25
What should be professionally taught to patients?
Inter-dental cleaning, preferably with interdental brushes
26
What is the average plaque reduction with a manual toothbrush?
42%
27
What is the average plaque reduction with an electric toothbrush?
46%
28
What are the recommendations from 11th European Workshop (2015)?
Brush twice a day for 2 minutes
29
Who is 2 minutes of brushing likely to be insufficient for?
Periodontitis patients
30
How often should patients use interdental cleaning?
Once every 24 hours
31
What are the different types of interdental cleaning?
Flossing, interdental brushes, woodsticks, and oral irrigators
32
What are the most effective devices to remove interdental plaque?
Inter-dental brushes
33
What is needed to make flossing effort worthwhile?
Proper instruction, sufficient motivation of patient, and a high level of dexterity
34
What are the benefits of single tufted brushes?
BoP eliminated, PPD reduced by mean of 1.8mm, and periopathogens reduced 14% to 0.8%
35
What are the other constituents of mouthwashes?
Solubilisers, flavourings, preservatives, alcohol, water, colourings, SLS, foaming agents etc.
36
What are co-adjunctive chemicals?
Mouthwashes
37
What are the 3 main categories of mouthwash?
Those for use against halitosis (cosmetic), those advocated to reduce plaque bacteria (and hence adjuncts against periodontal diseases) (chemo-therapeutic), and those advocated for prevention and repair of dental caries (chemo-therapeutic)
38
What mouthwashes are advocated to reduce plaque bacteria?
M/Ws containing chlorhexidine gluconate (e.g., Corsodyl), essential oils (e.g., Listerine), and cetylpyridinium chloride/CPC (a quaternary ammonium compound) (e.g., Eludril, Plax)
39
What mouthwashes are advocated for prevention and repair of dental caries?
M/Ws containing fluoride
40
What do some mouthwashes have?
Both anti-plaque and remineralisation active ingredients
41
What is chlorhexidine generally regearded as?
An ‘antiseptic’ rather than an antimicrobial
42
What are the properties of chlorhexidine?
Bacteriostatic (inhibits growth) and bactericidal properties (kills bacteria)
43
What type of molecule is chlorhexidine?
A positively charged molecule that binds to negatively charged sites on cell wall
44
What does chlorhexidine do to the bacterial cell wall?
It destabilizes cell wall and interferes with osmosis, ultimately leading to lysis
45
What is the mode of action of chlorhexidine in topical applications?
Shown to have unique ability to bind to proteins present in human tissues such as skin and mucous membranes with limited systemic/bodily absorption
46
What is the substantivity of chlorhexidine?
Released slowly leading to prolonged activity
47
What does chlorhexidine have cidal actions againt?
Fungi (Candida) so has uses in treatment and prevention of denture induced candidosis
48
What is the concentration of chlorhexidine original?
0.2%
49
What is the concentration of chlorhexidine daily?
0.06%
50
How long should you use chlorhexidine original for?
2 weeks
51
What are the adverse effects of chlorhexidine?
Taste disturbance/alteration, effects on oral mucosa including soreness, irritation, mild desquamation and mucosal ulceration/erosions and a general burning sensation/a burning tongue/both
52
What are the four essential oils?
Eucalyptol, thymol, methyl salicylate and menthol
53
What are essential oils?
Antibacterial antiplaque agents, and have ability to penetrate biofilm
54
What are some of the proposed methods of action of essential oils?
Disruption of cell membranes, perturbation of proton pumps, and coagulation of cell content
55
What does the Listerine range also contain?
Fluoride (anywhere from 100 to 450 ppm)
56
What do essential oil containing mouthwashes kill?
A broad spectrum of planktonic bacteria and penetrate biofilm, allowing action upon sessile (within matrix) bacteria
57
What is the optimum concentration of NaF in fluoride containing mouthwashes?
0.05% (or approx. 225ppm)
58
How is triclosan thought to primarily function?
By inhibiting fatty acid synthesis (in bacterial rather than human cells)
59
What is triclosan bacteriostatic in?
Concentrations used in toothpaste formulations
60
What is triclosan biocidal in?
Higher concentrations
61
What is the definition of biocidal?
Destructive to life
62
Why has triclosan been phased out?
Not environmentally friendly
63
What are the risk factors of periodontitis?
Genetics, stress, smoking, drugs, diabetes, and pregnancy
64
How should smoking cessation be given?
ASK, ADVISE, ACT
65

Are you a smoker?

What is ADVISE?
On benefits of stopping and best methods
67

Motivate and refer
