01 Scaling and root planing

Question 1

objectives of therapy

Answer 1

reduce gingival inflammation
eliminate pockets from elargement of gingiva
determine patient compliance

Question 2

rubber cup polish

Answer 2

rubber cup on prophy angle with abrasive polish to remove stain and plaque from exposed tooth and root surfaces

Question 3

scaling

Answer 3

instrumentation of tooth and root surfaces to remove plaque, calculus, and stains.
indications - calculus
remove calculus and reduce inflammation

Question 4

scaling rationale

Answer 4

calculus may prevent optimal oral hygiene and provide location for bacterial growth
studies show its effectiveness
better surgical tissue management in non-inflamed gingiva

Question 5

root planing

Answer 5

remove rough, calculus covered, or contaminated cementum or surface dentin
indications - rough or diseased root surface
remove affected surface, smooth surface

Question 6

root planing rationale

Answer 6

smooth surface reduces bacterial colonies
remove necrotic surface
healthy surface to promote reattachment
studies show its effectiveness

Question 7

adult prophylaxis vs periodontal prophylaxis

Answer 7

adult is preventative

perio is treatment in the presence of perio disease

Question 8

scaling instruments

Answer 8

scalers
universal curettes
site specific curettes

Question 9

scaler

Answer 9

supragingival calculus onlly
3 cutting edges
pointed toe
flat surfaces
blade curved in one plane
good for mand. anteriors

Question 10

universal curettes

Answer 10

2 cutting surfaces
semicircular cross section
round toe
curved blade in one plane
blade at 90degrees to shank
internal 70-80degree angle
one curette for all areas
both cutting edges used

Question 11

site specific curettes (gracey)

Answer 11

blade curved in 2 planes
blade 60-70degrees to shank
only one cutting edge used
use with shank parallel to tooth
thinner and lighter

Question 12

scaling instrumentation guidelines

Answer 12

good finger rests
tip into proximal
terminal shank parallel to long axis
handle angled to mesial
insert at angle then activate

Question 13

gracey 11/12

Answer 13

posterior teeth
cutting edge outside
M, F, L surfaces
shank parallel to long axis

Question 14

gracey 13/14

Answer 14

posterior teeth
D surfaces
cutting edge inside
shank parallel to long axis

Question 15

gracey 1/2

Answer 15

good for anterior
must identify cutting edge
shank parallel to long axis

Question 16

gracey 9/10

Answer 16

all anterior
often only for L surfaces
L, F of posterior teeth
must identify cutting edge

Question 17

universal curettes

Answer 17

M, D surfaces of posterior teeth
good for shallow furcations
lean towards tooth being scaled

Question 18

scaling difficult areas

Answer 18

specialized curettes
ultrasonics
rotary instruments
surgery

Question 19

sharpening instruments

Answer 19

sharpen only sides of blade
sharpen a little, often
maintain factory angle
