Epidemiology of Caries (Cappelli) Flashcards
Dental caries is a diet-dependent, communicable, microbiologically-mediated ______ that follows an _____ and ____ disease pathway.
- Disease
- Infectious and chronic
Measure of disease frequency that quantifies the proportion of a population who has the disease at a specific time and provides an estimate of the risk that an individual will have the disease at a given point in time.
Prevalence
Quantification of the number of new cases of a disease that develops in a population of individuals at risk during a specific time interval.
Incidence
Most often, population measures calculate _____ of disease.
Prevalence
Can measure ____ or development of new lesions over time (usually minimum of three years).
Incidence
____ are frequently used to measure disease in populations.
Indices
DMF Index
D: # of teeth or surfaces that are DECAYED
M: # of teeth or surfaces that are MISSING (due to caries)
F: # of teeth or surfaces that are FILLED
The DMF index measures the ______ of coronal caries in populations.
Prevalence
The DMF Index is ____ and can be applied to ____ or ____.
- Irreversible
- Whole tooth (DMFT) or number of surfaces (DMFS)
DMFT calculation
(DT+MT+FT)/n
n=number of subjects
DMFS calculation
(DS+MS+FS)/n
n=number of subjects
Rules for DMF: if there is recurrent decay, ____ takes precedence over ____.
- Decay (D)
- Filled (F)
Rules for DMF: each tooth or surface is counted ______.
Only once
Rules for DMF: _____ are not included.
Third molars
Limitation of DMF
- Not related to total number of teeth at risk
- Equal weight to missing, untreated decay, or well-restored teeth
- Can overestimate in teeth with “preventive resin restorations”
- Cannot be utilized to estimate treatment need
- Does not account for sealed teeth
