Chapter 58: Coronal Polishing Flashcards
a procedure that removes plaque and stains from the coronal surfaces of the teeth
coronal polishing
Coronal polishing is completed with the use of these dental instruments
low-speed dental handpiece with a prophy angle
a rubber cup, and a polishing material
indications for coronal polishing
- Before placement of dental sealants
- Before placement of the dental dam
- Before cementation of orthodontic bands
- Before application of acid etching solution on enamel
- Before cementation of crowns and bridges
contraindications to coronal polishing
- no stain is present
- high risk for dental caries
- Sensitive teeth
- Newly erupted teeth
term for the portion of the tooth that is visible within the oral cavity
clicnical crown
commonly known as a prophy or a cleaning, is the complete removal of calculus
oral prophylaxis
a hard-mineralized deposit that is attached to the teeth) debris, stain, and plaque from the teeth with the use of hand instruments, ultrasonic scaling, and coronal polishing
calculus
Benefits of coronal polishing
-prepares the teeth for placement of dental sealants.
• Smooth tooth surfaces are easier for the patient to keep clean.
• Formation of new deposits is slowed.
• Patients appreciate the smooth feeling and clean appearance.
• Polishing prepares the teeth for placement of orthodontic brackets and/or bands.
a procedure in which only those teeth or surfaces with stain are polished.
selective polishing
The purpose of selective polishing is to avoid unnecessary removal of even small amounts of ___________
surface enamel
when should selective polishing be considered?
when the stain is very light and is not of esthetic concern to the patient,
The basic principle of selective polishing
teeth should not be polished unless it is necessary
polishing does NOT improve the uptake of professionally applied fluoride. Therefore polishing is no longer necessary before fluoride is applied.
T or F
true
refers to polishing of the root surfaces that have been exposed during periodontal surgery.
therapeutic polishing
Polishing reduces the _____ and the bacteria on the ______ .
endotoxins
cementum
Dental stains are categorized as
endogenous or exogenous
originate within the tooth through developmental and systemic disturbances. Types of these stains include those caused by an excessive amount of fluoride during formation of the tooth.
endogenous stains
stains that originate outside the tooth and are caused by environmental agents.
exogenous stains.
stains that appear on the exterior of the tooth and can be removed. Examples include staining from food, drink, and tobacco.
extrinsic stains
is a residue from the oral epithelium on the newly erupted enamel. This residue is easily stained from food and drink and can be difficult to remove with toothbrushing.
Nasmyth’s membrane
**it can be removed by SELECTIVE polishing of those teeth.
Thin black line on the teeth near the gingival margin. More common in girls. Frequently found in clean mouths. Difficult to remove.
Black stain
A very tenacious dark brown or black stain.
Caused by the products of coal tar in tobacco and by the penetration of tobacco juices into pits and fissures, enamel, and dentin of the teeth. Use of any tobacco-containing products causes tobacco stains on the teeth and restorations.
