In India, we are restricting the entry of fluoride into the body by removing fluoride from drinking water and creating awareness on the harmful side effects of using fluoridated dental products viz. tooth paste, mouth rinse, tablets etc. The reason being that by using fluoridated toothpaste, fluoride does enter blood circulation within minutes. This has been confirmed by testing the fluoride level in blood before and after brushing with toothpaste containing fluoride. This has been proved in children of 5-10 years and 10-14 years of age respectively. The data is provided in the Bar diagrams 1 & 2.
Bar Diagram- 1
Serum fluoride level (in ppm) in children of 5-10 years using toothpaste (containing 900 ppm fluoride) once a day
Mean (N=10) ± SD:
Student’s ‘t’ test 3rd day p <0.01, 6th day P <0.005, 9th day P < 0.001
Bar Diagram 2
Serum Fluoride level (in ppm) in children of 10-14 years, using toothpaste containing 1100 ppm fluoride
Mean (N=10) ± S.D. :
Paired ‘t’ test 1st day P<0.05, 3rd day P<0.01, 6th day N.S, 9th day P <0.025
