Biofilm Control Strategies - Professional Flashcards
(25 cards)
What are examples of non-modifiable risk factors?
Age
Genetics
Systemic conditions e.g. pregnancy, leukaemia
Socioeconomic background
What are examples of modifiable risks which can be modified by a dentist?
- plaque and calculus removal
-well controlled restorations, crowns and bridges - well designed prosthesis
-improved anatomical features Hope contacts, malpositioned teeth, root grooves and con cavities)
What are examples of modifiable risk factors which can be de,at with by the patient?
Biofilm control/ oral hygiene practice
Tobacco use
Diabetic control Stress management
Diet (obesity, nutrition! Alcohol)
What is debridement?
Getting rid of debris I.e plaque
What attaches to the cementum in health?
Collagen fibres of the PDL
Cementum is exposed in periodontitis, True or False?
True
What can exposed cementum harbour?
Bacterial contaminants
How do you remove bacterial contaminants on cementum?
Removed with light instrumentation
What is the aim of non-surgical root surface debridement?
Remove or disturb the plaque biofilm
What is root surface debridement?
To remove supra-gingival plaque, calculus and staining
To debridement pocket over 4mm with subgingival deposits and BOP
When should you review root surface debridement?
8-12 weeks following treatment
What instruments can be used for root surface instrumentation?
Hand instruments
Powered scalers
What are the advantages of hand instruments for root surface debridement?
No aerosols
No heat generated
God tactile sensation
What are the disadvantages of hand instruments?
Requires correct angular ion of blade surface
Operator fatigue
Requires more time
Frequent instrument sharpening
What are the benefits of ultrasonic instruments?
Not much pressure
Simultaneous pocket irrigation
Requires less time
High patient acceptance
Less operator fatigue
Little soft tissue damage
No sharpening
What are the disadvantages of ultrasonic instrumentation?
Poorer tactile feedback
Highly contaminated aerosol
Possible risk for pt’s with pacemakers
Expensive
What are the types of hand instruments?
Scalers
Curettes
Hoes
What is the shank?
Can be simple or complex
What instrument is the scaler?
When would you use a scaler?
used for supragingival instrumentation or shallow pockets
Good for reaching interdental deposits at the gingival margin
what is the curette?
Come in a variety of shanks
When would you use a curette?
Subgingival scaling
Root turf ace debridement
Root surface smoothing
How many cutting edges does a hoe have?
1
When would you use a hoe?
heavy deposits of calculus
Usually restricted to supragingival scaling
