Question 20

define cariology

Answer 20

science and study of dental caries

Question 21

define carious lesion

Answer 21

decayed site/area on tooth

Question 22

define dental caries

Answer 22

disease of the mineralized structures of the teeth characterized by demineralization of the hard components and dissolution of the organic matrix
-single or multiple area of decay are always referred to as caries

Question 23

define arrested caries

Answer 23

also known as inactive caries

carious lesion that has become stationary and doesn’t show a tendency to progress further

Question 24

define backward caries

Answer 24

also known as internal caries
lateral spread of decay at the DEJ through the undermining process
the surface lesion appears small but the destruction is extensive underneath

Question 25

define incipient caries

Answer 25

also known as primary caries or early lesion

occurs on a surface not previously affected

Question 26

define rampant caries

Answer 26

progressive caries occurring in many teeth simultaneously

Question 27

what is the difference between acute rampant and chronic rampant caries

Answer 27

acute: rapid progression
chronic: slow developing

Question 28

define recurrent caries

Answer 28

also known as secondary caries
carious lesion at the margin of or adjacent to an existing restoration
radiolucent area under an existing restoration which may be due to poor cavity preparation defective margins of restoration or incomplete removal of placement restoration

Question 29

define early childhood caries

Answer 29

addressing caries process with the primary dentition
rampant smooth surface decay requiring urgent intervention formerly known as baby bottle caries or nursing bottle syndrome
