VLE introduction and caries risk assessment

Question 1

what are the 3 factors of restorative dentistry?

Answer 1

• prevention
• treatments
• Maintenance

Question 2

what is involved in prevention?

Answer 2

• risk assessment
• education and preventive measures
• reassessment

Question 3

what is involved in treatments?

Answer 3

• stabilisation -periodontal diseases , caries, erosion

- rehabilitation includes simple and complex restorations

Question 4

why is maintenance needed?

Answer 4

restorations don’t last forever

Question 5

what is dental caries?

Answer 5

A bacterial disease of the calcified tissues of the teeth characterized by demineralization of the inorganic and destruction of the organic substance of the tooth

Question 6

what are key facts of dental caries?

Answer 6

• Dynamic process
• Balance between demineralization and remineralization
• pH < 5.5 favours demineralization
• pH > 5.5 favours remineralisation
• Individuals saliva buffering power

Question 7

Describe the caries risk assessment.

Answer 7

• Informs and underpins effective preventive measures

- Takes many forms

Question 8

Describe a cardiogram.

Answer 8

• Illustrates the interaction of caries related factors
• Illustrates the chance to avoid caries
• Expresses caries risk graphically
• Recommends targeted preventive actions
• Can be used on the clinic
• Can be used as an educational programme

Question 9

what is risk?

Answer 9

• The probability that some harmful event will occur

- May be within a specified period of time

Question 10

what is caries risk?

Answer 10

• “The probability that a person will develop carious lesions, reaching a given stage of the disease in progression during a specified period of time, conditional that the exposure status for risk factors remains stable during the period in question.”
• Modifying behaviour thus changes risk.

Question 11

what factors are to be considered for caries?

Answer 11

• harmful
• protective
• past experience

Question 12

What does DMFT stand for?

Answer 12

decayed missing filled teeth

what does DMFS stand for?

Answer 13

decayed missing filled surfaces

Question 14

what does DMFT exclude?

Answer 14

wisdom teeth

Question 15

when is DMFT less robust and why?

Answer 15

Answer 20

5 surfaces

Question 21

Answer 21

D

Question 22

what factors are to be considered when assessing caries to do with related general diseases?

Answer 22

• related general diseases - record medical history and medications
• reduced salivary flow (medication and radiation0
• dietary behaviour
• impaired mobility

Question 23

what factors are to be considered when assessing caries to do with diet?

Answer 23

• Consider both content and frequency of fermentable carbohydrate
• Achieve by dietary diary
• A lactobacillus test count may also be helpful

Question 24

what factors are to be considered when assessing caries to do with oral hygiene?

Answer 24

-Estimation of plaque:
-% index may be helpful
0 = < 5%, 1 = 5-20%, 2 = <20-50%, 3 = > 50%
-Use of disclosing agent helpful

-Plaque retentive factors:
Crowded teeth
Overhanging restorations
No contact point restorations

Question 25

what factors are to be considered when assessing caries to do with bacteria?

Answer 25

Estimation of levels of mutans streptococci may be helpful.

Question 26

what factors are to be considered when assessing caries to do with salvia?

Answer 26

flow rate in unstimulated and stimulated circumstances | -buffer capacity

Question 27

what factors are to be considered when assessing caries to do with fluoride?

Answer 27

Fluoride Exposure: | -Diet, Water, Oral hygiene products

Question 28

what factors are to be considered when assessing caries to do with clinical judgment?
