Community Water Fluoridation Flashcards
Topical F
applied to tooth
Systemic F
taken into the body
Factors causing caries
host, agent (bacteria), time, environment (diet)
fluoridation
the adjustment of the F content of a community’s water supply for an optimal [c] for prevention of dental caries-one of the Ten Greatest Public Health Achievements during the 20th century
Colorado Brown Stain
ID’d in Colorado by Dr. F McKay that F was causing mottle enamel
Coined the term dental fluorosis and an index to classify its severity
Dr. H T. Dean-U.S. Public Health Service Worker
First community water fluoridation program was where
Grand Rapids MI
in 1962 it was determined that water F concentration should be based on ________ (think consumption)
region temperature-hotter=drink more water
U.S. Dept. HHS recommends a level of _____ mg/L or ppm for all community water? Before this what range was accepted
0.7; before it was 0.7-1.2ppm but above 1 starts causing dental fluorosis
in 2014 the HSH decided that all regions should have ____ppm F in water, because _____ did not change intake of F
0.7ppm
Temperature (did not matter)
Past thought mechanism of action of F
believed to be incorporated into the developing tooth enamel, a benefit to children’s health only
Dental caries more or less prevalent today?
Less among all ages (lower DMF scores)
fluorosis rates trend
increasing
Current mechanism of action of F (what we think now)
F works best to control caries when constantly present in low ambient levels in the oral cavity (minor pre-eruptive action), benefits people of all ages
Post-eruptive mech of action of F
inhibition of demin of sound enamel, enhancement of remin during repeated de/remin cycles, inhibit bacterial activity (less action production)
Pre-eruptive mechanism of action of F
NOT proven….. incorporated into the enamel, reduce solubility, more caries-resistant
How is F most effective
low concentrations over a long period of time
