The following is the mechanism of action is used for what mouthrinsing agent?
deposit FL ion on enamel of carious lesion
The following is the mechanism of action for what mouth rinse?
deposit FL ion on enamel of carious lesion and has a tin ion that interferes with cell metabolism for antimicrobial effect
The following mechanism of action is used for what mouth rinse?
inhibits demineralization and enhances remineralization
The follwing is the mechanism of action for what type of mouth rinse?
cationic bisbiguanide with antibacterial ctivity binds to hard and soft tissues - damages cytoplasm of cell membrane (bacteriocidal); binds to pellicle to prevent biofilm accumulation; bacteriostatic conc. interfere with cell wall transport system, and it lasts 8-12hrs
What type of mouth rinse's mechanism of action is effective against gram-negative and positive bacteria?
triclosan - bisphenol and nonionic
What type of mouth rinse's mechanism of action is bacteriolysis: causes leakage of cell contents by acting on microbial cyctoplasmic membrane?
triclosan antimicrobial agent
What type of mouth rinse's mechanism of action has a low toxicity?
What type of mouth rinse's mechanism of action is to disrupt cell walls/inhibit bacterial enzymes; it has poor substantivity, and decreases the pathogenicity of biofilm?
phenolic-related essential oils
What type of mouth rinse's mechanism of action has cationic agents that bind to oral tissue, ruptures cell wall and alters cytoplasm, strong intitial attachment, decreases bacterial attachment to pellicle, and has a low substantivity?
quaternary ammonium compounds
What type of mouth rinse's mechanism of action uses oxygen that acts to debride area, alters bacterial cell membrane, and has low substantivity?

List 2 considerations for the use of fluoride.
stannous type may stain teeth
List 4 considerations for the use of chlorhexidine.
it has low toxicity - poor absorption thru mucous membranes
stains teeth and restorations
increase in supra calc formation
minor soft tissue irritation; desquamation of oral mucosa
Why should you eat before rinsing with chlorhexidine?
because it may alter your taste perception
Why should you wait at least 30 minutes after brushing before you rinse with chlorhexidine?
because the sodium lauryl sulfate (detergent) in dentifrice will inactivate the chlorhexidine
