tályszerkezet-módosító hatásainak felhasználására a fog keményszöveteiben is.

Kezdeti eredményeink bizonytalansága azonban jelzi, hogy további tisztázó kísérletek szükségesek a ritkaföldfémeknek a hidroxi-apatit-rácsba való beépülési mechanizmusának felderítésére.

Dr. Gintner, Z. and dr. Bánóczy, J.: Effect of rare-earth elements' (REE) containing toothpastes on the acid-solubility of human dental enamel, in vitro.

The effect of different REE containing toothpastes has been studied on human dental enamel, in an experimental model, using diluted suspensions of toothpastes. The grade of remineralisation has been characterised bv the amount of dissolved phosphorus from the enamel samples. All the investigated-, REE containing toothpastes decreased the acid-solubility of dental enamel, the best results were found in the group of samarium-containing toothpastes.
