Caries Symposium Flashcards
diagnosis and classification
D1 classification
clincially detectable enamle lesions with intact surfaces
diagnosis and classification
D2 Classification
clinically detectable “cavities” in enamel
diagnosis and classification
D3 classification
clinically detectable lesions extended into dentine
diagnosis and classification
How to determine if caries is cavitated or not?
determined by using perio probe/blunt probe eg. WHO or UNC
- if you feel a catch = cavitated
- If it runs smoothly = Not cavitated
diagnosis and classification
What is active and inactive caries?
Active: demineralising
Inactive: remineralising
diagnosis and classification
What does primary or secondary caries suggest?
Location
- Primary: no restoration present
- Secondary: adjacten to restoration
diagnosis and classification
How is diagnostic accuracy measured?
Reliabilty
- measures what is claimed (accuracy)
- consistency of measurement (precision)
Accuracy
- Sensitivity
- Specificity
Risk assessment
What are the factors necessary for caries
3
- Susceptible tooth surface
- Substrate
- Flora (bacteria)
Risk assessment
Give examples that may cause a tooth surface to be susceptible to caries
- Age
- amount of fluoride tooth subjected to
- morphology
- nutrition
- trace elements
- carbonate level (carbohydrate substrates)
Risk assessment
Give examples of substrate factors that may contirbute to caries
- oral clearance
- oral hygiene
- quality/quantity of saliva
- freq. of eating
- carbohydrate (type, conc)
Risk assessment
Give examples of general Caries risk factors
- Social
- General health
Risk assessment
Give examples of local caries risk factors
- OH
- diet
- fluoride exposure
- past caries experiences
- orthdontic treatment
Risk assessment
What are the 7 elements which help deteremine caries risk?
- Clinical evidence
- Dietary habits
- Social history
- Fluoride use
- Plaque control
- Saliva
- Medical History
Describe the 3 main actions of fluoride to help revent caries
- incorporates into enamel crystal to form flurorapatite which is more resistant to demineralisation (therefore more caries resistant) than HA.
- antimicrobial effect reduces acid tolerance of bacteria (acts best in acidic pH’s), interferes with glycolysis/metabolism
- interferes with the adhesion force of bacteria reducing their ability to stick to the surface of the teeth
