Lec 2 Flashcards
proximal lesion on outer half of enamel
e1
proximal lesion to inner half of enamel
e2
proximal lesion on outer third of dentin
d1
proximal lesion on middle third of dentin
d2
proximal lesion on inner third of dentin
d3
fill teeth and open them up if they are these icdas or these proximals
4,5,6
d2,d3
do not open up teeth with these icdas or proximals
0,1,2
E1, E2
these icdas or proximals are up to the individual dentist
3, d1
determination of how likely patient is to develop new lesions in the near future
caries risk assessment
three classifications for caries risk assessment
low, moderate, high
three things needed for caries
microflora, host, substrate
three criteria of carries risk assessment
disease indicators, risk factors, protective factors
any yes circled in this column automatically results in high risk
disease indicators
disease indicators
visible cavities or lesions that penetrate into dentin, active proximal lesions, active white spots that are rough, restorations from caries in last 3 years, extractions from caries in last 3 years
risk factors column show us how we can blank
prevent new caries
risk factors
visible plaque, deep pits/fissures, saliva reducing factors like meds, dry mouth, restorations with overhangs, exposed roots, ortho appliances/partial dentures, infrequent or irregular dental care, frequent snacks, high sugar intake, recreational drug use
1 risk factor means blank risk level
moderate sometimes low
more than one risk factor means blank risk level
moderate sometimes high
mineral component of enamel
hydroxyapatite
mechanism of cavity formation
bacteria eat sugar and make acidic plaque that eats away hydroxyapatite
pH above 5.5 allows sodium fluoride to assist with blank
remineralization
pH between 4.5 and 5.5, sodium fluoride can blank
inhibit demineralization
pH below 4.5 sodium fluoride can blank
do nothing
protective factors do not change blank
risk level
