Lec 3

Question 1

carious lesion is more blank than enamel

Answer 1

radiolucent (dark) (high IMAGE density)

Question 2

need this much mineral loss before caries show up on radiograph

Answer 2

40-50%

Question 3

most common radiograph to detect caries

Answer 3

bitewing

Question 4

reading an x ray properly

Answer 4

trace around enamel, trace around dej, trace around restorations

Question 5

most interproximal lesions occur here because its hard to brush there

Answer 5

contact area

Question 6

caries reaching the dentin radiate out compared to enamel because

Answer 6

dentin isnt as strong

Question 7

occlusal caries are not detected very well by radiography because

Answer 7

caries must go through quite a bit of mineral before it would show up compared to interproximal

Question 8

lingual/facial lesions are on opposite sides but according to radiography

Answer 8

it looks the same so we dont know which side it’s actually on

Question 9

cemental/root surface caries are sometimes called blank

Answer 9

senile caries

Question 10

senile caries are due to

Answer 10

old people not being able to take good care of their teeth

Question 11

caries around a restoration

Answer 11

recurrent/secondary

Question 12

deep caries all over the place

Answer 12

rampant

Question 13

these restorations are very difficult to see in radiographs but will usually have a smooth border which defines them

Answer 13

composite

Question 14

this is a loss of minerals at the cej

Answer 14

cervical burnout

Question 15

cervical burnout vs caries detection

Answer 15

cervical burnout pretty nicely follows cej

Question 16

grinding teeth can lead to this on teeth surface that could be confused with occlusal caries

Answer 16

attrition
