Lecture 3: non-surgical therapy II Flashcards
abrasion depends on particle ______, _____ and ______.
hardness, size and shape
_______ is clinically effective in reducing plaque compared with _________.
triclosan (colgate total), fluoride dentrifrice
Triclosan inhibits _______.
PGE2
stannous fluoride has __________ effects, but causes _________.
anti-inflammatory, staining
active ingredients of listerine
essential oils (thymol, eucalyptol, methyl salicylate, menthol)
is listerine approved by the ADA to contol plaque and gingivitis?
yes
how does listerine work?
- essential oils (EO) exhibit broad spectrum activity against gr(-) and gr(+) bacteria
- disrupt bacterial cell walls
- reduce plaque endotoxin levels and pathogenicity
- can reduce plaque up to 56.3% and gingivitis by 35.9%
what are the active ingredients of CPC (Viadent)?
cetylpyridium chloride (CPC), zinc chloride
what is the active ingredient of CPC (cepocol)?
cetylpyridinum chloride
how does CPC work?
ruptures bacterial cell membrane causing rapid leakage of contents. may alter bacterial metabolism to inhibit cell growth
what is the active ingredient in peridex?
chlorhexidine gluconate
how does peridex work?
- alters permeability of cell membrane to cause leakage
- binds salivary mucins, reducing pellicle formation, which inhibits plaque bacteria colonization
- binds to bacteria, inhibiting absorption onto teeth
FDA has classified EO and CPC as _______.
safe and effective category 1
when are alcohol-based rinses contraindicated?
in alcoholics and children under 12
what does evidence say about alcohol-containing rinses and oral cancer risk?
