Module 1 - Introduction

Question 1

Latin meaning of ‘Caries’

Answer 1

Dry rot

Question 2

Implies slow disintegration of any biological hard tissue as a result of bacterial action

Answer 2

Caries

Question 3

defined it as a localized posteruptive, pathological process of external origin involving softening of the hard tooth tissue and proceeding to the formation of a cavity.

Answer 3

WHO

Question 4

defined it as the chemical dissolution of the calcium salts, first of the enamel then of the dentin by lactic acid

Answer 4

GV Black (Green Vardiman)

Question 5

Tooth demineralization as a result of the caries process.

Answer 5

Caries Lesion

Question 6

A caries lesion on a smooth tooth surface.

Answer 6

Smooth-surface caries.

Question 7

A caries on a pit and fissure area

Answer 7

Pit-and-fissure caries.

Question 8

A caries lesion on an occlusal surface.

Answer 8

Occlusal caries.

Question 9

A caries lesion on a proximal surface.

Answer 9

Proximal caries.

Question 10

A caries lesion in enamel, typically indicating that the lesion has not penetrated into dentin.

Answer 10

Enamel caries.

Question 11

A caries lesion into dentin.

Answer 11

Dentin caries

Question 12

A caries lesion on any surface of the anatomic tooth crown.

Answer 12

Coronal caries

Question 13

A caries lesion in the root surface.

Answer 13

Root caries.

Question 14

A caries lesion not adjacent to an existing restoration or crown

Answer 14

Primary caries.

Question 15

A caries lesion adjacent to an existing restoration, crown or sealant.

Answer 15

Secondary or Recurrent caries

Question 16

Refers to carious tissue that was not completely excavated prior to placing a restoration. Sometimes it is difficult to differentiate it from secondary caries.

Answer 16

Residual caries.

Question 17

A caries lesion that results in the breaking of the integrity of the tooth, or a cavitation.

Answer 17

Cavitated caries lesion.

Question 18

A caries lesion that has not been cavitated. In enamel caries, non-cavitated lesions are also referred to as “white spot” lesions

Answer 18

Non-cavitated caries lesion.

Question 19

A caries lesion that is considered to be biologically active, is a lesion in which tooth demineralization is in frank activity at the time of examination.

Answer 19

Active caries lesion.

Question 20

A caries lesion that is considered to be biologically inactive at the time of examination, that is, in which tooth demineralization caused by caries may have happened in the past but has stopped and is currently stalled.

Answer 20

Inactive caries lesion

Question 21

Also referred to as “arrested caries”

Answer 21

Inactive caries

Question 22

A term used to describe the presence of extensive and multiple cavitated and active caries lesions in the same person.

Answer 22

Rampant caries

Question 23

Typically associated with “baby bottle caries” “radiation therapy caries” or “meth-mouth caries”

Answer 23

Rampant caries

Question 24

formerly known as “baby bottle caries”

Answer 24

Early Childhood Caries

Question 25

Critical level of pH for enamel and dentin

Answer 25

5.5 enamel, 6.2 dentin

Question 26

Characteristics of Active caries

Answer 26

Brown, soft, painful

Question 27

Characteristics of Inactive caries

Answer 27

Black, hard, not painful

Question 28

Bacteria that causes enamel caries

Answer 28

Streptococcus mutans

Question 29

Bacteria that causes dentinal caries

Answer 29

Lactobacillus acidophilus

Question 30

Bacteria that cause root caries

Answer 30

Actinomyces Actinomycetemcomitans

Question 31

Relationship between fluoride content and caries susceptability

Answer 31

Inversely proportional

Question 32

Relationship between saliva viscosity and caries susceptability

Answer 32

Directly proportional

low viscosity > flowable saliva > low susceptibility

high viscosity > thick/sticky saliva > high susceptibility
