Chemical Plaque Control Flashcards
(22 cards)
How can chemical agents be classified?
Group A
group B
Group C
How can chemicals be used to control plaque?
Prevent adherence of bacteria
Prevention of multiplication of bacteria
Chemical removal of plaque
What are the features of group A agents?
Substantivity
Antibac
Anti plaque
CAN SUBSTITUTE MECHANICAL
Which agents are in group A?
CHX
Delmopinol
Salifluor
Acidified sodium chlorite
How does CHX work?
Dicationic Gold standards Bis bi guanine Anti bac Anti fungal
What percentage mouth wash do we give for CHX?
0.2%
Inhibits plaque
What effect does 1% have?
Cidal then static
What is the down side of CHX?
Altered taste and staining,parotid swelling,
By how much does CHX reduce plaque by?
50-90%
95% in five days
How does CHX damage the bacteria?
It’s is cationic to attracted to negative bacteria cell wall and disrupts it causing all components to leak out
How does Delmopinol work?
Anti adherent but Poorly retsined
It makes plaque matrix fall off the tooth has good efficacy
How does acidified sodium chlorite work?
Broad spectrum Antimicrobials, vital and fungal
Substantial similar to CHX
What is Goup B?
Little or no substantivity
Good spectrum
Some plaque inhibition
ADJUNCT
What are example of group B agents?1
Triclosan
Quarternary ammonium compound
Essential oils
Metal ions
How does Triclosan work?
Found in PLAX and COLGATE total Non ionic chlorinated bisphoenol Broad spectrum antibac and absorbed onto lipid cell wall Some anti inflam Reduces BOP and Pockeing
What are examples of essential oils?
Listerine: plaque reduction
What are example of the metal ions?
Stannous fluoride and zinc citrate
What are group C?
Antibac in Vitro
Moderate to low plaque inhibition
Not recommended
What are the group C compounds?
POSH F Povidine iodide Oxygenating agents Sanguinarine Hexitine
Fluorides
What is calculus ?
In organic compound of brushite followed by ortho calcium Phosohate and it contains HAP
What are anti calculus agents?
Crystal growth inhibitors: pyro phosphates, diphospjayes and zinc salts
Antimicrobials: Triclosan
Calcium lactate
How can you treat oral malodour?
Decrease VSC
Hydrogen peroxide, CHX, metal ions, Triclosan
