Prevention of Dental Caries Flashcards
what ar the main factors asscw it caries
teeth
plaque bacteria
sugar
time
what is important for the teeth
diet - resistance
add fluoride
use protective covers - fissure selects
what is imp for the plaque bac in caries
removal - mech?chem
vaccination - cariogenic bac
how does sugar influence carrie
improve diet
restrict fermentable carbs
how does time have an effect on caries
sugar in contact with teeth
avoid snacking
what is the term used to describe plaque bac
acidogenci
how is complete removal carried out for plaque control
not 100% bac recolonise tooth flossing scale polish brush - fluoride
what does toothbrushing reduce
gingivitis
what are the properties of disclosing gents
non toxic taste easily removed from mouth after use good colour contrast inexpensive
what are some common dyes and chess used as disclosing agent
bismarck brown
erythrosin (common stain tongue, lips etc)
what colour doe erytrosin
red
what are the chemical methods of control of plaque
antibiotics
antiseptics
enzymes
why are antibiotics not thought as a method plaque control
disrupt normal oral flora - albicans
hypersensitivity
storage
reisstance
what is an effective antiseptic used in toothpastes
chlorhexidine
what simp about chlrohexididne
gm +ve/-ve
s mutans more sensitive
what is the interaction of chlorhexidine and fluoride
high risk patients
radiation caries
what are some problems assc with chlorhexidine
taste
staining
disrupts flora back throat
what does STAMPS stand for
sp targetted anti microbial peptides
what are STAMPS
co joined peptides
sp and antimicrobial
in vitro activity
combine with replacement therapy
what are some enzymes assc with plaque control
single or mix
dextranases
mucinases polysacc
what are some disadvantages of anti plaque enzymes
not very effective
enzymes dont sore wil n tooth paste
sp
are proteins = hypersentisivtiy
what are some sugar alteatives
saccharine
xylitol
what are some detersive foods
apples, carrots
little evidence
explain xylitol
sugar alcohol
sucrose replace? added
sucres replacement
reduce MS bac
what is raw starch - unrefined
not cariogenic poorly deign by alpha amylase - s mutans - s mites - A viscous
what does s sanguines and mites produce
alpha amylase
what is a cooked starch
cariogenic in man
potatoes, popcorn
what is replacement therapy
replace pathogenic bac by non pathogenic
how does the colonisation of host with the effects strain in repaceemtn therapy
reduced cariogenic potential
displace existing s mutans
perssostn in s mutans sites
safe
what are the defector staring harm
harmless by inoculate host at easy age
displace existing strains with ne on
what can displaces s mutans
s salivarius
