week 8

Question 1

what are 3 treatment strategies for gingivitis

Answer 1

biofilm removal
oral hygiene programs
Recontouring or replacement of defective or ill fitting restorations

Question 2

what are the 4 treatment strategies for periodontitis

Answer 2

• antimicrobial strategies to promote symbiosis
• management of host response to promote symbiosis (address modifiable risk factors for periodontitis)
• oral hygiene programs
• replacement of defective or ill fitting restorations to prevent plaque retention

Question 3

why is non surgical debridement the first phase of periodontal treatment

Answer 3

• it resolves inflammation - removes biofilm triggering host response
• directs host-microbial relationship back to symbiosis, balancing biofilm and promoting healing host response

Question 4

what is root planning

Answer 4

intentionally removes calculus deposits and diseased cementum leaving root smooth

Question 5

what is root surface debridment

Answer 5

removal of plaque and calculus without intentionally removing the pocket epithelium or cementum

Question 6

scalers

Answer 6

universal, two blades
supra gingival plaque stain and calculus

Question 7

universal curettes

Answer 7

two sides
supra and sub gingival

Question 8

site - specific curettes

Answer 8

one side only
Supra and sub gingival

Question 9

periodontal hoes chisels and files

Answer 9

multiple cutting edges
supragingival

Question 10

advantages of ultrasonics

Answer 10

more efficient - reduce operator fatigue
lavage effect for visibility
better access to furcations

Question 11

disadvantages of ultrasonics

Answer 11

leave a rough root surface

Question 12

what are the features of magnetostrictive ultrasonic scalers

Answer 12

20-40khz frequency
elliptical
metal rod
all surfaces active

Question 13

what are the features of piezoelectric ultrasonic scalers

Answer 13

29-50khz
linear
crystals activated by handpeice
only active on lateral sides

Question 14

are air polishes effective in removing calculus

Answer 14

no

Question 15

are airpolishes affective in removing stain and biofilm

Answer 15

yes

Question 16

why is it important to acheive a clean, smooth root surface at the end of debridment

Answer 16

rough surfaces increase plaque accumulation - easy to maintain

Question 17

what are the four factors influencing the complete removal of subgingival calculus in a periodontal pocket

Answer 17

-initial probing depth - over 5mm = increase probability of residual calculus
- tooth type - anterior teeth more debrided
- tooth surface - flat vs furcations
- experience of clinician

Question 18

what are the three components of supragingival plaque control

Answer 18

mechanical
chemical
behaviour modification of patient

Question 19

what are the two general methods for assessment of supragingival plaque control

Answer 19

lordal
Badersten

Question 20

cleaning aids for smooth and occlusal surfaces

Answer 20

manual and electric toothbrushes
end tuft brushes

Question 21

cleaning aids for interproximal surfaces

Answer 21

woodsticks
dental floss
waterpicks/irrigation devices
airflosses
interdental brushes

Question 22

modified bass technique

Answer 22

45 degrees - circular

Question 23

Fones technique

Answer 23

teeth are clenched
wide circular motion
good for children
not much cleaning of sulcus

Question 24

modified stillman

Answer 24

vibratory technique
from gingival margins down to incisal edges
used to be used after periodontal surgery

Question 25

leonards technique

Answer 25

vertical scrub technique - up and down
90 degrees to gingival margin
associated with gingival trauma and recession

Question 26

horizontal scrub technique

Answer 26

same as leonards but horizontal - side to side
commonly used by uninstructed adult patients
causes recession

Question 27

what would u use for a narrow embrasure space with intact papilla

Answer 27

dental floss
small interdental brush

Question 28

what would u use for moderate loss of papilla height with a medium embrasure space

Answer 28

interdental brush

Question 29

what would u use for wide open embrasure space with lost papilla

Answer 29

end-tuft brush

Question 30

what would u use for moderate papillary recession

Answer 30

dental floss

Question 31

How do we deliver clear oral hygeine instructions

Answer 31

clear with what we say
base instructions on individuals needs
listen to patients concerns- use as motivator
