Question 4

– Rampant caries :

Answer 4

suddenly appearing, widespread, rapidly progressing type of caries, with advanced and severe decay on multiple surfaces of many teeth.
be found in people who have an abnormal lack of saliva = xerostomia

Question 5

radiation-induced caries

Answer 5

radiation to the __head______ and _____neck

Question 6

Incipient caries

Answer 6

lesion on a tooth which was previously demineralized but was remineralized before causing a cavitation.

Question 7

Chronic caries

Answer 7

condition that has taken an extended period of time to develop

Question 8

Recurrent / secondary caries

Answer 8

A caries which appears at a location with a previous history of decay (often on the margin of fillings or other dental restorations).

Question 9

Arrested carie

Answer 9

A caries found at a location that has not experienced previous decay

– Pit and fissure caries

Question 11

class II caries

Answer 11

Proximal /interproximal caries On posterior teeth

Question 12

class _III__ caries

Question 13

class _IV__ caries

Answer 13

incisal edge is not included

On anterior teeth

Question 14

Root caries

Answer 14

generally due to gingival recession
most commonly located on mandibular molars, followed by mandibular premolars, maxillary anteriors, maxillary posteriors and mandibular anteriors

Question 15

class __V_ caries

Answer 15

any other smooth surfaces of enamel except interproximal areas

Question 16

class __VI_ caries

Answer 16

located on cusp tips of posterior teeth or incisal edges of anterior teeth

Question 17

ordre signs caries

Answer 17

1 A chalky white spot The decay is incipient (beginning).

2) Brown spot = reversible
3) cavitatioon = irreversible

Question 18

The lesion is brown and shiny.

Answer 18

Dental caries were once present but the demineralization process has stopped, leaving a stain.

Question 19

A brown spot which is dull (terne) in appearance.

Answer 19

A sign of active caries

Question 20

Four elements are necessary for caries to form :

Answer 20

– 1 – A tooth surface (enamel or dentin)
– 2 – Caries-causing bacteria
– 3 – Fermentable carbohydrates (such as sucrose)
– 4 – Time

Question 21

pH début déminéralisation de l’émail

Answer 21

below ____5,5______

Question 22

the two bacteria which are considered responsible for cavities

Answer 22

Streptococcus _____________________ mutans

- Lactobacilli ____________________

Question 23

risk factors caries

Answer 23

– Reduced saliva + – Reduced saliva

Question 24

four zones caries

Answer 24

• The translucent zone = deepest layer of the enamel + first visible sign of caries
• The dark zone = slight remineralization of enamel
• The body of the lesion = greatest demineralization
• The surface zone = relatively mineralize + present until the loss of tooth structure results in a cavitation.

Question 25

The dentin, unlike the enamel, develops three zones affected by caries

Answer 25

• translucent zone = deepest layer of dentin + advancing front of the carious process and it is where the initial demineralization begins
• zone of destruction = between the two other zone = where bacteria attack and where the dentin will decompose
• The zone of bacterial penetration = Surface closest to the enamel

Question 26

If the odontoblasts live long enough to react to the dental caries, the dentin which is then ______produced_______ is named

Answer 26

« reactionary » dentin

Question 27

, if the odontoblasts are killed, the dentin produced is called

Answer 27

« reparative » dentin

Question 28

palatal caries

Answer 28

Caries located on the lingual surfaces of maxillary teeth and are located beside the hard palate.
