0 - 5
6 - 9
10 - 12
What are the 5 high risk disease indicators?
- Frequent or prolonged between meal exposure to sugary or starchy foods/drinks
- visibly cavitated lesion or radiographic penetration into dentin
- 3 or more cavitated or non-cavitated carious lesions in the last 24 months
- teeth missing due to caries in the last 24 months
- severe dry mouth (xerostomia)
Disease indicators score ______ points.
10
What are the risk levels and associated scores?
Low Risk: score of 0
Moderate Risk: score of 1-9 (no disease indicators)
High Risk: score of 10 or more
How many disease indicators does it take to reach high risk?
1
Risk factors score _____ points.
1
How many risk factors does it take to reach moderate risk?
1
How many risk factors can a patient have before reaching high risk?
up to 9 is moderate
above 9 is high risk
What is the bitewing recommendation for low risk patients?
every 24-36 months
What is the bitewing recommendation for moderate risk patients?
every 6-18 months
What is the bitewing recommendation for high risk patients?
every 6-18 months
What is “caries”? (the two key points)
- Caries is a BACTERIAL infection caused by acidogenic bacteria in tooth biofilm
- Caries is a multifactorial PROCESS of tooth demineralization and remineralization which, until cavitation, is reversible
The FDI supports the principles of _____ _______ dentistry in the management of dental caries.
minimal intervention
What are the five FDI basic Cambra Principles?
- Modification of the oral flora to favor health
- Patient education and informed participation
- Remineralization of non-cavitated lesions of enamel and dentin/cementum
- Minimal operative intervention of cavitated lesions and defective restorations
- Repair of defective restorations
What is modification of the oral flora?
primary focus should be on control of the infection, plaque control, and reduced carbohydrate intake
What is patient education?
the etiology of dental caries should be explained to the patient, together with the means of prevention through dietary and oral hygiene measures
______ plays a critical role in the demin/remin cycle
Saliva
True or False: there is strong evidence that “white spot” lesions of enamel and non-cavitated lesions of dentin can be arrested or reversed.
True
What tooth factor determines the success of a restoration?
the remaining tooth structure (aka: use minimal operative intervention)
True or False: Removal of restorations results in an inevitable increase in cavity size as a consequence of removal of sound tooth structure.
True
_______ of defective restorations should be considered as an alternative to replacement in some circumstances.
Repair
How much sugar do americans eat per day?
22.7 tsp
How many bacteria have been identified as potentially carcinogenic?
50
The new theory of microbial communities insists that there is a tremendous number of diverse bacteria that function as a ________.
superorganism
The _______ generated from sugar metabolism, not the sugar availability, is what changes microbial homeostasis in dental plaque.
low pH
Under physiological conditions, saliva and oral fluids are _______ with respect to hydroxyapatite and fluorapatitie.
supersaturated
True or False: if the oral fluids were unsaturated with respect to apatite, the dental hard tissues would dissolve without other reason.
True
Transformation kinetics is a rate law that is a function of the pH at a constant _______.
Temperature
Below pH _______ the HA favors demin.
5.5
