– The Crystalliazation of human dentin and enamel containing different concentrations of Zn was Studied using X‐ray diffraction analysis. The concentrations of Ca, Mg, Mn, Fe, Zn, Cu, Go, Ni, Sr and Pb in the samples were determined by atomic absorption apectrophotomelry. The concetration foF was Assayed with a combination fluoride electrode. The increase of the Zn ceoncentration (ug/g) from 150 to 572 in dentin was found to intensify apatite refectins indicating changes paralled to c‐axis.A slight increase parallel to a‐axis (or better crystallization) of latices was demonstrated in both dentin and enarnel. The increase of Zn concentratin from 164 ug/g inenamel weakened 002 and 112 reflections. The effect of Zn on the crystallinitv of svnthetic apatite drepareda at 37°C was of the same kind as its effect onthe dentin.
