polishing

Question 1

what can occur to patients during stain removal

Answer 1

hypersensitivity

Question 2

benefits if coronal polishing

Answer 2

prepares teeth for sealants
smooth surfaces
slows new deposits
stain removal

Question 3

air-powder polishing

Answer 3

a special designed hand piece with a nozzle that produces a high pressure steam of hot water and sodium bicarbonate

Question 4

rubber cup polishing

Answer 4

a rubber polishing cup slowly rotated with no water and the use of polishing paste

Question 5

most common form of polishing

Answer 5

rubber cup polishing

Question 6

polishing cups

Answer 6

soft webber polishing cups used to clean and polish the smooth surfaces of the teeth

attaches to the slow sped handpiece

Question 7

prophylaxis angle (prophy angle)

Answer 7

angle with a rubber cup and a bristle brush

Question 8

bristle brushes

Answer 8

used to do molars in the deep pits and fissures

Question 9

dental abrasives (polishing material)

Answer 9

used to remove stain and to polish natural teeth, prosthetic appliances, restos and castings

Question 10

5 kinds of dental abrasives available

Answer 10

extra coarse
coarse
medium
fine
extra fine

Question 11

what is the goal when choosing dental abrasives

Answer 11

to use the agent that produce the least amount of abrasion to the tooth surface

Question 12

5 characteristics of abrasive materials

Answer 12

shape
hardness
body strength
attrition resistance
particle size (grit)

Question 13

3 factors that influence the rate of abrasion

Answer 13

more agent used the greater degree of abrasion

light pressure= less abrasion

slower the rotation cup less abrasion

Question 14

what type of polishing paste should you use for esthetic restoration

Answer 14

diamond, aluminum oxide or low-abrasive tooth paste

Question 15

how many polishing strokes should be done per tooth

Answer 15

3-5

Question 16

shape of abrasives

Answer 16

irregular shaped particles with sharp edges will produce deep grooves

round particles will not abrade much

Question 17

hardness of abrasives

Answer 17

particles must be harder than the tooth

Question 18

what speed should be used while polishing

Answer 18

20,000 rpm

Question 19

abrasive body strength

Answer 19

particles that fracture into smaller sharp-edged particles

Question 20

attrition resistance for abrasives

Answer 20

effective abrasive particles do not dull or become embedded in the surface being abraded

Question 21

particle size (grit)

Answer 21

the larger the particle the more abrasive they are but have the least polishing ability

finer abrasives achieve a glossy finish

Question 22

what grasp is used for polishing

Answer 22

modified pen grasp

Question 23

fulcrum

Answer 23

an intra oral and extra oral finger rest used to provide stability to the operator

Question 24

when does a right handed operator usually begin when coronal polishing

Answer 24

8-9 o’clock

Question 25

when does a left handed operator usually begin when coronal polishing

Answer 25

3-4 o’clock

Question 26

why do you floss after coronal polishing

Answer 26

to polish interproximal tooth surfaces to remove any abrasive agent or debris that may be lodged in the contact area

Question 27

how may teeth away should your fulcrum be

Answer 27

maximum 4 teeth away

Question 28

what three criteria show that polishing is complete and well done

Answer 28

-no remaining stain or disclosing agent -teeth are glossy and reflect light from the mirror uniformly -no evidence of trauma to gums or other soft tissues

Question 29

disclosing agents

Answer 29

used to identify plaque or other soft deposits

Question 30

Six properties of an acceptable disclosing agent

Answer 30

- intensity of colour - duration of intensity - Taste - Must not be irritating to the mucous membrane - diffusibility - Must have antiseptic properties

Question 31

Three methods of application for disclosing agent

Answer 31

tablet Solution Rinse or mouthwash

Question 32

what should always be done before application of disclosing agent?

Answer 32

Evaluation of gingival tissues

Question 33

coronal polishing

Answer 33

A technique used to remove plaque and stains from the coronal surfaces of the teeth

Question 34

what surfaces can be polished?

Answer 34

lingual and buccal

Question 35

when should coronal polishing be done

Answer 35

after treatment for scaling, route planning, and other periodontal therapy the teeth are assessed for presence of stain

Question 36

effects on the teeth during coronal polishing

Answer 36

nearly three times surface enamel is lost from abrasive polishing grooves or scratches created the outer layer of enamel contains fluoride, this is stripped away

Question 37

do you polish a patients teeth with xerosromia, why

Answer 37

no because this patient cannot afford to lose any of their enamel

Question 38

heat production while polishing

Answer 38

the pressure and force can cause heat and irritation, use water to sooth teeth and slow motion

Question 39

3 reasons for stain removal

Answer 39

- if the stain cannot be removed by scaling - not necessary to polish before fluoride - contribute to motivation of the patient

Question 40

contradictions of polishing

Answer 40

-risk for caries -enamel problems -patients with tooth sensitivity -rampant caries

Question 41

contradictions that may need postponement of treatment

Answer 41

-When instruction for personal talk, removal has not yet been given -Soft, spongy tissue that bleeds on brushing or gentle instrumentation -Immediately following subgingival, scaling and root planning -Communicable diseases, potentially disseminated by aerosol

Question 42

2 environmental factors of coronal polishing

Answer 42

aerosol production spatter

Question 43

AGP

Answer 43

aerosol generating procedure

Question 44

selective polishing

Answer 44

A procedure in which only those teeth or surfaces with stain are polished to avoid unnecessary removal of even small amounts of the surface enamel
