VLE introduction and caries risk assessment Flashcards
what are the 3 factors of restorative dentistry?
- prevention
- treatments
- Maintenance
what is involved in prevention?
- risk assessment
- education and preventive measures
- reassessment
what is involved in treatments?
- stabilisation -periodontal diseases , caries, erosion
- rehabilitation includes simple and complex restorations
why is maintenance needed?
restorations don’t last forever
what is dental caries?
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
what are key facts of dental caries?
- Dynamic process
- Balance between demineralization and remineralization
- pH < 5.5 favours demineralization
- pH > 5.5 favours remineralisation
- Individuals saliva buffering power
Describe the caries risk assessment.
- Informs and underpins effective preventive measures
- Takes many forms
Describe a cardiogram.
- 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
what is risk?
- The probability that some harmful event will occur
- May be within a specified period of time
what is caries risk?
- “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.
what factors are to be considered for caries?
- harmful
- protective
- past experience
What does DMFT stand for?
decayed missing filled teeth
what does DMFS stand for?
decayed missing filled surfaces
what does DMFT exclude?
wisdom teeth
when is DMFT less robust and why?
- elderly
- more teeth lost through perio
what does DMFS stand for?
decayed missing filled surfaces
what does DMFS exclude?
wisdom teeth
what is the max score of DMFS?
128
how many surfaces do anterior teeth have ?
4 surfaces - no incised edge
how many surfaces do posterior teeth have?
5 surfaces
what are surfaces with both caries and restoration scored?
D
what factors are to be considered when assessing caries to do with related general diseases?
- related general diseases - record medical history and medications
- reduced salivary flow (medication and radiation0
- dietary behaviour
- impaired mobility
what factors are to be considered when assessing caries to do with diet?
- Consider both content and frequency of fermentable carbohydrate
- Achieve by dietary diary
- A lactobacillus test count may also be helpful
what factors are to be considered when assessing caries to do with oral hygiene?
-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
what factors are to be considered when assessing caries to do with bacteria?
Estimation of levels of mutans streptococci may be helpful.
what factors are to be considered when assessing caries to do with salvia?
flow rate in unstimulated and stimulated circumstances
-buffer capacity
what factors are to be considered when assessing caries to do with fluoride?
Fluoride Exposure:
-Diet, Water, Oral hygiene products
what factors are to be considered when assessing caries to do with clinical judgment?
likelihood of compliance of patient with advice given
