Uptake and retention of fluoride by intact and etched enamel. 1975

U Belser, and S Spörri, and H R Mühlemann

180 fluoride biopsies were taken in 30 children from the labial surfaces of the 6 maxillary anterior teeth. The average thickness of the biopsied surface enamel was 8.35+/-0.75 mjm. Intact, not treated enamel had an average F-content of the integral of 550 ppm. 7 days after one 3-min topical application of amine fluoride on intact enamel the average F-concentration was the integral of 1150 ppm. 7 days after one amine fluoride application on enamel previously etched with pyruvic or orthophosphoric acid, the average F-content was the integral of 3400 ppm and the integral of 2800 ppm respectively.

D003743	Dental Enamel	A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath.
