Optimal fluoride in water = 0.7ppm current recommendation
Pit and fissure sealants = most effective caries prevention
Fluoride varnish = 22600ppm NaF
APF gel = 1.23 percent = 12300ppm
Fluorosis = Deans index for classification
SMART fluoride = silver modified atraumatic restorative treatment
SDF = silver diamine fluoride = arrest caries
GIC sealant = fluoride releasing alternate.
