, floss, disclose
What negative affect can course abrasive have
Create rougher tooth surface than before
Is abrasion greater with dentin or enamel
Dentin
Silex
Fairly abrasive used for heavy stains
Super fine silex
Light stains
Fine pumice
Mildly abrasive for persistent stains
Zirconium silicate
Doesn’t abrade used for polish
Chalk
Precipitated calcium carbonate combine with toothpaste and polishing paste
Commercial premixed
Variety of grits contain abrasive, water, humectant, binder
What is true of polishing and fluoride
Does not improve uptake of fluoride polish not necessary prior to uptake of fluoride
Where is yellow stain found and what causes it
Buccal surface of maxillary molars/lingual surface of lower anterior incisors poor hygiene
What stains are most commonly found on children
Green and nasmyth membrane
What damage can be caused from using prophy at high speed
Frictional heat, particles forced into sulcus, damage to gingival tissue
What are the recommended polishing pastes
High polish low abrasion
When are esthetic porcelain restorations polished
First
Where is green stain found and who most common
Kids and facial surface of maxillary anteriors
Polishing tips
Approx one cup polish for one or two teeth, moderate pressure, lowest handpiece speed, 20 psi air pressure
Where is supragingival calculus commonly found
Lingual of mandibular molars
What can home devices and brushes remove
Plaque, pellicle, materia alba
Evaluation of polishing
Reapply disclosing agent, teeth should be glossy and reflect light evenly, no evidence of trauma
What do you polish with when you use etch or bonding
Fine pumice
Techniques for using bristle brush
Soak in water, short stoke brushing from inclined plane to cusps
Bleeding or death causes discoloration
Pulpless teeth
Medication turns teeth green, yellow, gray brown
Tetracycline
White and brown spots
Fluorosis
Yellow brown/gray brown genetic abnormality
Imperfect tooth development
Gray or black
Silver amalgam
Yellow or green caused by jaundice and erythroblastosis
Systemic causes
Different ways discoloration can happen
Stain contained in calculus and soft deposits, incorporated with tooth structure, adhering to tooth surfaces
Air polishing
Delivers slurry of warm water and sodium bicarbonate under pressure
Powder mixed with water polishing agents
Powder abrasive mixed with water/mouthwash wet as possible to minimize frictional heat too wet=spatter
Proper patient position when polishing maxillary arch
Chin up operator between 8-12
What grit finishing strips are used on the proximal surfaces of anterior teeth
Fine
Where is a proper finger rest located
Same arch you are polishing close to working area intraoral or extraoral
What are cups made of for those with allergies
Synthetic materials
What type of polishing paste is recommended for filled hybrid composites and resin restorations
Low abrasive paste (micron-fine sapphire,diamond, aluminum oxide)
What are contraindications for diabetic patients
Disclosing products that contain iodine don’t need premed
Glossing after polishing
Use floss or tape for interproximal both types equally effective
Does polishing improve the uptake of professionally applied fluoride
No
Polishing of the roof surfaces that have been exposed during periodontal surgery
Therapeutic polishing
What areas should you avoid when polishing
Newly erupted teeth, expose cementum, demineralized areas
What type of handpiece is recommended for polishing
A low-speed with a maximum of 200,000 RPM
Intrinsic stains
Pulpless teeth, tetracycline, fluorosis, imperfect tooth dev, silver amalgam
