Flashcards in Lecture 3 Deck (20):
study/analysis of patterns, causes, and effects of health and disease conditions in defined populations. Cornerstone of public health.
dynamic sequence of biofilm interactions that can occur over time on and within a tooth surface
shift in balance between protective and destructive factors in favor of demineralization
How does fluoride work topically?
Plaque on teeth is the reservoir for fluoride
Positive ions come off: calcium, phosphate, carbonate
Fluoride will attach to a demineralized area and brings in the positive ions
Nowadays what else is included in substrate, host, and time?
community level influences, family level influences, and child level influences
What is the Stephan curve?
• When pH goes below 5.5, (happens usually after you eat) it takes about 20 min to get back up to about 5.5
When you are below 5.5 your teeth are getting attacked by acid
demin and remin balance
caries at one point in time
new carious lesions over a specific time period
change of differences in prevalence or incidence over time; may also be reported by location, by age, by gender, by socioeconomic status, by ethnicity, by educational attainment
population represented by age, sex, ethnic/racial group, SES
How are differences assessed?
demographics, geographical location, and trends influenced by sampling, methods used to collect data, and analytical techniques
What were the outcomes of trends associated in study with percentage of children aged 2-4 who ever had caries in primary teeth?
• Disease increased during most recent times
• More males than females
• Every 10 years we tend to see tooth decay go down, this study was different (it compared 1988-1994 w/ 1999-2004)
• More disease in underserved ethnic populations
• In white population, there was significant increase.
• If you had decay, then you would most likely have decay again
In the last 10 years, this trend has gone down again.
describe adult caries experience
over 90% of adults have caries, DMF increases w/ age mostly due to M, and more adults are retaining teeth
females have greater DMF scores, which may be a function of treatment seeking
research is ongoing related to genetic factors but environments/psychological factors play a major role
about 25% of people older than 18 show root caries
root caries increase w/ age, related to root exposure, medications, and numbers of retained teeth
cost of dental care - $110 B, 4% of total health care cost
dental disease at #3
use of fluoride was noted to have saved about $40 billion between 1960 and 2000
caries risk assessment
analysis of probability that the number, size, or activity of lesions will change over a specified period of time (standardized way to look at risk)
What are some obstacles of caries risk assessment?
only 14% of dentists do CRA, most use observation/experience
reimbursement, no universally accepted system
really only for kids
checklist of 19 factors associated with caries, adult and child versions, no published studies on validity, no published ADA guidelines
