Abstract:
The four enamel pieces,which are from one bovine tooth,are treated individually by 2.7% NaF gel(pH4),2.7% NaF gel(pH7),1%NaF gel (pH7.0) and the control group gel.The fluoride amount in enamel pieces is measured by fluoride electrode.The aim of present study is to observe the changer of enamel intake of fluoride amount when the pH and fluoride concentration varies.In results the most fluoride amount in enamel pieces treated by 2.7% NaF gel(pH4) is measured.The more fluoride amount is measured in group of 2.7%NaF gel(pH7) than 1% NaF gel (pH7).The Results show lower pH and higher fluoride concentration can increase more fluoride amount in enamel.

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
