W8 Flashcards
what are 3 treatment strategies for gingivitis
biofilm removal
oral hygiene programs
Recontouring or replacement of defective or ill fitting restorations
what are the 4 treatment strategies for periodontitis
- 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
why is non surgical debridement the first phase of periodontal treatment
- it resolves inflammation - removes biofilm triggering host response
- directs host-microbial relationship back to symbiosis, balancing biofilm and promoting healing host response
what is root planning
intentionally removes calculus deposits and diseased cementum leaving root smooth
what is root surface debridment
removal of plaque and calculus without intentionally removing the pocket epithelium or cementum
scalers
universal, two blades
supra gingival plaque stain and calculus
universal curettes
two sides
supra and sub gingival
site - specific curettes
one side only
Supra and sub gingival
periodontal hoes chisels and files
multiple cutting edges
supragingival
advantages of ultrasonics
more efficient - reduce operator fatigue
lavage effect for visibility
better access to furcations
disadvantages of ultrasonics
leave a rough root surface
what are the features of magnetostrictive ultrasonic scalers
20-40khz frequency
elliptical
metal rod
all surfaces active
what are the features of piezoelectric ultrasonic scalers
29-50khz
linear
crystals activated by handpeice
only active on lateral sides
are air polishes effective in removing calculus
no
are airpolishes affective in removing stain and biofilm
yes
why is it important to acheive a clean, smooth root surface at the end of debridment
rough surfaces increase plaque accumulation - easy to maintain
what are the four factors influencing the complete removal of subgingival calculus in a periodontal pocket
-initial probing depth - over 5mm = increase probability of residual calculus
- tooth type - anterior teeth more debrided
- tooth surface - flat vs furcations
- experience of clinician
what are the three components of supragingival plaque control
mechanical
chemical
behaviour modification of patient
what are the two general methods for assessment of supragingival plaque control
lordal
Badersten
cleaning aids for smooth and occlusal surfaces
manual and electric toothbrushes
end tuft brushes
cleaning aids for interproximal surfaces
woodsticks
dental floss
waterpicks/irrigation devices
airflosses
interdental brushes
modified bass technique
45 degrees - circular
Fones technique
teeth are clenched
wide circular motion
good for children
not much cleaning of sulcus
modified stillman
vibratory technique
from gingival margins down to incisal edges
used to be used after periodontal surgery
leonards technique
vertical scrub technique - up and down
90 degrees to gingival margin
associated with gingival trauma and recession
horizontal scrub technique
same as leonards but horizontal - side to side
commonly used by uninstructed adult patients
causes recession
what would u use for a narrow embrasure space with intact papilla
dental floss
small interdental brush
what would u use for moderate loss of papilla height with a medium embrasure space
interdental brush
what would u use for wide open embrasure space with lost papilla
end-tuft brush
what would u use for moderate papillary recession
dental floss
How do we deliver clear oral hygeine instructions
clear with what we say
base instructions on individuals needs
listen to patients concerns- use as motivator
