Perio Mastery Flashcards
Scaling vs root planing: Sub/Supraginvigal Removes what Stroke? Tools Treats what
Both can be sub or Supra
Scaling removes calculus and plaque, RP removes cementum
Scaling: wedging stroke, RP: shaving stroke
Tools:
Both: ultrasonics, curettes
Scaling: scalers
RP: files
Scaling treats perio/gingivitis
RP treats perio only
Non-surgical therapy aims to control infection by what 3 means
Altering subgingival ecology by disrupting biofilm
Reducing amount of bacteria
Suppressing inflammation
T/F complete removal of hard and soft deposits is a feasible objective of closed pocket root instrumentation
FALSE
Debridement:
instrumentation for removal of mineralized deposits (calculus)
Root planing:
Instrumentation to remove contaminated cementum and dentin in order to restore the biologic compatibility of periodontal diseased root surfaces
T/F calculus itself induces inflammation
FALSE, it provides an ideal surface for bacteria to stick to
Sickles main use
Debridement/scaling supragingivally or at tooth sites with shallow pockets
Hoes have _ cutting edges
Main use:
1
Supragingival scaling
Hand instrument most suitable for subgingival debridement
Curette
Angle a curette needs to be at when sharpening
70
Piezoelectric vs magnetostrictive scalers
P: electrical current causes linear vibrations
M: magnetic field causes elliptical vibrations
Pockets associated with what respond less favorable to non-surgical instrumentation
Molars (multi rooted teeth)
Furcation sites
Angular bone defects
Strengths of mechanical therapy (7)
Research Probe Depth Reduction BoP reduction Improvement in CAL Flora shift Low tech Safe
_% of Furcation are narrower than narrowest curette
58%
Reinfection can come from bacteria from where
Root surfaces not accessed
Gingival epithelial/connective tissue
Dentinal tubules
Supragingival plaque
4 parts to healing
Repair
Reattachment
New attachment
Regeneration
Scaler specs
Triangular
Flat
2 cutting edges
Sharp tip
Universal vs. specific curettes
Specific only has one cutting edge
Two scalers we use
Where are they used
204S
U15/30 T-J
Supragingival
Subgingival enamel
Near contact areas
NOT ON ROOT SURFACES
T/F local anesthesia is used with root planing
TRUE
Graces 3/4 is used where
All surfaces of anterior teeth
Mesial of premolars
Gracey 15/16 is used where
M/L/B of posterior teeth
Gracey 13/14 is used where
Distal of posterior teeth
Two universal curettes
Columbia 4R/4L
Younger-Good 7/8
Columbia 4R/4L vs Younger good
Both are universal BUT
Columbia: Interproximal
YG: Facial/lingual
Active tip area for 30 K frequency
50 K?
30: 4.2
50: 2.3
Thinner the insert, the _ the power
Lower
SPS
Sustained performance system
Blue zone
Lower power for subgingival scaling
