Sažetak
The incorporation of lanthanides in human dental enamel was investigated by means o f X-ray microprobe analysis. Sound human premolar teeth - after extraction-were prepared and kept for 60 days in 10% solutions of neodymium-, samariumeuropium-, ytterbium resp. lanthanum-chloride at room temperature with constant shaking. Results of the X-ray microprobe analysis revealed 100-140 m depth penetration and incorporation o f neodymium, with transformation o f the apatite phases of enamel into neodymium-hydroxil-apatite-, resp. neodymium- hidrochlor-apatite. The changes were accompanied by a decrease in the values o f calcium, magnesium and sodium. Samarium- , ytterbium-, europium and lanthanum-chloride treatments produced a phosphate-complex containing coherent layer on the enamel surface. However, no real incorporation into the apatite-lattice was observed. The incorporation o f neodymium-apatites, and the formation of cerium-apatite into the dental enamel observed in previous studies might indicate the possibility of stabilizing the apatite structure, and discovering new ways of caries prevention.
